hi,

I'm working on a macro which, given an object positioned at origin, a vertical
resolution, and a frame_number N, returns the Nth "slice", ie the intersection
of object and a (transparent) box.

when I scan a simple (red) sphere[*], the first few frames, and the last few
look exactly as expected, however, on the frames between more and more
information is missing, up to 100% in the middle.

puzzled, and no idea what the problem might be.

I've posted a zip with a set of example frames in povray.binaries.misc.

[*] lit by eight light at corners of imaginary cube, recorded with orthographic
camera positioned above.


regards, jr.
