bezier triangle patch in 3D

Question

i would like a python script to draw in 3D a triangle bezier patch

this is an old problem and there must be some old script available to do this somehwere!

Thanks for any help

Answer 1

OpenGL RedBook, "Chapter 12 Evaluators and NURBS". C examples are here. But I really don't think you'll be able to use it on triangles, only on quads. If you want to go through the trouble of tesselating triangle, pick spline formula from wikipedia, and try to implement it yourself.

Answer 2

don't know what happen here but i think a post or 2 are missng since last time i check it this noon !

so to repeat my other answer

i need a python script for blender to make a bezier triangle patch

as an example of how to do it

it's only to demonstrate how it is done which is not like a bezier patch with quad cubic / 16 points

so if anybody knows a script like this i would appreciate if you could share the link/ script

Note: i know from a practical point of viw it's not veryr usefull anymore but it will show how it is done !*

Thanks

Answer 3

i check thsi site for openGL

but this is not python and relies mostly on opengl ccommands!

now there msut be a python sript for this bezier triangle patch !

hope someone can provide a link

Thanks & happy blendering
