PatchDescriptor()
Default constructor.
bool IsAdaptive() const
Returns true if the type is an adaptive patch.
bool operator==(PatchDescriptor const other) const
True if the descriptors are identical.
static short GetGregoryBasisPatchSize()
Number of control vertices of Gregory patch basis (20)
static short GetRegularPatchSize()
Number of control vertices of Regular Patches in table.
bilinear triangles-only mesh
static short GetGregoryPatchSize()
Number of control vertices of Gregory (and Gregory Boundary) Patches in table.
SchemeType
Enumerated type for all subdivisions schemes supported by OpenSubdiv.
Vtr::ConstArray< PatchDescriptor > ConstPatchDescriptorArray
bool operator<(PatchDescriptor const other) const
Allows ordering of patches by type.
short GetNumControlVertices() const
Returns the number of control vertices expected for a patch of the type described.
