Publication number: 20240104844Abstract: Devices and methods for multi-resolution geometric representation for ray tracing are described which include casting a ray in a space comprising objects represented by geometric shapes and approximating a volume of the geometric shapes using an accelerated hierarchy structure. The accelerated hierarchy structure comprises first nodes each representing a volume of one of the geometric shapes in the space and second nodes each representing an approximate volume of a group of the geometric shapes. When the ray is determined to intersect a bounding box of a second node representing one group of the geometric shapes, a selection is made between traversal and non-traversal of other second nodes based on a LOD for representing the volume of the one group of geometric shapes.Type: ApplicationFiled: September 28, 2022Publication date: March 28, 2024Applicants: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Sho Ikeda, Paritosh Vijay Kulkarni, Takahiro Harada
