Abstract:
We present a new Monte Carlo method for solving the global illumination
problem in environments with general geometry descriptions and
light emission and scattering properties. Current
Monte Carlo global illumination algorithms are based
on generic density estimation techniques that do not take into account any
knowledge about the nature of the data points --- light and potential
particle hit points --- from which a global illumination solution is to be
reconstructed. We propose a novel estimator, especially designed
for solving linear integral equations such as the rendering equation.
The resulting single-pass global illumination algorithm promises to
combine the flexibility and robustness of bi-directional
path tracing with the efficiency of algorithms such as photon mapping.
