Point-Based Guided Importance Sampling

View page
US Patent:
20130002671, Jan 3, 2013
Filed:
Jun 30, 2011
Appl. No.:
13/174385
Inventors:
Chris F. ARMSDEN - Burbank CA, US
Bruce Tartaglia - Santa Monica CA, US
Assignee:
DreamWorks Animation LLC - Glendale CA
International Classification:
G06T 15/60
US Classification:
345426
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.

US Patent:
20140267357, Sep 18, 2014
Filed:
Mar 15, 2013
Appl. No.:
13/844436
Inventors:
DreamWorks Animation LLC - , US
Chris F. Armsden - Burbank CA, US
Assignee:
DreamWorks Animation LLC - Glendale CA
International Classification:
G06T 11/40
US Classification:
345589
Abstract:
A computer-enabled method for shading locations for use in rendering a computer-generated scene having one or more objects represented by a point cloud. The method involves selecting a shading location, selecting a set of points from the point cloud, rasterizing the points onto a raster shape positioned at the shading location, where the raster shape has varying texel densities that are based on characteristics of the points in the point cloud, such that the texel density varies on different surfaces of the raster shape or on different areas of the same surface or both, and shading the shading location.
