Re: Photon Beam Diffusion: A Hybrid Monte Carlo Method for S

I've recently implemented this, with good results (particularly from the diffuse multiple scattering) but I'm stuck on how to numerically integrate the diffusion in order to calculate the Rd->alpha_prime table for artist-friendly parameterization. Has anyone else implemented this? Or has read the pa...

Re: Phong fireflies

My suggestion is to clamp the sample contribution in image space to some maximum value. Implementation is trivial and doesn't require any path and material roughness tracking. The downside of this method, however, is that you will end up clamping contributions that are not noisy, e.g. directly visi...
