Detailed Description

A viewpoint from which the scene will be rendered.

Remarks:
OGRE renders scenes from a camera viewpoint into a buffer of some sort, normally a window or a texture (a subclass of RenderTarget). OGRE cameras support both perspective projection (the default, meaning objects get smaller the further away they are) and orthographic projection (blueprint-style, no decrease in size with distance). Each camera carries with it a style of rendering, e.g. full textured, flat shaded, wireframe), field of view, rendering distances etc, allowing you to use OGRE to create complex multi-window views if required. In addition, more than one camera can point at a single render target if required, each rendering to a subset of the target, allowing split screen and picture-in-picture views.
Cameras maintain their own aspect ratios, field of view, and frustrum, and project co-ordinates into a space measured from -1 to 1 in x and y, and 0 to 1 in z. At render time, the camera will be rendering to a Viewport which will translate these parametric co-ordinates into real screen co-ordinates. Obviously it is advisable that the viewport has the same aspect ratio as the camera to avoid distortion (unless you want it!).
Note that a Camera can be attached to a SceneNode, using the method SceneNode::attachObject. If this is done the Camera will combine it's own position/orientation settings with it's parent SceneNode. This is useful for implementing more complex Camera / object relationships i.e. having a camera attached to a world object.

Tells the Camera to contact the SceneManager to render from it's viewpoint.

Parameters:
vp The viewport to render to
includeOverlays Whether or not any overlay objects should be included

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::TerrainRenderable.

virtual void Ogre::Frustum::disableCustomNearClipPlane (  void   )  [virtual, inherited]
 

Disables any custom near clip plane.

virtual void Ogre::Frustum::disableReflection (  void   )  [virtual, inherited]
 

Disables reflection modification previously turned on with enableReflection.

virtual void Ogre::Frustum::enableCustomNearClipPlane (  const Plane &  plane  )  [virtual, inherited]
 

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks:
There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts). Whilst it is possible to use user clip planes, they are not supported on all cards, and sometimes are not hardware accelerated when they are available. Instead, where a single clip plane is involved, this technique uses a 'fudging' of the near clip plane, which is available and fast on all hardware, to perform as the arbitrary clip plane. This does change the shape of the frustum, leading to some depth buffer loss of precision, but for many of the uses of this technique that is not an issue.
Note:
This technique only works for perspective projection.
Parameters:
plane The plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

virtual void Ogre::Frustum::enableCustomNearClipPlane (  const MovablePlane *  plane  )  [virtual, inherited]
 

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks:
There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts).

This does change the shape of the frustum, leading to some depth buffer loss of precision, but for many of the uses of this technique that is not an issue.
This version of the method links to a plane, rather than requiring a by-value plane definition, and therefore you can make changes to the plane (e.g. by moving / rotating the node it is attached to) and they will automatically affect this object.
Note:
This technique only works for perspective projection.
Parameters:
plane The plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

virtual void Ogre::Frustum::enableReflection (  const MovablePlane *  p  )  [virtual, inherited]
 

Modifies this frustum so it always renders from the reflection of itself through the plane specified.

Note that this version of the method links to a plane so that changes to it are picked up automatically. It is important that this plane continues to exist whilst this object does; do not destroy the plane before the frustum.

Remarks:
This is obviously useful for performing planar reflections.

virtual void Ogre::Frustum::enableReflection (  const Plane &  p  )  [virtual, inherited]
 

Modifies this frustum so it always renders from the reflection of itself through the plane specified.

Remarks:
This is obviously useful for performing planar reflections.

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::ShadowCaster::generateShadowVolume (  EdgeData *  edgeData,

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:
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.

virtual const Matrix4& Ogre::Frustum::getStandardProjectionMatrix (  void   )  const [virtual, inherited]
 

Gets the 'standard' projection matrix for this frustum, ie the projection matrix which conforms to standard right-handed rules.

Remarks:
This differs from the rendering-API dependent getProjectionMatrix in that it always returns a right-handed projection matrix result no matter what rendering API is being used - this is required for vertex and fragment programs for example. However, the resulting depth range may still vary between render systems since D3D uses [0,1] and GL uses [-1,1], and the range must be kept the same between programmable and fixed-function pipelines.

