What is Light Tracing? What is Instant Radiosity?
Light Tracing
Reverse Monte Carlo Path Tracing. Start pathes in random light sources. In the absorption case, connect from the current point to the viewer. Advantage: Can detect high energy pathes.
Instant Radiosity
Efficient diffuse illumination utilizing Light Tracing and hardware rasterization.
Shoot photons from light sources. At every bounce, place a point light source at the photon position and render the scene with diffuse lighting and shadow mapping. Accumulate the brightness values of all pixels in a buffer (weighted by current photon energy).
Corresponds to bi-directional evaluation of pathes:
