  • Point-based guided importance sampling
    Patent number: 8866813
    Abstract: A computer-animated scene illuminated by indirect light is shaded. The scene is comprised of sample locations on a surface element of an object in the scene. A point cloud representation of the scene is generated. Optionally, an importance map of the scene, based on the point cloud representation, is generated. The importance map is generated by rasterizing one or more points in the point cloud and designating areas of interest based on the energy value of the one or more points in the point cloud. A ray tracing engine is biased, based on the importance map. The biased ray tracing engine calculates the path of the ray to the sample locations in the scene to an area of interest. The scene is shaded using the output from the biased ray tracing engine.
