POLY_TRANS Function
Returns a list of 3D points transformed by a 4-by-4 transformation matrix.
Usage
result = POLY_TRANS(points, trans)
Input Parameters
points — A (3, n) array of points (or vertices) to transform.
trans — A (4, 4) array to transform the points with.
Returned Value
result — A list of 3D points transformed by a 4-by-4 transformation matrix.
Keywords
None.
Discussion
You can use the T3D, CENTER_VIEW, SET_VIEW3D, and VIEWER procedures to build the transformation matrix. The 4-by-4 matrix most often used is the system viewing matrix !P.T. For more information, see the PV‑WAVE User’s Guide.
