@brief Return the number of indices assigned to each facet

@brief Return the number of elements between each facet

Return the number of subfaces in the path

Number of edges in the mesh

\brief Returns the total number of edges in all levels

trivial accessors

Returns the GL texture buffer containing the patch control vertices

Generates the version definition needed by the glsl shaders based on the opengl string

\brief Returns the size of the stencil as a pointer

interfaces needed for CLComputeKernel

interfaces needed for CudaCompute

interfaces needed for GLSLComputeKernel

interfaces needed for GLSLTransformFeedbackKernel

Return a subface element in the path

\brief Get triangle subdivision weights rule (Catmark scheme only !)

\brief Returns the log2 value of the u parameter at the first corner of the patch

Return the uniform index of the face. This is different from the ID because it may be shared with other faces

\brief Returns the log2 value of the v parameter at the first corner of the patch

Returns the GL texture buffer containing the varying control vertices

\brief Access the local indices of a vertex with respect to its incident faces

Queries for multiple VertexTags combined into one:

Methods to test for and resolve unordered corners of the face:

Coarse faces are the top level faces of a mesh. This will be set by mesh->Finish()

Check the usage counter on the vertex

\brief True if the parent base face is a non-quad

XXXX manuelk this should be optimized further by using SIMD - considering OMP is somewhat obsolete - this is probably not worth it.

Deprecated -- prefer use of OsdEvaluatePatchBasis() and OsdEvaluatePatchBasisNormalized() methods.

namespace { Cubic BSpline curve basis evaluation:

Remove the reference to subdivided vertex

sets the child in "quadrant" to point to node or patch of the given index
