Member Value Description
CatMullRom 2 An interpolating basis defines the surface so that it passes through all of the specified input vertices.
BSpline 1 Input vertices are treated as control points of a B-spline surface. In general, the generated surface does not contain the specified control vertices.
Bezier 0 Input vertices are treated as a series of Bezier patches. The number of vertices specified must be divisible by 3 + 1; portions of the mesh beyond this criterion are not rendered. Full continuity is assumed between sub-patches in the interior of the surface rendered by each call. Only the vertices at the corners of each sub-patch are guaranteed to lie on the resulting surface.

Remarks

The flags in this type specify the formulation to use in evaluating the high-order patch surface primitive during tessellation.
