m |
New rotation matrix. m may be an Mtx or an MtxPtr. |
axis |
One of the major (X, Y, Z ) axes. For convenience, axisis passed in as a character, one of 'X', 'x', 'Y', 'y', 'Z', 'z' as appropriate (must include the single quotation marks). |
rad |
Rotation angle in radians. Counter-clockwise rotations are positive. |
None.
Creates a rotation matrix about one of the major (X, Y, Z ) axes. Counter-clockwise rotations are positive.
During a debug build, MTXRotRad is interpreted as C_MTXRotRad, which is a normal C language version. During a nondebug build for a Broadway processor, the paired-singles equivalent of this function, PSMTXRotAxisRad, will be automatically substituted. You can also call C_MTXRotRad or PSMTXRotRad explicitly.
