Is it possible to recreate wireframe texture in Mitsuba 3?

[jaroslavknotek]

The documentation from version 0.4.3 - section 8.6.3 shows a wireframe texture.

I was wondering if it is possible to render a model and reveal its mesh in the same manner in the current version of mitsuba3.

I tried applying mesh_attribute texture with random face_color the same way it's in the current documentation:

It reveals the structure but I don't think it's the same as a wireframe.

Hi @jaroslavknotek

This hasn't been ported to Mitsuba 3, and there currently isn't any plan to do it either.

That said, I do think that this might still be possible in a custom mi.Texture plugin. I don't know how the original implementation worked, but any call to Texture.eval() passes a SurfaceInteraction3f which should hold enough information to determine whethere or not the current point is close enough to an edge to be rendered with a different color (wireframe color).

Thank you, I will try that.
