Title: POINT on NURBS surface
Post by: ribarm on March 26, 2019, 06:28:33 AM
Hi guys...
I need some help/advice... I want to acquire one point data (coordinates) of point that lie on NURBS surface... I don't want to use IMPRINT or something like that, I just need this as fast as possible - so no sending rays of lines for checking... Only one single point on surface is all that I want, and please with LISP (no VB(A), C, C++, C#)...
Thanks, M.R.

Not 100% sure about reliability, but according to my testings, it should work... If someone has some suggestion, I am open to hear it, thanks...

I've rechecked it and now it fails to get at least 1 point... Situation is that NURBS is planar and parallel to either WCS plane or FRONT, LEFT, RIGHT, BACK, TOP, BOTTOM of WCS - NURBS is RECTANGULAR shape... So I need more opinions and revision of code, thanks...
