Abstract
Official abstract text for this publication.
A method and apparatus for ray tracing may include using texture pipeline hardware of a GPU to perform ray intersection testing for a first ray and a first shape. Using the texture pipeline hardware to perform ray intersection testing may include calculating a plurality of dot products with the texture pipeline hardware, and determining whether the first ray intersects the first shape based on the plurality of dot products.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for ray tracing, comprising: using texture pipeline hardware of a graphics processing unit to perform ray intersection testing for a first ray and a first shape, including: calculating a plurality of dot products with the texture pipeline hardware; and determining whether the first ray intersects the first shape based on the plurality of dot products. 2 . The method of claim 1 , wherein the first shape is one of a bo…
