plot triangular Bezier surface

how I can plot a triangular Bezier surface on a triangular domain ? using mesh or other command

thank you very much

Dear friends, I have a new graphic which you create with the help of the book called curves and surfaces in geometric modeling, there it details the algorithm to generate a triangular surface. I generated this image but I did it in python.

Hi , can i get the code of that triangular patch in python or matlab , and thanks

I haven’t done that myself, but you might consider the trimesh function.

thank you very much, I'll try

[Star Strider]

My pleasure!

After a few days, to achieve it,using trimesh and MESH2D - Automatic Mesh Generation

Congratulations!

If you can generalise your algorithm to a function, consider uploading it to the File Exchange. There could be a need for it. (When I searched there, I didn’t find anything that seemed to do what you want, my reason for suggesting trimesh.)

I didn’t know MESH 2D existed. It looks useful, so I bookmarked it. Thanks!

junior! Would you please explain how did you get the triangular domain?

 I need the toolbox MESH2D - Automatic Mesh Generation.
If you can give me some ideas,I will very thank you.
