Here's a technique that I've been thinking about, but have never seen implemented. I'd like to do the technique mentioned here
(http://www.drone.org/tutorials/rayDisplace_userGallery.html)
using displaced simple geometry, but instead of character animation I'd like to try architectural interior illumination.
If I can use a simplified mesh to calculate a GI/photon mapping solution for bounced illumination, and then displace the geometry for the final render, this could be a really powerful way to speed up the GI calculations for interior lighting, while retaining the level of detail necessary to achieve realism for virtual sets.
Has anyone tried this? It seems possible but I've never seen it mentioned. Only a couple of the current crop of raytracers (Mental Ray and PRMan 11) have micropoly displacement so perhaps people haven't tried it yet. Brazil 2.0 should have it which may help. I'm still learning Renderman/Pixie so I'll try it as soon as I feel more confident with my skills.
