Abstract: Disclosed is a cloud network server system, a method and a software program product for experiencing a three-dimensional (3D) model. 3D model data associated with a 3D video game is uploaded to the cloud network server system. These are used to design for example a computer game that renders non-spatial characteristics such as, smell, reflection and/or refraction of light, wind direction, sound reflection, etc., along with spatial and visibility information associated with 3D objects displayed in the 3D video game. Different versions of the 3D model are created based on memory, streaming bandwidth, and/or processing power requirements of different user terminal computers. Based on a virtual location of a user in the 3D model, parts of at least one version of the 3D model are rendered to the user. This renders a more lifelike virtual reality gaming experience with substantially lesser time lag and lesser memory footprint requirement.

Abstract: Techniques are disclosed for simplifying an occluder representing 3D graphics data. Graphics data corresponding to one or more 3D objects is voxelized. A plurality of planes is generated to intersect the voxelized graphics data. Intersections between the planes and the voxelized graphics data are evaluated to identify corresponding slice polygons from the intersections. A subset of the planes is selected to maximize a correctness of a simplified occluder. The simplified occluder representing the object is generated from a union of the selected subset of the planes.
