Description

PTR3 creates a three-dimensional (4 x 4) homogeneous transformation matrix that performs the translation as defined by the specified translation vector.  The returned matrix can be passed to functions that require transformation matrices as input, such as the PSLMT3, PSGMT3, and PCOM3 functions.  To store a matrix in a structure element, you must pass it to the PSGMT3 or PSLMT3 function.
