D3DRMCOMBINE_
Specifies how to combine two matrices.
- D3DRMCOMBINE_REPLACE
- The supplied matrix replaces the frame's current matrix.
- D3DRMCOMBINE_BEFORE
- The supplied matrix is multiplied with the frame's current matrix and precedes the current matrix in the calculation.
- D3DRMCOMBINE_AFTER
- The supplied matrix is multiplied with the frame's current matrix and follows the current matrix in the calculation.
The order of the supplied and current matrices when they are multiplied together is important because matrix multiplication is not commutative.
