Detailed Description

Class used to pass geometry/rendering data to the renderer. Note that the GetBoundingBox function must always return a valid bounding box, so that the renderer can optimize properly. The TCountedRenderable supplies one kind of geometry (I3DShRenderable::EType) to the renderer, along with flags describing how to render the geometry.

Member Function Documentation

virtual uint32 MCCOMAPI TCountedRenderable::AddRef (   )  [inline, virtual]

Increments the reference count of the object Reimplemented from TMCSMPCountedObject.

virtual void MCCOMAPI TCountedRenderable::GetBoundingBox (  TBBox3D &  bbox  )  [virtual]

Returns the bounding box of the renderable in local coordinates (for triangle meshes). Parameters: bb  The bounding box that is returned. Implements I3DShRenderable. Reimplemented in TRenderableHelper, and TSimpleShapeRenderable.

virtual MCCOMErr MCCOMAPI TCountedRenderable::GetFlatennedTexturesAsync (  uint32  uvSpaceID, UVMaps &  maps, TextureAvailableProc  proc, void *  privData, TMCRealRect *  range = nil )  const [virtual]

Calculates a set of texture maps that approximates the shading on the instance. Parameters: uvSpaceID  The shading domain index. maps  The maps that are returned. proc  A callback function called when the texture is available. privData  Data passed by the callback. range  A rectangle in the texture coordinates. (NULL if the whole uvspace is required). Implements I3DShRenderable.

virtual MCCOMErr MCCOMAPI TCountedRenderable::GetFMesh (  real  lod, FacetMesh **  amesh )  [virtual]

Returns a pointer to the triangle mesh contained in this renderable. Returns NULL if the renderable is not a triangle mesh (see GetGeometryType()). Parameters: lod  The lod that is requested. amesh  A pointer to the mesh that is returned. Implements I3DShRenderable. Reimplemented in TSimpleShapeRenderable.

virtual I3DShRenderable::EType MCCOMAPI TCountedRenderable::GetGeometryType (   )  const [virtual]

Returns the type of geometry that should be rendered (points, segments or triangles...) Implements I3DShRenderable. Reimplemented in TRenderableHelper, TPointMeshRenderable, TSegmentMeshRenderable, and TSimpleShapeRenderable.

virtual MCCOMErr MCCOMAPI TCountedRenderable::GetInstance (  I3DShInstance **  instance  )  [virtual]

Returns a pointer to the instance that corresponds to the renderable. Note that it can be NULL if the renderable has no instance Parameters: instance  A pointer to the instance. Implements I3DShRenderable.

virtual const TPointMesh* MCCOMAPI TCountedRenderable::GetPointMesh (   )  const [virtual]

Returns a pointer to the point mesh contained in this renderable. Returns NULL if the renderable is not a point mesh (see GetGeometryType()). Implements I3DShRenderable. Reimplemented in TPointMeshRenderable, and TSimpleShapeRenderable.

virtual TRenderableFlags MCCOMAPI TCountedRenderable::GetRenderableFlags (  void   )  const [virtual]

Returns the flags associated with this renderable. See TRenderableFlags for more info. Implements I3DShRenderable. Reimplemented in TRenderableHelper, and TSimpleShapeRenderable.

virtual const TSegmentMesh* MCCOMAPI TCountedRenderable::GetSegmentMesh (   )  const [virtual]

Returns a pointer to the segment mesh contained in this renderable. Returns NULL if the renderable is not a segment mesh (see GetGeometryType()). Implements I3DShRenderable. Reimplemented in TSegmentMeshRenderable, and TSimpleShapeRenderable.

virtual MCCOMErr MCCOMAPI TCountedRenderable::GetShadingApproximation (  TShadingApproximation &  shadingApprox, uint32  uvSpaceID )  const [virtual]

Returns an approximation of the shading that can be used for interactive rendering. Parameters: shadingApprox  The color of the shader. uvSpaceID  The UVSpaceID for which the approximation is required. Implements I3DShRenderable. Reimplemented in TRenderableHelper, and TSimpleShapeRenderable.

virtual uint32 MCCOMAPI TCountedRenderable::GetUVSpaceCount (   )  [virtual]

Returns the number of shading domaine (uv space) on the primitive. Implements I3DShRenderable.

virtual MCCOMErr MCCOMAPI TCountedRenderable::QueryInterface (  const MCIID &  riid, void **  ppvObj )  [virtual]

Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found. Parameters: riid  GUID of the interface ppvObj  A pointer to the pointer being returned. Reimplemented from TMCSMPCountedObject.

virtual uint32 MCCOMAPI TCountedRenderable::Release (   )  [inline, virtual]

Decrements the reference count of the object. If the reference count reaches zero, the object is destroyed. Reimplemented from TMCSMPCountedObject.

virtual MCCOMErr MCCOMAPI TCountedRenderable::SetRenderableFlags (  const TRenderableFlags  flags  )  [virtual]

Sets the flags associated with this renderable. Parameters: flags  The flags. Implements I3DShRenderable. Reimplemented in TSimpleShapeRenderable.
