Hi,
I don't know if you also want to fill the polgons or if you only want
wireframe?
If you want to fill them then the trick I use might be useful to you.
I create 2 Shape 3D's with different appearences.
1 is set for filled polygons and CULL_BACK
1 is set for polygon edges, and CULL_FRONT
Then I create a single geometry, and add it to both Shape3D's.
This has the effect ofdrawing only the visible edges of the geometry.
You can play with the polygon offset, and possibly put them in an
ordered group to perfect it if you have problems.
