Help: About the filling of 3D graphics

anabble

Existing three-dimensional graphics, such as DXF and 3DS files, need to fill in points on each surface at a certain interval. The surface is generally a triangle. Now the method used is to find the middle point for the three points of the triangle and use a recursive algorithm to The entire graph is filled. But this method requires enough memory (because of the small spacing between graphics) and is slower. So here I ask you prawns. I wonder if there is a better way? ? ? ? ?

It's better to paste texture on the surface.

I need all point data.
The main problem is to layer three-dimensional graphics. Divide data by layer.
