Efficient Importance Sampling Techniques for the Photon Map
نویسندگان
چکیده
In global illumination computations the photon map is a powerful tool for approximating the irradiance, which is stored independent from scene geometry. By presenting a new algorithm, which uses novel importance sampling techniques, we improve the memory footprint of the photon map, simplify the caustic generation, and allow for a much faster sampling of direct illumination in complicated models as they arise in a production environment.

Importance Driven Path Tracing using the Photon Map
This paper presents a new importance sampling strategy for Monte Carlo ray tracing in which a rough estimate of the irradiance based on the photon map is combined with the local re ection model to construct more e cient probability density functions that can be used in an importance sampling scheme The algorithm gives unbiased results handles arbitrary re ection models and it is particularly e ...
متن کاملPixel Cache Light Tracing
In this paper, we introduce Pixel Cache Light Tracing, which is a new low-noise combination of eye-path and light-path tracing. In the first pass, eye-path vertices are distributed from the observer and stored in a hit point map analogous to progressive photon mapping. In the second pass, photons are traced from the light source and projected to the image as well as gathered by the hit point ma...
متن کاملCombined Correlated and Importance Sampling in Direct Light Source Computation and Environment Mapping
This paper presents a general variance reduction method that is a quasi-optimal combination of correlated and importance sampling. The weights of the combination are selected automatically in order to keep the merits of both importance and correlated sampling. The proposed sampling method is used for efficient direct light source computation of large area sources and for the calculation of the ...
متن کاملFast Final Gathering via Reverse Photon Mapping
We present a new algorithm for computing indirect illumination based on density estimation similarly to photon mapping. We accelerate the search for final gathering by reorganizing the computation in the reverse order. We use two trees that organize spatially not only the position of photons but also the position of final gather rays. The achieved speedup is algorithmic, the performance improve...
متن کاملPlane Sampling for Light Paths from the Environment Map
We present a method to start light paths on an emitting environment map in the context of Monte Carlo global illumination with image-based lighting or physical sky models. With this technique we can efficiently render unbiased caustics from these kinds of lights, for example using bi-directional path tracing. Additionally it is now possible to use algorithms like multiple importance sampling, p...
