Detailed Description

template<typename REAL>
class OpenSubdiv::v3_4_3::Far::LimitStencilTableFactoryReal< REAL >

A specialized factory for LimitStencilTable.

The LimitStencilTableFactory creates a table of limit stencils. Limit stencils can interpolate any arbitrary location on the limit surface. The stencils will be bilinear if the surface is refined uniformly, and bicubic if feature adaptive isolation is used instead.

Surface locations are expressed as a combination of ptex face index and normalized (s,t) patch coordinates. The factory exposes the LocationArray struct as a container for these location descriptors.

Instantiates LimitStencilTable from a TopologyRefiner that has been refined either uniformly or adaptively.

Parameters
refinerThe TopologyRefiner containing the topology
locationArraysAn array of surface location descriptors (see LocationArray)
cvStencilsA StencilTable generated from the TopologyRefiner (Optional: prevents redundant instantiation of the table if available. The given table must at least contain stencils for all control points and all refined points – any stencils for local points of a PatchTable must match the PatchTable provided or internally generated)
patchTableA PatchTable generated from the TopologyRefiner (Optional: prevents redundant instantiation of the table if available. The given table must match the optional StencilTable if also provided)
optionsOptions controlling the creation of the table
