m |
Source matrix to multiply. m may be either a Mtx or a MtxPtr. |
|---|---|
| src | Pointer to the source vector (Vec type) to be multiplied. src may also be a pointer to a Point3d. |
| dst | Pointer to the vector (Vec type) resulting from the multiplication (m x src). dst may also be a pointer to a Point3d. OK if src=dst. |
None.
Pre-multiplies a 3D vector or 3D point by a matrix ( m x src = dst ).
For multiplication purposes, the vector is treated as a four-element column vector with an implied fourth w coordinate of 1.
During a debug build, MTXMultVec is interpreted as C_MTXMultVec, which is a normal C language version. During a nondebug build for a Broadway processor, the paired-singles equivalent of this function, PSMTXMultVec, will be automatically substituted. You can also call each of C_MTXMultVec/PSMTXMultVec explicitly.
