Wireframe displaying also back faces

#1

Hello,

There are a lot of techniques to render the wireframe of an object, but each one only displays the front faces of the object (usually over an ambiant occlusion or the final render of the mesh). Is there a way to display the full wireframe, with the contour of the back faces, as seen in Maya’s viewport ?

The only way I can see is creating a UV map and connecting it to the transparency, but that would require editing the line thickness in Photoshop. There must be a way to do everything in Maya but I can’t see it…

Thanks in advance.

You can use the hardware render buffer, which can do multiple passes with anti aliasing. But there’s this issue

Maybe Normalize the face UVs and connect a box ramp to cutout/transparency.

These days I use VP2.0 more and more, depends on your needs tho’.

Normalize and ramp on transparency is a good idea, but depending on the mesh, normalizing each face can be quite tedious. Some faces are not square but parallelepiped and Normalize doesn’t correct that, even with “keep ratio” unchecked. Works well on cubes though.

As for hardware render, I am not much familiar with it, but I’ll try to look a bit inside when I have the time.
