The following methods are redirected from the particle object level to a particular ActionList.

The first parameter is a particle container of the ActionList. Returns 0 if the action doesn't render in all frames for any reason, for example a non-animated parameter prevents render.

Parameters:

pCont,:	particle container to render particles from
time,:	current frame to render particles at. It's supposed that the container has been already updated to satisfy this moment
pSystem,:	master particle system shell
inode,:	INode of the particle group
view,:	View as of the GeomObject::GetRenderMesh(...) method
needDelete,:	boolean as of the GeomObject::GetRenderMesh(...) method

{ return(1); }

If an object creates different meshes depending on the particular instance (view-dependent) it should return 1.

{ return 0; }

GetRenderMesh should be implemented by all renderable GeomObjects.

Set needDelete to TRUE if the render should delete the mesh, FALSE otherwise. Primitives that already have a mesh cached can just return a pointer to it (and set needDelete = FALSE).

Objects may now supply multiple render meshes.

If this function returns a positive number, then GetMultipleRenderMesh and GetMultipleRenderMeshTM will be called for each mesh, instead of calling GetRenderMesh.

{ return 0; } // 0 indicates multiple meshes not supported.

For multiple render meshes, this method must be implemented.

Set needDelete to TRUE if the render should delete the mesh, FALSE otherwise. meshNumber specifies which of the multiplie meshes is being asked for.

{ return NULL; }

For multiple render meshes, this method must be implemented.

meshTM should be returned with the transform defining the offset of the particular mesh in object space. meshTMValid should contain the validity interval of meshTM
