Detailed Description

Allows the rendering of a chain of connected billboards.

Remarks:: A billboard chain operates much like a traditional billboard, ie its segments always face the camera; the difference being that instead of a set of disconnected quads, the elements in this class are connected together in a chain which must always stay in a continuous strip. This kind of effect is useful for creating effects such as trails, beams, lightning effects, etc.

: A single instance of this class can actually render multiple separate chain segments in a single render operation, provided they all use the same material. To clarify the terminology: a 'segment' is a separate sub-part of the chain with its own start and end (called the 'head' and the 'tail'. An 'element' is a single position / colour / texcoord entry in a segment. You can add items to the head of a chain, and remove them from the tail, very efficiently. Each segment has a max size, and if adding an element to the segment would exceed this size, the tail element is automatically removed and re-used as the new item on the head.

: This class has no auto-updating features to do things like alter the colour of the elements or to automatically add / remove elements over time - you have to do all this yourself as a user of the class. Subclasses can however be used to provide this kind of behaviour automatically.

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

Parameters:

edgeData The edge information to use

indexBuffer The buffer into which to write data into; current contents are assumed to be discardable.

light The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing

shadowRenderables A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.

flags Additional controller flags, see ShadowRenderableFlags

Remarks:
Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

const MaterialPtr& Ogre::BillboardChain::getMaterial ( void ) const [virtual]

Retrieves a weak reference to the material this renderable object uses.

Remarks:
Note that the Renderable also has the option to override the getTechnique method to specify a particular Technique to use instead of the best one available.

Implements Ogre::Renderable.

Definition at line 120 of file OgreBillboardChain.h.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void ) const [virtual, inherited]

Returns the number of world transform matrices this renderable requires.

Remarks:
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

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

virtual const Real* Ogre::BillboardChain::getOtherTextureCoordRange ( void ) const [virtual]

Get the range of the texture coordinates generated across the width of the chain elements.

Definition at line 163 of file OgreBillboardChain.h.
References Ogre::Real.

virtual Node* Ogre::MovableObject::getParentNode ( void ) const [virtual, inherited]

Returns the node to which this object is attached.

Remarks:
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode ( void ) const [virtual, inherited]

Returns the scene node to which this object is attached.

Remarks:
A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

Real Ogre::BillboardChain::getSquaredViewDepth ( const Camera * cam ) const [virtual]

Returns the camera-relative squared depth of this renderable.

Remarks:
Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

virtual Technique* Ogre::Renderable::getTechnique ( void ) const [virtual, inherited]

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:
This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.
Definition at line 69 of file OgreRenderable.h.

virtual TexCoordDirection Ogre::BillboardChain::getTextureCoordDirection ( void ) [virtual]

Gets the direction in which texture coords specified on each element are deemed to run.

Definition at line 152 of file OgreBillboardChain.h.

virtual uint32 Ogre::MovableObject::getTypeFlags ( void ) const [virtual, inherited]

Get the 'type flags' for this MovableObject.

Remarks:
A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::Light, Ogre::ParticleSystem, Ogre::StaticGeometry::Region, and Ogre::TerrainRenderable.

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

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity.

const Quaternion& Ogre::BillboardChain::getWorldOrientation ( void ) const [virtual]

Gets the worldspace orientation of this renderable; this is used in order to more efficiently update parameters to vertex & fragment programs, since inverting Quaterion and Vector in order to derive object-space positions / directions for cameras and lights is much more efficient than inverting a complete 4x4 matrix, and also eliminates problems introduced by scaling.

Implements Ogre::Renderable.

const Vector3& Ogre::BillboardChain::getWorldPosition ( void ) const [virtual]

Gets the worldspace orientation of this renderable; this is used in order to more efficiently update parameters to vertex & fragment programs, since inverting Quaterion and Vector in order to derive object-space positions / directions for cameras and lights is much more efficient than inverting a complete 4x4 matrix, and also eliminates problems introduced by scaling.

Implements Ogre::Renderable.

void Ogre::BillboardChain::getWorldTransforms ( Matrix4 * ) const [virtual]

Gets the world transform matrix / matrices for this renderable object.

Remarks:
If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

This method will populate xform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Implements Ogre::Renderable.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary ( StringVector & vec ) const [protected, virtual, inherited]

Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters.

Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene ( void ) const [virtual, inherited]

virtual bool Ogre::MovableObject::isVisible ( void ) const [virtual, inherited]

Returns whether or not this object is supposed to be visible or not.

Remarks:
Takes into account both upper rendering distance and visible flag.

Definition at line 300 of file OgreMovableObject.h.
References Ogre::uint32.

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.

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.

Reimplemented in Ogre::RibbonTrail.

virtual void Ogre::BillboardChain::setNumberOfChains ( size_t numChains ) [virtual]

Reimplemented in Ogre::RibbonTrail.

virtual void Ogre::BillboardChain::setOtherTextureCoordRange ( Real start,

Real end

) [virtual]

Set the range of the texture coordinates generated across the width of the chain elements.

Parameters:

start Start coordinate, default 0.0

end End coordinate, default 1.0

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::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.

Definition at line 264 of file OgreMovableObject.h.
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::BillboardChain::setTextureCoordDirection ( TexCoordDirection dir ) [virtual]

Sets the direction in which texture coords specified on each element are deemed to run along the length of the chain.

Parameters:

dir The direction, default is TCD_U.

virtual void Ogre::BillboardChain::setupBuffers ( void ) [protected, virtual]

virtual void Ogre::BillboardChain::setupVertexDeclaration ( void ) [protected, virtual]

Setup vertex declaration.

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::BillboardChain::setUseTextureCoords ( bool use ) [virtual]

Sets whether texture coordinate information should be included in the final buffers generated.

Note:
You must use either texture coordinates or vertex colour since the vertices have no normals and without one of these there is no source of colour for the vertices.

virtual void Ogre::BillboardChain::setUseVertexColours ( bool use ) [virtual]

Sets whether vertex colour information should be included in the final buffers generated.

Note:
You must use either texture coordinates or vertex colour since the vertices have no normals and without one of these there is no source of colour for the vertices.

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::BillboardChain::updateBoundingBox ( void ) const [protected, virtual]

virtual void Ogre::BillboardChain::updateChainElement ( size_t chainIndex,

size_t elementIndex,

const Element & billboardChainElement

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 void Ogre::BillboardChain::updateIndexBuffer ( void ) [protected, virtual]

Update the contents of the index buffer.

virtual void Ogre::BillboardChain::updateVertexBuffer ( Camera * cam ) [protected, virtual]

Update the contents of the vertex buffer.

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.
