Detailed Description

A collection of billboards (faces which are always facing the given direction) with the same (default) dimensions, material and which are fairly close proximity to each other.

Remarks:
Billboards are rectangles made up of 2 tris which are always facing the given direction. They are typically used for special effects like particles. This class collects together a set of billboards with the same (default) dimensions, material and relative locality in order to process them more efficiently. The entire set of billboards will be culled as a whole (by default, although this can be changed if you want a large set of billboards which are spread out and you want them culled individually), individual Billboards have locations which are relative to the set (which itself derives it's position from the SceneNode it is attached to since it is a MoveableObject), they will be rendered as a single rendering operation, and some calculations will be sped up by the fact that they use the same dimensions so some workings can be reused.
A BillboardSet can be created using the SceneManager::createBillboardSet method. They can also be used internally by other classes to create effects.
Note:
Billboard bounds are only automatically calculated when you create them. If you modify the position of a billboard you may need to call _updateBounds if the billboard moves outside the original bounds. Similarly, the bounds do no shrink when you remove a billboard, if you want them to call _updateBounds, but note this requires a potentially expensive examination of every billboard in the set.

Constructor & Destructor Documentation

Ogre::BillboardSet::BillboardSet (   )  [protected]
 

Private constructor (instances cannot be created directly).

Ogre::BillboardSet::BillboardSet (  const String &  name,
unsigned int  poolSize = 20,
bool  externalDataSource = false
) 
 

Usual constructor - this is called by the SceneManager.

Parameters:
name The name to give the billboard set (must be unique)
poolSize The initial size of the billboard pool. Estimate of the number of billboards which will be required, and pass it using this parameter. The set will preallocate this number to avoid memory fragmentation. The default behaviour once this pool has run out is to double it.
externalDataSource If true, the source of data for drawing the billboards will not be the internal billboard list, but external data. When driving thebillboard from external data, you must call _notifyCurrentCamera to reorient the billboards, setPoolSize to set the maximum billboards you want to use, beginBillboards to start the update, and injectBillboard per billboard, followed by endBillboards.

virtual void Ogre::Renderable::_updateCustomGpuParameter (  const GpuProgramParameters::AutoConstantEntry &  constantEntry,
GpuProgramParameters *  params
)  const [virtual, inherited]
 

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.
You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.
Parameters:
constantEntry The auto constant entry referring to the parameter being updated
params The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity, and Ogre::TerrainRenderable.

virtual void Ogre::ShadowCaster::extrudeBounds (  AxisAlignedBox &  box,
const Vector4 &  lightPos,
Real  extrudeDist
)  const [protected, virtual, inherited]
 

Utility method for extruding a bounding box.

Parameters:
box Original bounding box, will be updated in-place
lightPos 4D light position in object space, when w=0.0f this represents a directional light
extrudeDist The distance to extrude

void Ogre::ShadowCaster::extrudeVertices (  HardwareVertexBufferSharedPtr  vertexBuffer,
size_t  originalVertexCount,
const Vector4 &  lightPos,
Real  extrudeDist
)  [static, inherited]
 

Utility method for extruding vertices based on a light.

Remarks:
Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.
Parameters:
vertexBuffer The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCount The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos 4D light position in object space, when w=0.0f this represents a directional light
extrudeDist The distance to extrude

virtual void Ogre::BillboardSet::setAutoextend (  bool  autoextend  )  [virtual]
 

Tells the set whether to allow automatic extension of the pool of billboards.

Remarks:
A BillboardSet stores a pool of pre-constructed billboards which are used as needed when a new billboard is requested. This allows applications to create / remove billboards efficiently without incurring construction / destruction costs (a must for sets with lots of billboards like particle effects). This method allows you to configure the behaviour when a new billboard is requested but the billboard pool has been exhausted.
The default behaviour is to allow the pool to extend (typically this allocates double the current pool of billboards when the pool is expended), equivalent to calling this method with autoExtend = true. If you set the parameter to false however, any attempt to create a new billboard when the pool has expired will simply fail silently, returning a null pointer.
Parameters:
autoextend true to double the pool every time it runs out, false to fail silently.

virtual void Ogre::BillboardSet::setBillboardOrigin (  BillboardOrigin  origin  )  [virtual]
 

Sets the point which acts as the origin point for all billboards in this set.

