D3DRMCOMBINE_

Specifies how to combine two matrices.

D3DRMCOMBINE_AFTER

The supplied matrix is multiplied with the frame's current matrix and follows the current matrix in the calculation.

D3DRMCOMBINE_BEFORE

The supplied matrix is multiplied with the frame's current matrix and precedes the current matrix in the calculation.

D3DRMCOMBINE_REPLACE

The supplied matrix replaces the frame's current matrix.

The order of the supplied and current matrices when they are multiplied together is important because matrix multiplication is not commutative.