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.

const Radian &  angle
)

virtual void Ogre::Frustum::setAspectRatio (  Real  ratio  )  [virtual, inherited]
 

Sets the aspect ratio for the frustum viewport.

Remarks:
The ratio between the x and y dimensions of the rectangular area visible through the frustum is known as aspect ratio: aspect = width / height .
The default for most fullscreen windows is 1.3333 - this is also assumed by Ogre unless you use this method to state otherwise.

void Ogre::Camera::setAutoAspectRatio (  bool  autoratio  ) 
 

If set to true a vieport that owns this frustum will be able to recalculate the aspect ratio whenever the frustum is resized.

Remarks:
You should set this to true only if the frustum / camera is used by one viewport at the same time. Otherwise the aspect ratio for other viewports may be wrong.

void Ogre::Camera::setAutoTracking (  bool  enabled,
SceneNode *  target = 0,
const Vector3 &  offset = Vector3::ZERO
) 
 

Enables / disables automatic tracking of a SceneNode.

Remarks:
If you enable auto-tracking, this Camera will automatically rotate to look at the target SceneNode every frame, no matter how it or SceneNode move. This is handy if you want a Camera to be focused on a single object or group of objects. Note that by default the Camera looks at the origin of the SceneNode, if you want to tweak this, e.g. if the object which is attached to this target node is quite big and you want to point the camera at a specific point on it, provide a vector in the 'offset' parameter and the camera's target point will be adjusted.
Parameters:
enabled If true, the Camera will track the SceneNode supplied as the next parameter (cannot be null). If false the camera will cease tracking and will remain in it's current orientation.
target Pointer to the SceneNode which this Camera will track. Make sure you don't delete this SceneNode before turning off tracking (e.g. SceneManager::clearScene will delete it so be careful of this). Can be null if and only if the enabled param is false.
offset If supplied, the camera targets this point in local space of the target node instead of the origin of the target node. Good for fine tuning the look at point.

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 236 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.

Definition at line 171 of file OgreRenderable.h.

void Ogre::Camera::setDetailLevel (  SceneDetailLevel  sd  ) 
 

Sets the level of rendering detail required from this camera.

Remarks:
Each camera is set to render at full detail by default, that is with full texturing, lighting etc. This method lets you change that behaviour, allowing you to make the camera just render a wireframe view, for example.

void Ogre::Camera::setDirection (  const Vector3 &  vec  ) 
 

Sets the camera's direction vector.

void Ogre::Camera::setDirection (  Real  x,
Real  y,
Real  z
) 
 

Sets the camera's direction vector.

Remarks:
Note that the 'up' vector for the camera will automatically be recalculated based on the current 'up' vector (i.e. the roll will remain the same).

virtual void Ogre::Frustum::setFarClipDistance (  Real  farDist  )  [virtual, inherited]
 

Sets the distance to the far clipping plane.

Remarks:
The view frustrum is a pyramid created from the frustum position and the edges of the viewport. This method sets the distance for the far end of that pyramid. Different applications need different values: e.g. a flight sim needs a much further far clipping plane than a first-person shooter. An important point here is that the larger the ratio between near and far clipping planes, the lower the accuracy of the Z-buffer used to depth-cue pixels. This is because the Z-range is limited to the size of the Z buffer (16 or 32-bit) and the max values must be spread over the gap between near and far clip planes. As it happens, you can affect the accuracy far more by altering the near distance rather than the far distance, but keep this in mind.
Parameters:
far The distance to the far clipping plane from the frustum in world coordinates.If you specify 0, this means an infinite view distance which is useful especially when projecting shadows; but be careful not to use a near distance too close.

void Ogre::Camera::setFixedYawAxis (  bool  useFixed,
const Vector3 &  fixedAxis = Vector3::UNIT_Y
) 
 

Tells the camera whether to yaw around it's own local Y axis or a fixed axis of choice.

