/* This function creates atlases for meshes. There are two modes of operation,
* either based on the number of charts, or the maximum allowed stretch. If the
* maximum allowed stretch is 0, then each triangle will likely be in its own
* chart.
*/
/*
* The parameters are as follows:
* pMesh - Input mesh to calculate an atlas for. This must have a position
* channel and at least a 2-d texture channel.
* uMaxChartNumber - The maximum number of charts required for the atlas.
* If this is 0, it will be parameterized based solely on
* stretch.
* fMaxStretch - The maximum amount of stretch, if 0, no stretching is allowed,
* if 1, then any amount of stretching is allowed.
* uWidth - The width of the texture the atlas will be used on.
* uHeight - The height of the texture the atlas will be used on.
* fGutter - The minimum distance, in texels between two charts on the atlas.
* this gets scaled by the width, so if fGutter is 2.5, and it is
* used on a 512x512 texture, then the minimum distance will be
* 2.5 / 512 in u-v space.
* dwTextureIndex - Specifies which texture coordinate to write to in the
* output mesh (which is cloned from the input mesh). Useful
* if your vertex has multiple texture coordinates.
* pdwAdjacency - a pointer to an array with 3 DWORDs per face, indicating
* which triangles are adjacent to each other.
* pdwFalseEdgeAdjacency - a pointer to an array with 3 DWORDS per face, indicating
* at each face, whether an edge is a false edge or not (using
* the same ordering as the adjacency data structure). If this
* is NULL, then it is assumed that there are no false edges. If
* not NULL, then a non-false edge is indicated by -1 and a false
* edge is indicated by any other value (it is not required, but
* it may be useful for the caller to use the original adjacency
* value). This allows you to parameterize a mesh of quads, and
* the edges down the middle of each quad will not be cut when
* parameterizing the mesh.
* pfIMTArray - a pointer to an array with 3 FLOATs per face, describing the
* integrated metric tensor for that face. This lets you control
* the way this triangle may be stretched in the atlas. The IMT
* passed in will be 3 floats (a,b,c) and specify a symmetric
* matrix (a b) that, given a vector (s,t), specifies the
* (b c)
* distance between a vector v1 and a vector v2 = v1 + (s,t) as
* sqrt((s, t) * M * (s, t)^T).
* In other words, this lets one specify the magnitude of the
* stretch in an arbitrary direction in u-v space. For example
* if a = b = c = 1, then this scales the vector (1,1) by 2, and
* the vector (1,-1) by 0. Note that this is multiplying the edge
* length by the square of the matrix, so if you want the face to
* stretch to twice its
* size with no shearing, the IMT value should be (2, 0, 2), which
* is just the identity matrix times 2.
* Note that this assumes you have an orientation for the triangle
* in some 2-D space. For D3DXUVAtlas, this space is created by
* letting S be the direction from the first to the second
* vertex, and T be the cross product between the normal and S.
*
* pStatusCallback - Since the atlas creation process can be very CPU intensive,
* this allows the programmer to specify a function to be called
* periodically, similarly to how it is done in the PRT simulation
* engine.
* fCallbackFrequency - This lets you specify how often the callback will be
* called. A decent default should be 0.0001f.
* pUserContext - a void pointer to be passed back to the callback function
* dwOptions - A combination of flags in the D3DXUVATLAS enum
* ppMeshOut - A pointer to a location to store a pointer for the newly created
* mesh.
* ppFacePartitioning - A pointer to a location to store a pointer for an array,
* one DWORD per face, giving the final partitioning
* created by the atlasing algorithm.
* ppVertexRemapArray - A pointer to a location to store a pointer for an array,
* one DWORD per vertex, giving the vertex it was copied
* from, if any vertices needed to be split.
* pfMaxStretchOut - A location to store the maximum stretch resulting from the
* atlasing algorithm.
* puNumChartsOut - A location to store the number of charts created, or if the
* maximum number of charts was too low, this gives the minimum
* number of charts needed to create an atlas.
