rtpp — raytrace an mged model, writing a GIFT-style Pretty Picture file
operates on the indicated
in the input
and produces a GIFT-style "pretty picture" format file
on standard output.
The orientation of the rays to be fired may be specified by
options, in which case the model will be autosized, and the grid
will be centered on the centroid of the model, with ray spacing
chosen to span the entire set of
option, a transformation matrix may be provided on standard input
which maps model-space to view-space.
In this case, the grid ranges from -1.0 <= X,Y <= +1.0 in view space,
with the size of the grid (number of pixels) specified with

The rtpp program is a simple front-end to librt(3) which is most useful when used with mged(1). In order to display a pretty-picture file, the programs pp-ik(1) and pp-fb(1) are used.

Numerous error conditions are possible. Descriptive messages are printed on standard error (file descriptor 2).
Most deficiencies observed while using the rtpp program are usually with the librt(3) package instead.
