GT_Size GT_OSDTopology::coarseFaceCount ( ) const

inline

Return specific information about the coarse mesh (i.e. level 0)

GT_Size GT_OSDTopology::coarsePointCount ( ) const

inline

Return specific information about the coarse mesh (i.e. level 0)

GT_Size GT_OSDTopology::coarseVertexCount ( ) const

inline

Return specific information about the coarse mesh (i.e. level 0)

Definition at line 240 of file GT_OSD3.h.

GT_Size GT_OSDTopology::coarseVertexCount ( GT_Size face_index ) const

Return specific information about the coarse mesh (i.e. level 0)

bool GT_OSDTopology::create	(	const GT_PrimPolygonMesh &	mesh,
		const GT_OSDOptions &	options
	)

Create the topology for the given polygonal hull and options. Note that if the mesh is a GT_PrimSubdivisionMesh, crease weights will be picked up from the tags on the primitive.

GT_PrimitiveHandle GT_OSDTopology::createMesh	(	int	level,
		const GT_AttributeListHandle &	point,
		const GT_AttributeListHandle &	vertex,
		const GT_AttributeListHandle &	uniform,
		const GT_AttributeListHandle &	detail,
		const GT_FaceSetMapPtr &	fsets = `GT_FaceSetMapPtr()`
	)		const

Create a polygon mesh for a given level.

void GT_OSDTopology::dump ( ) const

Debug - dump the topology out

void GT_OSDTopology::dump ( UT_JSONWriter & w ) const

Debug - dump the topology out

const LevelInfo& GT_OSDTopology::lastLevel ( ) const

inline

Definition at line 230 of file GT_OSD3.h.

exint GT_OSDTopology::levelCount ( ) const

inline

Number of levels in refinement (note this is the max level + 1)

Definition at line 218 of file GT_OSD3.h.

const LevelInfo& GT_OSDTopology::levelInfo ( int level ) const

inline

Access to the level information for a given refinement level This returns the number of vertices, face-varying vertices, faces, etc. for each level. Level 0 is the "coarse" mesh.

GetNumVertices() - Number of shared points (i.e. Houdini points)
GetNumFaces() - Number of faces
GetNumEdges() - Number of edges
GetNumFaceVertices() - Number of face varying (i.e. Houdini vertices)

UT_IntArray GT_OSDTopology::ptexToFaceMap ( ) const

Build and return ptex to faceid mapping.

const TopologyRefiner* GT_OSDTopology::refiner ( ) const

inline

Access to the refiner.
