Constructor & Destructor Documentation

HD_API HdMesh ( SdfPath const &  id,
SdfPath const &  instancerId = SdfPath() 
)
protected

Constructor.

instancerId, if specified, is the instancer which uses this mesh as a prototype.

Member Function Documentation

static HD_API void ConfigureRepr ( TfToken const &  reprName,
HdMeshReprDesc  desc1,
HdMeshReprDesc  desc2 = HdMeshReprDesc() 
)
static

Configure the geometric style of the mesh for a given representation.

We currently allow up to 2 descriptors for a representation. Example of when this may be useful: Drawing the outline in addition to the surface for a mesh.

HD_API TfTokenVector const& GetBuiltinPrimvarNames ( ) const
overridevirtual

Returns the names of built-in primvars, i.e.

primvars that are part of the core geometric schema for this prim.

Implements HdRprim.
