Abstract
During the rendering of an image, specific pixels in the image are identified where antialiasing would be helpful. Antialiasing is then performed on these identified pixels, where antialiasing is a technique used to add greater realism to a digital image by smoothing jagged edges. This reduces a cost of performing antialiasing by reducing a number of pixels within an image on which antialiasing is performed.
Claims20
A method comprising:
- identifying complex pixels within a scene to be rendered;
- and
- performing antialiasing on each of the complex pixels within the scene, utilizing ray tracing.
A system comprising:
- a processor that is configured to:
- identify complex pixels within a scene to be rendered;
- and
- perform antialiasing on each of the complex pixels within the scene, utilizing ray tracing.

A method comprising:
- rendering a non-antialiasing G-buffer for a scene;
- identifying visible pixels within the scene that are partially covered by one or more instances of geometry;
- and
- tracing rays through the identified pixels to generate samples for the G-buffer.