Remarks:
This method allows you to change the yaw behaviour of the camera
  • by default, the camera yaws around a fixed Y axis. This is often what you want - for example if you're making a first-person shooter, you really don't want the yaw axis to reflect the local camera Y, because this would mean a different yaw axis if the player is looking upwards rather than when they are looking straight ahead. You can change this behaviour by calling this method, which you will want to do if you are making a completely free camera like the kind used in a flight simulator.
Parameters:
useFixed If true, the axis passed in the second parameter will always be the yaw axis no matter what the camera orientation. If false, the camera yaws around the local Y.
fixedAxis The axis to use if the first parameter is true.

virtual void Ogre::Frustum::setFOVy (  const Radian &  fovy  )  [virtual, inherited]
 

Sets the Y-dimension Field Of View (FOV) of the frustum.

Remarks:
Field Of View (FOV) is the angle made between the frustum's position, and the edges of the 'screen' onto which the scene is projected. High values (90+ degrees) result in a wide-angle, fish-eye kind of view, low values (30- degrees) in a stretched, telescopic kind of view. Typical values are between 45 and 60 degrees.
This value represents the VERTICAL field-of-view. The horizontal field of view is calculated from this depending on the dimensions of the viewport (they will only be the same if the viewport is square).
Note:
Setting the FOV overrides the value supplied for frustum::setNearClipPlane.

void Ogre::Camera::setLodBias (  Real  factor = 1.0  ) 
 

Sets the level-of-detail factor for this Camera.

Remarks:
This method can be used to influence the overall level of detail of the scenes rendered using this camera. Various elements of the scene have level-of-detail reductions to improve rendering speed at distance; this method allows you to hint to those elements that you would like to adjust the level of detail that they would normally use (up or down).
The most common use for this method is to reduce the overall level of detail used for a secondary camera used for sub viewports like rear-view mirrors etc. Note that scene elements are at liberty to ignore this setting if they choose, this is merely a hint.
Parameters:
factor The factor to apply to the usual level of detail calculation. Higher values increase the detail, so 2.0 doubles the normal detail and 0.5 halves it.

virtual void Ogre::Frustum::setNearClipDistance (  Real  nearDist  )  [virtual, inherited]
 

Sets the position of the near clipping plane.

Remarks:
The position of the near clipping plane is the distance from the frustums position to the screen on which the world is projected. The near plane distance, combined with the field-of-view and the aspect ratio, determines the size of the viewport through which the world is viewed (in world co-ordinates). Note that this world viewport is different to a screen viewport, which has it's dimensions expressed in pixels. The frustums viewport should have the same aspect ratio as the screen viewport it renders into to avoid distortion.
Parameters:
near The distance to the near clipping plane from the frustum in world coordinates.

void Ogre::Camera::setOrientation (  const Quaternion &  q  ) 
 

Sets the camera's orientation.

void Ogre::Camera::setPosition (  const Vector3 &  vec  ) 
 

Sets the camera's position.

void Ogre::Camera::setPosition (  Real  x,
Real  y,
Real  z
) 
 

Sets the camera's position.

virtual void Ogre::Frustum::setProjectionType (  ProjectionType  pt  )  [virtual, inherited]
 

Sets the type of projection to use (orthographic or perspective).

Default is perspective.

virtual void Ogre::MovableObject::setQueryFlags (  unsigned long  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 199 of file OgreMovableObject.h.

virtual void Ogre::Renderable::setRenderDetailOverrideable (  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 235 of file OgreRenderable.h.

virtual void Ogre::MovableObject::setRenderQueueGroup (  RenderQueueGroupID  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::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 167 of file OgreMovableObject.h.

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::Camera::setWindow (  Real  Left,
Real  Top,
Real  Right,
Real  Bottom
)  [virtual]
 

Sets the viewing window inside of viewport.

Remarks:
This method can be used to set a subset of the viewport as the rendering target.
Parameters:
Left Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 0).
Top Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 0).
Right Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 1).
Bottom Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 1).

virtual void Ogre::Camera::setWindowImpl (  void   )  const [protected, virtual]
 

Do actual window setting, using parameters set in SetWindow call.

Remarks:
The method is called after projection matrix each change

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

void Ogre::Camera::updateFrustum (  void   )  const [protected, virtual]
 

Reimplemented from Ogre::Frustum.

void Ogre::Camera::updateView (  void   )  const [protected, virtual]
 

Reimplemented from Ogre::Frustum.

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.

Definition at line 124 of file OgreRenderable.h.

void Ogre::Camera::yaw (  const Radian &  angle  ) 
 

Rotates the camera anticlockwise around it's local y axis.
