POLY_TRANS Function

Returns a list of 3D points transformed by a 4-by-4 transformation matrix.

result = POLY_TRANS(points, trans)

points A (3, n) array of points (or vertices) to transform.

trans A (4, 4) array to transform the points with.

result A list of 3D points transformed by a 4-by-4 transformation matrix.

None.

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 Chapter 6, Displaying Images, in the PV-WAVE User's Guide.

See the Example section in the description of the POLY_DEV routine.
