Abstract
Disclosed are apparatuses, systems, and techniques to render images with global illumination using efficient ray tracing, light source identification, and reservoir resampling that deploys temporal and spatial reservoirs.
Claims20
A method comprising:
- identifying, for a pixel of an image of a scene, a point in the scene as contributing to illumination of the pixel;
- updating, based at least on the point, radiance information for the pixel, wherein the radiance information is based at least on one or more previously identified points in the scene as contributing to illumination of at least one of a plurality of pixels in at least one of:
- the image of the scene, or
- one or more previous images of the scene,
- wherein the plurality of pixels is associated with at least one of:
- the pixel, or
- a predetermined pixel neighborhood of the pixel;
- and
- rendering, using the updated radiance information, the image of the scene.

A system comprising:
- a memory device;
- and
- one or more processing units, communicatively coupled to the memory device, to:
- identify, for a pixel of an image of a scene, a point in the scene as contributing to illumination of the pixel;
- update, based at least on the point, radiance information for the pixel, wherein the radiance information is based at least on one or more previously identified points in the scene as contributing to illumination of at least one of a plurality of pixels in at least one of:
- the image of the scene, or
- one or more previous images of the scene,
- wherein the plurality of pixels is associated with at least one of:
- the pixel, or
- a predetermined pixel neighborhood of the pixel;
- and
- render, using the updated radiance information, the image of the scene.
9 more elements
A processor comprising one or more processing devices, to:
- identify, for a pixel of an image of a scene, a point in the scene as contributing to illumination of the pixel;
- update, based at least on the point, radiance information for the pixel, wherein the radiance information is based at least on one or more previously identified points in the scene as contributing to illumination of at least one of a plurality of pixels in at least one of:
- the image of the scene, or
- one or more previous images of the scene,
- wherein the plurality of pixels is associated with at least one of:
- the pixel, or
- a predetermined pixel neighborhood of the pixel;
- and
- rendering, using the updated radiance information, the image of the scene.
