Appl. No.:

10/913637

Inventors:

Christopher J. Goodman - Round Rock TX, US

International Classification:

G06T 15/40

US Classification:

345421

Abstract:

Graphics processing devices and methods are provided for culling small primitives that do not cover any pixels. A boundary (e. g. , a diamond) is defined around a pixel center, with pixel coverage being determined for some types of primitives based on whether the boundary is crossed. The boundaries divide the raster into internal regions and external regions. Each region is assigned a unique canonical identifier. Each vertex of a primitive is assigned the canonical identifier corresponding to the region that contains that vertex. The canonical coordinates of the vertices are used to cull primitives that do not satisfy the boundary crossing coverage rules for any pixels.

International Classification:

G02B 27/01

G06F 3/01
G06F 3/04815

Abstract:

In one embodiment, a method includes, by one or more computing devices, determining, based on first tracking data, a first viewpoint of the user and a first hand pose of the user. The method may include generating a virtual object in a virtual environment based on the first hand pose and a predetermined spatial relationship between the virtual object and the hand of the user. The method may include rendering a first image of the virtual object as viewed from the first viewpoint. The method may include determining, based on second tracking data, a second viewpoint of the user and a second hand pose. The method may include adjusting the first image of the virtual object based on changes from the first hand pose to the second hand pose. The method may include rendering and displaying a second image from the adjusted first image viewed from the second viewpoint.

Abstract:

A system and method for binding instructions to a graphical processing unit (GPU) includes a GPU configured to receive bindlessly compiled instructions and interpret the bindlessly compiled instruction at runtime to identify a needed conversion The GPU generates a conversion information based on the bindlessly compiled instruction and needed conversion and converts the bindlessly compiled instruction according to the conversion information to generate a bound format instruction. The GPU may then execute the bound format instruction.