Remarks:
This setting controls the fine tuning of where a billboard appears in relation to it's position. It could be that a billboard's position represents it's center (e.g. for fireballs), it could mean the center of the bottom edge (e.g. a tree which is positioned on the ground), the top-left corner (e.g. a cursor).
The default setting is BBO_CENTER.
Parameters:
origin A member of the BillboardOrigin enum specifying the origin for all the billboards in this set.

virtual void Ogre::BillboardSet::setBillboardRotationType (  BillboardRotationType  rotationType  )  [virtual]
 

Sets billboard rotation type.

Remarks:
This setting controls the billboard rotation type, you can deciding rotate the billboard's vertices around their facing direction or rotate the billboard's texture coordinates.
The default settings is BBR_TEXCOORD.
Parameters:
rotationType A member of the BillboardRotationType enum specifying the rotation type for all the billboards in this set.

virtual void Ogre::BillboardSet::setBillboardsInWorldSpace (  bool  ws  )  [virtual]
 

Sets whether billboards should be treated as being in world space.

Remarks:
This is most useful when you are driving the billboard set from an external data source.

Definition at line 722 of file OgreBillboardSet.h.

virtual void Ogre::BillboardSet::setBillboardType (  BillboardType  bbt  )  [virtual]
 

Sets the type of billboard to render.

Remarks:
The default sort of billboard (BBT_POINT), always has both x and y axes parallel to the camera's local axes. This is fine for 'point' style billboards (e.g. flares, smoke, anything which is symmetrical about a central point) but does not look good for billboards which have an orientation (e.g. an elongated raindrop). In this case, the oriented billboards are more suitable (BBT_ORIENTED_COMMON or BBT_ORIENTED_SELF) since they retain an independant Y axis and only the X axis is generated, perpendicular to both the local Y and the camera Z.
In some case you might want the billboard has fixed Z axis and doesn't need to face to camera (e.g. an aureola around the player and parallel to the ground). You can use BBT_PERPENDICULAR_SELF which the billboard plane perpendicular to the billboard own direction. Or BBT_PERPENDICULAR_COMMON which the billboard plane perpendicular to the common direction.
Note:
BBT_PERPENDICULAR_SELF and BBT_PERPENDICULAR_COMMON can't guarantee counterclockwise, you might use double-side material (cull_hardware node) to ensure no billboard are culled.
Parameters:
bbt The type of billboard to render

void Ogre::BillboardSet::setBounds (  const AxisAlignedBox &  box,
Real  radius
) 
 

Set the bounds of the BillboardSet.

Remarks:
You may need to call this if you're injecting billboards manually, and you're relying on the BillboardSet to determine culling.

void Ogre::MovableObject::setCastShadows (  bool  enabled  )  [inherited]
 

Sets whether or not this object will cast shadows.

Remarks:
This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.
Note:
This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 337 of file OgreMovableObject.h.

virtual void Ogre::BillboardSet::setCommonDirection (  const Vector3 &  vec  )  [virtual]
 

Use this to specify the common direction given to billboards of type BBT_ORIENTED_COMMON or BBT_PERPENDICULAR_COMMON.

Remarks:
Use BBT_ORIENTED_COMMON when you want oriented billboards but you know they are always going to be oriented the same way (e.g. rain in calm weather). It is faster for the system to calculate the billboard vertices if they have a common direction.
The common direction also use in BBT_PERPENDICULAR_COMMON, in this case the common direction treat as Z axis, and an additional common up-vector was use to determine billboard X and Y axis.
See also:
setCommonUpVector
Parameters:
vec The direction for all billboards.
Note:
The direction are use as is, never normalised in internal, user are supposed to normalise it himself.

virtual void Ogre::BillboardSet::setCommonUpVector (  const Vector3 &  vec  )  [virtual]
 

Use this to specify the common up-vector given to billboards of type BBT_PERPENDICULAR_SELF or BBT_PERPENDICULAR_COMMON.

Remarks:
Use BBT_PERPENDICULAR_SELF or BBT_PERPENDICULAR_COMMON when you want oriented billboards perpendicular to specify direction vector (or, Z axis), and doesn't face to camera. In this case, we need an additional up-vector to determine the billboard X and Y axis. The generated billboard plane and X-axis guarantee perpendicular to specify direction.
See also:
setCommonDirection
The specify direction is billboard own direction when billboard type is BBT_PERPENDICULAR_SELF, and it's shared common direction when billboard type is BBT_PERPENDICULAR_COMMON.
Parameters:
vec The up-vector for all billboards.
Note:
The up-vector are use as is, never normalised in internal, user are supposed to normalise it himself.

virtual void Ogre::BillboardSet::setCullIndividually (  bool  cullIndividual  )  [virtual]
 

Sets whether culling tests billboards in this individually as well as in a group.

