D3DXBONECOMBINATION Structure

Describes a subset of the mesh that has the same attribute and bone combination.

Syntax

typedef struct _D3DXBONECOMBINATION {
    DWORD AttribId;
    DWORD FaceStart;
    DWORD FaceCount;
    DWORD VertexStart;
    DWORD VertexCount;
    DWORD *BoneId;
} D3DXBONECOMBINATION, *LPD3DXBONECOMBINATION;

Members

AttribId

Attribute table identifier.

FaceStart

Starting face.

FaceCount

Face count.

VertexStart

Starting vertex.

VertexCount

Vertex count.

BoneId

Pointer to an array of values that identify each of the bones that can be drawn in a single drawing call. Note that the array can be of variable length to accommodate variable length bone combinations of ID3DXSkinInfo::ConvertToIndexedBlendedMesh.

The size of the array varies based on the type of mesh generated. A non-indexed mesh array size is equal to the number of weights per vertex. An indexed mesh array size is equal to the number of bone matrix palette entries.

Remarks

The subset of the mesh described by D3DXBONECOMBINATION can be rendered in a single drawing call.
