My last animation from ray tracing the heart had some bumps and the corners of both lobes were sliced by the bounding box. I've just finished doing corrections to rt_hrt_bbox() and rt_hrt_norm() and  ray tracing yields even better results.

Please download and watch the video I have uploaded to you tube live on http://youtu.be/EpdBJIIe31U.

 

That looks fantastic!  Basically says that you got shot() working (and amazingly our root solver is stable even where the surface is discontinuous (in the top and bottom pinches).  That's impressive on multiple levels.

Apart from some few bumpy corners ( which will be eventually fixed with rt_hrt_plot() ), I think the heart primitive is doing great.

It is looking great.  Looks like there's some problems in norm(), but the basic shape hit points are looking really good from that video.  Note that changes in plot() are not going to affect the ray tracing results.  They only describe what simple (wireframe) elements are displayed when you run the 'draw' command in mged.  The visual discontinuities in the middle of the heart are probably issues in norm().

Cheers!