Remarks:
Billboard sets are always culled as a whole group, based on a bounding box which encloses all billboards in the set. For fairly localised sets, this is enough. However, you can optionally tell the set to also cull individual billboards in the set, i.e. to test each individual billboard before rendering. The default is not to do this.
This is useful when you have a large, fairly distributed set of billboards, like maybe trees on a landscape. You probably still want to group them into more than one set (maybe one set per section of landscape), which will be culled coarsely, but you also want to cull the billboards individually because they are spread out. Whilst you could have lots of single-tree sets which are culled separately, this would be inefficient to render because each tree would be issued as it's own rendering operation.
By calling this method with a parameter of true, you can have large billboard sets which are spaced out and so get the benefit of batch rendering and coarse culling, but also have fine-grained culling so unnecessary rendering is avoided.
Parameters:
cullIndividual If true, each billboard is tested before being sent to the pipeline as well as the whole set having to pass the coarse group bounding test.

void Ogre::Renderable::setCustomParameter (  size_t  index,
const Vector4 &  value
)  [inherited]
 

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters:
index The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value The value to associate.

All billboards in a set are created with these default dimensions. The set will render most efficiently if all the billboards in the set are the default size. It is possible to alter the size of individual billboards at the expense of extra calculation. See the Billboard class for more info.
Parameters:
width The new default width for the billboards in this set.
height The new default height for the billboards in this set.

virtual void Ogre::BillboardSet::setDefaultHeight (  Real  height  )  [virtual]
 

See setDefaultDimensions - this sets 1 component individually.

void Ogre::MovableObject::setDefaultQueryFlags (  uint32  flags  )  [static, inherited]
 

Set the default query flags for all future MovableObject instances.

void Ogre::MovableObject::setDefaultVisibilityFlags (  uint32  flags  )  [static, inherited]
 

Set the default visibility flags for all future MovableObject instances.

virtual void Ogre::BillboardSet::setDefaultWidth (  Real  width  )  [virtual]
 

See setDefaultDimensions - this sets 1 component individually.

virtual void Ogre::BillboardSet::setMaterialName (  const String &  name  )  [virtual]
 

Sets the name of the material to be used for this billboard set.

Parameters:
name The new name of the material to use for this set.

virtual void Ogre::BillboardSet::setPointRenderingEnabled (  bool  enabled  )  [virtual]
 

Set whether or not the BillboardSet will use point rendering rather than manually generated quads.

Remarks:
By default a billboardset is rendered by generating geometry for a textured quad in memory, taking into account the size and orientation settings, and uploading it to the video card. The alternative is to use hardware point rendering, which means that only one position needs to be sent per billboard rather than 4 and the hardware sorts out how this is rendered based on the render state.
Using point rendering is faster than generating quads manually, but is more restrictive. The following restrictions apply:
  • Only the BBT_POINT type is supported
  • Size and appearance of each billboard is controlled by the material (Pass::setPointSize, Pass::setPointSizeAttenuation, Pass::setPointSpritesEnabled)
  • Per-billboard size is not supported (stems from the above)
  • Per-billboard rotation is not supported, this can only be controlled through texture unit rotation
  • Only BBO_CENTER origin is supported
  • Per-billboard texture coordinates are not supported
You will almost certainly want to enable in your material pass both point attenuation and point sprites if you use this option.
Parameters:
enabled True to enable point rendering, false otherwise

virtual void Ogre::Renderable::setPolygonModeOverrideable (  bool  override  )  [virtual, inherited]
 

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:
override true means that a lower camera detail will override this renderables detail level, false means it won't.

Definition at line 231 of file OgreRenderable.h.

virtual void Ogre::BillboardSet::setPoolSize (  unsigned int  size  )  [virtual]
 

Adjusts the size of the pool of billboards available in this set.

Remarks:
See the BillboardSet::setAutoextend method for full details of the billboard pool. This method adjusts the preallocated size of the pool. If you try to reduce the size of the pool, the set has the option of ignoring you if too many billboards are already in use. Bear in mind that calling this method will incur significant construction / destruction calls so should be avoided in time-critical code. The same goes for auto-extension, try to avoid it by estimating the pool size correctly up-front.
Parameters:
size The new size for the pool.

virtual void Ogre::MovableObject::setQueryFlags (  uint32  flags  )  [virtual, inherited]
 

Sets the query flags for this object.

Remarks:
When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

References Ogre::uint32.

virtual void Ogre::MovableObject::setRenderingDistance (  Real  dist  )  [virtual, inherited]
 

Sets the distance at which the object is no longer rendered.

