Yafray hack: Accelerated Photon Map Rendering

Bart · January 25, 2006

RCRuiz has posted a hack that speeds up Photon Map rendering in Yafray a great deal. It’s a bit thin on the details but it would seem that he stores the photon distribution in your scene so that you can quickly re-render it from any camera angle and position.

As long as you don’t move any objects or lights this should work fine. For many types of fly-through animation, such as architectural walkthroughs, this will be a great timesaver.

The downloads and instructions can be found on Elysiun.

Hi B@rt, RCRuiz is also working on a PovRay exporter that uses the same technics of this yafray’s hack, it can store the radiosity and photon data to be used on a walktrhow animation.

Hi davidOmatic, In the blenpov I simple use the radiosity and phothon recording that is include on standar Pov. I did not have to hack the code to do it ;)
