Detailed Description

A vtGeode is a "Geometry Node "which can contain any number of visible vtMesh objects.

: A vtGeode also manages a set of Materials (vtMaterial). Each contained mesh is assigned one of these materials, by index.

: This separation (Group/Mesh) provides the useful ability to define a vtMesh once in memory, and have multiple vtGeode nodes which contain it, which permits a large number of visual instances (each with potentially different material and transform) with very little memory cost.

Member Function Documentation

Add a mesh to this geometry.

Parameters

pMesh	The mesh to add
iMatIdx	The material index for this mesh, which is an index into the material array of the geometry.

Add a text mesh to this geometry.

Parameters

pMesh	The mesh to add
iMatIdx	The material index for this mesh, which is an index into the material array of the geometry.
bOutline	true to put a dark outline around the text for contrast.

vtMesh * vtGeode::GetMesh ( int i ) const

Return a contained vtMesh by index.

vtTextMesh * vtGeode::GetTextMesh ( int i ) const

Return a contained vtTextMesh by index.

uint vtGeode::NumMeshes ( ) const

Return the number of contained meshes.

void vtGeode::RemoveAllMeshes ( )

Remove all meshes from the geomtry. They are refcounted so there is no need to worry about freeing them.

void vtGeode::RemoveMesh ( vtMesh * pMesh )

Remove a mesh from the geomtry. Has no effect if the mesh is not currently contained.
