PatchMesh9

Defines a mesh defined by Bézier patches. The first array is a list of vertices, and the second array defines the patches for the mesh by indexing into the vertex array.

template PatchMesh9
{
    < B9EC94E1-B9A6-4251-BA18-94893F02C0EA >
    DWORD Type;
    DWORD Degree;
    DWORD Basis;
    DWORD nVertices;
    array Vector vertices[nVertices];
    DWORD nPatches;
    array Patch patches[nPatches];
    [ ... ]
} 

Where:

• Type - Patch mesh type: rectangle, triangle, or N-patch.
• Degree - Degree of the variables in the curve equation.
• Basis - Basis type of a high-order patch surface.
• nVertices - Number of vertices.
• vertices[nVertices] - Array of vertices. See Vector.
• nPatches - Number of patches.
• patches[nPatches] - Array of patches. See Patch.
• [ ... ] - Any .x file template can be used here. This makes the architecture extensible.

The patches use the vertices in the array of vertices as the control points for each patch.
