Abstract: Rendering system combines point sampling and volume sampling operations to produce rendering outputs. For example, to determine color information for a surface location in a 3-D scene, one or more point sampling operations are conducted in a volume around the surface location, and one or more sampling operations of volumetric light transport data are performed farther from the surface location. A transition zone between point sampling and volume sampling can be provided, in which both point and volume sampling operations are conducted. Data obtained from point and volume sampling operations can be blended in determining color information for the surface location. For example, point samples are obtained by tracing a ray for each point sample, to identify an intersection between another surface and the ray, to be shaded, and volume samples are obtained from a nested 3-D grids of volume elements expressing light transport data at different levels of granularity.

Abstract: Disclosed is a graphics system and associated methodologies for selectively increasing the level-of-detail at specific parts of a mesh model based on a point cloud that provides a higher detailed representation of the same or similar three-dimensional (“3D”) object. The graphics system receives the mesh model and the point cloud of the 3D object. The graphics system determines a region-of-interest of the 3D object based in part on differences amongst points that represent part or all of the region-of-interest. The graphics system reconstructs the region-of-interest in the mesh model and generates a modified mesh model by modifying a first set of meshes representing the region-of-interest in the mesh model to a second set of meshes based on the positional elements of the point cloud points. The second set of meshes has more meshes and represents the region-of-interest at a higher level-of-detail than the first set of meshes.

An intersection detected with the implicit geometry may be found concurrently with intersections for the same ray with explicitly-defined geometry, and data describing these intersections may be stored with the ray and resolved.
