| 7990380 | Diffuse photon map decomposition for parallelization of global illumination algorithm A given computer graphics scene may be rendered as a set of triangles. A set of photons may be distributed over the scene, and a number of steps may be performed for each triangle. For each triangle, a list of photons may be constructed. For that triangle, a set of ... | 08/02/2011 |
| 7969437 | Method and apparatus for triangle representation Embodiments of the invention provide for accelerated polygon intersection testing of rays against a set of polygons. The amount of computation required in the rendering process is reduced by preprocessing the scene into a data structure that can be more efficiently ... | 06/28/2011 |
| 7952574 | Apparatus and method for a frustum culling algorithm suitable for hardware implementation A method and apparatus for a frustum culling algorithm suitable for hardware implementation. In one embodiment, the method includes the separation of coordinates of a normal vector of each frustum plane of a frustum view into positive normal coordinates and negative... | 05/31/2011 |
| 7786991 | Applications of interval arithmetic for reduction of number of computations in ray tracing problems Embodiments provide for ray tracing traversal that relies on selected geometrical properties of the application to reduce the number of operations required during each traversal step. The traversal algorithm does not depend on the number of rays in the group. As a r... | 08/31/2010 |
| 7755628 | Method and apparatus for multi-level ray tracing A method, apparatus, and system related to thermal management. The method includes generating a beam including a group of rays; evaluating the beam against a spatially ordered geometrical database until the beam can no longer be evaluated as a whole in order to disc... | 07/13/2010 |
| 7414624 | Apparatus and method for a frustum culling algorithm suitable for hardware implementation A method and apparatus for a frustum culling algorithm suitable for hardware implementation. In one embodiment, the method includes the separation of coordinates of a normal vector of each frustum plane of a frustum view into positive normal coordinates and negative... | 08/19/2008 |
| 7348975 | Applications of interval arithmetic for reduction of number of computations in ray tracing problems Embodiments provide for ray tracing traversal that relies on selected geometrical properties of the application to reduce the number of operations required during each traversal step. The traversal algorithm does not depend on the number of rays in the group. As a r... | 03/25/2008 |
