m |
New rotation matrix. m may be an Mtx or an MtxPtr. |
|---|---|
| axis | Pointer to a Vec containing the components of the rotation axis. axis may also be a Point3dPtr. The (x,y,z) members of axis correspond to the (x,y,z) components of the rotation axis. For example, (1,0,0) indicates a rotation about the X axis. axis does not have to be a unit vector. |
| rad | Rotation angle in radians. Counter-clockwise rotations are positive. |
None.
Sets the matrix to be rotated around the axis having the (x,y,z) component specified by axis. Counter-clockwise rotations are positive.
During a debug build, MTXRotAxisRad is interpreted as C_MTXRotAxisRad, which is a normal C language version. During a non-debug build for a Broadway processor, the paired-singles equivalent of this function, PSMTXRotAxisRad, will be automatically substituted. You can also call C_MTXRotAxisRad and PSMTXRotAxisRad explicitly.
