void vl::PatchParameter::setPatchVertices ( int vertices ) [inline]

Specifies the number of vertices that will be used to make up a single patch primitive.

Patch primitives are consumed by the tessellation control shader (if present) and subsequently used for tessellation. When primitives are specified using glDrawArrays or a similar function, each patch will be made from vertices control points, each represented by a vertex taken from the enabeld vertex arrays. vertices must be greater than zero, and less than or equal to the value of GL_MAX_PATCH_VERTICES.
