Detailed Description

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

Table of subdivision stencils.

Stencils are the most direct method of evaluation of locations on the limit of a surface. Every point of a limit surface can be computed by linearly blending a collection of coarse control vertices.

A stencil assigns a series of control vertex indices with a blending weight that corresponds to a unique parametric location of the limit surface. When the control vertices move in space, the limit location can be very efficiently recomputed simply by applying the blending weights to the series of coarse control vertices.
