RAY-BOX INTERSECTION TESTING USING DOT PRODUCT-BASED FIXED FUNCTION LOGIC |
| 摘要 |
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. |
