Fast 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 کاملLocalizing the Final Gathering for Dynamic Scenes using the Photon Map
Rendering of high quality animations with global illumination effects is very costly using traditional techniques designed for static scenes. In this paper we present an extension of the photon mapping algorithm to handle dynamic environments. First, for each animation segment the static irradiance cache is computed only once for the scene with all dynamic objects removed. Then, for each frame,...
متن کاملRobust Diffuse Final Gathering on the GPU
This paper presents a method to obtain the approximate indirect diffuse reflection on a dynamic object, caused by a diffuse or a moderately glossy environment. Instead of tracing rays to find the incoming illumination, we look up the indirect illumination from a cube map rendered from the reference point that is in the vicinity of the object. However, to cope with the difference between the inc...
متن کاملPhoton Map Gathering on the GPU
Photon mapping methods obtain the indirect illumination of a point by finding those photon hits that arrived at the neighborhood of the point on the object surface. This paper proposes a method that stores the photon hits in a texture of the graphics hardware and replaces the traditional kd-tree based neighborhood searches by the filtering of this texture. This step finds the irradiance of all ...
متن کاملExclusive Final States from Photon - Photon Collisions at Spear
Studies of exclusive final states produced by the two-photon process have been made at SPEAR by the Mark II and by the Crystal Ball Collaborations. region 500 MeV/c2 Measurements of r%rand x0x0 production in the mass < mx, < 2000 MeV/c2 are presented. These data include strong signals from the well-known f(1270) meson. The A2(1310) has been observed via its rr"n decay mode and its partial width...
