Patents by Inventor Rowan Wyborn

Rowan Wyborn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9928641
    Abstract: Systems and methods are provided for simulating shadows in a scene. In an embodiment, two or more light sources that cast shadows from objects are identified. Each of those light sources is then assigned to a channel in a shadow mask buffer. The shadows are then accumulated into the shadow mask buffer and may be combined with corresponding lights to render the scene.
    Type: Grant

  • Patent number: 8368693
    Abstract: Example embodiments of the present invention include systems and methods for the efficient rendering of multiple light sources, each controlled individually, in a single pass. An example embodiment encodes the light sources in a texture map, such as DXT. Each channel of the multi-channel texture map encodes data associated with a light source. The pixel shader then renders multiple light sources according to the multiple channels of the texture. Additionally, the pixel shader may render multiple textures, and thus render an even greater number of individual light sources. In a further embodiment, the rendering of a plurality of individually controlled light sources is accomplished in a single pass.