Parameters:
dist Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 202 of file OgreMovableObject.h.

References Ogre::Real.

virtual void Ogre::MovableObject::setRenderQueueGroup (  uint8  queueID  )  [virtual, inherited]
 

Sets the render queue group this entity will be rendered through.

Remarks:
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.
See RenderQueue for more details.
Parameters:
queueID Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual void Ogre::BillboardSet::setSortingEnabled (  bool  sortenable  )  [virtual]
 

Enables sorting for this BillboardSet.

(default: off)

Parameters:
sortenable true to sort the billboards according to their distance to the camera

virtual void Ogre::BillboardSet::setTextureCoords (  Ogre::FloatRect const *  coords,
uint16  numCoords
)  [virtual]
 

BillboardSet can use custom texture coordinates for various billboards.

This is useful for selecting one of many particle images out of a tiled texture sheet, or doing flipbook animation within a single texture.

The generic functionality is setTextureCoords(), which will copy the texture coordinate rects you supply into internal storage for the billboard set. If your texture sheet is a square grid, you can also use setTextureStacksAndSlices() for more convenience, which will construct the set of texture coordinates for you.
When a Billboard is created, it can be assigned a texture coordinate set from within the sets you specify (that set can also be re-specified later). When drawn, the billboard will use those texture coordinates, rather than the full 0-1 range.
Parameters:
coords is a vector of texture coordinates (in UV space) to choose from for each billboard created in the set.
numCoords is how many such coordinate rectangles there are to choose from.
Remarks:
Set 'coords' to 0 and/or 'numCoords' to 0 to reset the texture coord rects to the initial set of a single rectangle spanning 0 through 1 in both U and V (i e, the entire texture).
See also:
BillboardSet::setTextureStacksAndSlices() Billboard::setTexcoordIndex()

virtual void Ogre::BillboardSet::setTextureStacksAndSlices (  uchar  stacks,
uchar  slices
)  [virtual]
 

setTextureStacksAndSlices() will generate texture coordinate rects as if the texture for the billboard set contained 'stacks' rows of 'slices' images each, all equal size.

Thus, if the texture size is 512x512 and 'stacks' is 4 and 'slices' is 8, each sub-rectangle of the texture would be 128 texels tall and 64 texels wide.

Remarks:
This function is short-hand for creating a regular set and calling setTextureCoords() yourself. The numbering used for Billboard::setTexcoordIndex() counts first across, then down, so top-left is 0, the one to the right of that is 1, and the lower-right is stacks*slices-1.

BillboardSet::setTextureCoords()

virtual void Ogre::BillboardSet::setUseAccurateFacing (  bool  acc  )  [virtual]
 

Sets whether or not billboards should use an 'accurate' facing model based on the vector from each billboard to the camera, rather than an optimised version using just the camera direction.

Remarks:
By default, the axes for all billboards are calulated using the camera's view direction, not the vector from the camera position to the billboard. The former is faster, and most of the time the difference is not noticeable. However for some purposes (e.g. very large, static billboards) the changing billboard orientation when rotating the camera can be off putting, therefore you can enable this option to use a more expensive, but more accurate version.
Parameters:
acc True to use the slower but more accurate model. Default is false.

Definition at line 693 of file OgreBillboardSet.h.

virtual void Ogre::MovableObject::setUserAny (  const Any &  anything  )  [virtual, inherited]
 

Sets any kind of user value on this object.

Remarks:
This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.
Note:
This value is shared with setUserObject so don't use both!

Definition at line 232 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject (  UserDefinedObject *  obj  )  [virtual, inherited]
 

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 216 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags (  uint32  flags  )  [virtual, inherited]
 

Sets the visiblity flags for this object.

Remarks:
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 292 of file OgreMovableObject.h.

References Ogre::uint32.

virtual void Ogre::MovableObject::setVisible (  bool  visible  )  [virtual, inherited]
 

Tells this object whether to be visible or not, if it has a renderable component.

Note:
An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing (  EdgeData *  edgeData,
const Vector4 &  lightPos
)  [protected, virtual, inherited]
 

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:
edgeData The edge information to update
lightPos 4D vector representing the light, a directional light has w=0.0

virtual bool Ogre::Renderable::useIdentityProjection (  void   )  const [virtual, inherited]
 

Returns whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.

Definition at line 114 of file OgreRenderable.h.

virtual bool Ogre::Renderable::useIdentityView (  void   )  const [virtual, inherited]
 

Returns whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.
