Detailed Description

Describes the type of a patch.

Uniquely identifies all the different types of patches

Uniformly subdivided meshes contain bilinear patches of either QUADS or TRIANGLES
Adaptively subdivided meshes contain bicubic patches of types REGULAR, GREGORY, GREGORY_BOUNDARY, GREGORY_BASIS.

Bitfield layout :

Field	Bits	Content
