I read the corresponding chapter of PBRT-v3, as well as Veach's thesis which introduced BDPT. However I didn't quite understand why we use the measurement equation. It seems that the measurement equation can be further formulated to obtain different light transport algorithms, such as photon map ...
I am trying to speed up efficiency of rendering multiple cubemaps representing irradiance of the scene. Instead of drawing one side of cubemap at a time, I tried to do some instanced draw to decrease overhead - multiple istances of each side at a time using combination of modern and standard Open...
My question is about spherical harmonic lightning, in the context of computing the coefficients with an expensive GI algorithm and passing them to the vertex shader
Another way is to just use an expensive GI algorithm to compute vertex colors and just use them instead.
What is the advantage of ...
Metal Best Practices Guide states that
The setVertexBytes:length:atIndex: method is the best option for binding a very small amount (less than 4 KB) of dynamic buffer data to a vertex function
I believe this means that instead storing uniforms in an overly complicated manually memory manag...
I recently implemented Mitchell-Netravali filtering in my path-tracer with 16x (4x4) temporal anti-aliasing. PBR's demonstration image shows it should give significantly better results than the box filter, but my test pictures barely show any improvement at all (and the sharpening in Mitchell-Net...
