Paint Effects is still one of the best tools in Maya. A friend of my colleague suggested this really nice method to visualize geometry intersections (intersection between objects and self-intersection as well).
I just put together a simple script for doing this a little bit easier: pfxIntersectionDetector
It’s not Houdini, but it can be really useful if you modeling objects for simulation in Maya.
How to use it:
- Select an object or objects
- Run the script
- There is a Line With and the a Self Intersection attribute on the generated pfxToon transform node for easier adjustments.
note: This could be very slow if you use it on high-resolution objects and you have a lot of intersection.
