Sorry, I got kicked offline last time I responded.  Now I've looked at the latest upload, and I'm very happy.  Thank you, thank you for adding the CorrelateByIndexLists() to the .pyd.  This opens up new possibilities beyond the TDMT implementation of the point-in-tri.  :D

Yes, it is simpler.  Simple is good, particularly if the script's purpose is meant to be whaddayacall didactic.

The latest zip includes a vector_glue.c file.  Is that meant to be included?  Does it need to be placed anywhere, or is it just a glimpse into the code you're using?  I assume one can't compile from it without the .h file referenced at the top.

So... I'm off to tinker and test!  :D

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
