Hi Roger! Just wanted to let you know that your postings have successfully got me to a working playground and communicating with the PiTrex.
One issue that I continue to think about involving vector rendering is z-buffering (yes, that is probably not the right term in this case since this isn't a raster-based render). I have been really trying to think of a way to cull lines that can't be seen. From my own experience, the actual drawing of vectors is the most time-consuming part of each cycle. But, since we are now using a much faster processor, it should be possible to remove unwanted lines before rendering. Back-face culling is straight forward enough, but removing obscured front-facing vectors seems to be the challenge.

Any thoughts?
