Utility function for stencil splicing for local point stencils.

Parameters
refinerThe TopologyRefiner containing the topology
baseStencilTableInput StencilTable for refined vertices
localPointStencilTableStencilTable for the change of basis patch points.
factorizeIf factorize is set to true, endcap stencils will be factorized with supporting vertices from baseStencil table so that the endcap points can be computed directly from control vertices.

Utility function for stencil splicing for local point varying stencils.

Parameters
refinerThe TopologyRefiner containing the topology
baseStencilTableInput StencilTable for refined vertices
localPointStencilTableStencilTable for the change of basis patch points.
factorizeIf factorize is set to true, endcap stencils will be factorized with supporting vertices from baseStencil table so that the endcap points can be computed directly from control vertices.
template<typename REAL >
StencilTableReal< REAL > const * OpenSubdiv::v3_4_3::Far::StencilTableFactoryReal< REAL >::Create ( TopologyRefiner const &  refiner,
Options  options = Options() 
)
static

Instantiates StencilTable from TopologyRefiner that have been refined uniformly or adaptively.

Note
The factory only creates stencils for vertices that have already been refined in the TopologyRefiner. Use RefineUniform() or RefineAdaptive() before constructing the stencils.
Parameters
refinerThe TopologyRefiner containing the topology
optionsOptions controlling the creation of the table

template<typename REAL>
StencilTableReal< REAL > const * OpenSubdiv::v3_4_3::Far::StencilTableFactoryReal< REAL >::Create ( int  numTables,
StencilTableReal< REAL > const **  tables 
)
static

Instantiates StencilTable by concatenating an array of existing stencil tables.

Note
This factory checks that the stencil tables point to the same set of supporting control vertices - no re-indexing is done. GetNumControlVertices() must return the same value for all input tables.
Parameters
numTablesNumber of input StencilTables
tablesArray of input StencilTables
