Wireframe rendering question for NURBS model
on Dec 28, 2009 at 10:38:39 pm

Hello.

I have an engineering model of a device which was created in Pro-E. It was exported as a STEP and imported into Maya 2009. The model is very detailed, and we plan to use that detail in our animation. We will be animating a "build" of the device, with parts floating together and assembling in space.

We do not have time to shade the device realistically, so we will be using a wireframe look. I found a great set of tutorials here:

http://ashutoshjha.org/tutorial/wireframe-render-in-maya.html

The contour Rendering option looks nice, but it renders too many facets (every little poly), or it renders way too little of the model, depending on the options I choose. I cannot get it to render a nice, clean wireframe.

I'm sure it's because of the parametric nature of the model. Maya tessellates it and the result is a jumble of lines. I can try to adjust the tessellation attributes, but I don't think I can ever tune them to a point where they don't generate an abundance of lines.

Any ideas here?

Thank you.

Duplicate all isoparms as curves ([Surfaces] Edit Curves->Duplicate Surface Curves) and attach a pfx brush ([Rendering] Paint Effects->Curve Utilities->Attach Brush to Curves). Render with the Maya SW renderer.
