摘要： A method and apparatus for binary classification includes using signs of float values to detect different subgroups, detecting whether all entries in the group belong to the same subgroup, splitting original subgroup into uniform subgroups and classifying subgroups using array of float values. Coherency in groups of rays is detected by generating a group of rays, determining an originating point and a direction for each ray in the group, determining coherency of the group of rays and determining a group of rays as coherent as one in which all rays determined to travel in the same direction for each coordinate x, y, and z and determining a group of rays as incoherent otherwise and traversing the group of incoherent rays differently from the coherent group of rays.

摘要： 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 traversed. During the preprocessing stage, triangles such as triangle may be converted into vertex and edge representation.

摘要： 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 result, multi-level traversal schemes may be implemented, starting with a large number of rays in a group and then reducing it as needed to maintain group coherency. Multi-level traversal schemes may be created by splitting large groups of rays while traversing acceleration structures.

摘要： A block decomposition based method is provided for compressing textures based on sharing color information between texture blocks. The texture map is divided into a plurality of texture blocks containing texels. During compression a first color value is stored for a first block and a second color value is stored for a second block. A palette is created for each texture block using the color values stored for several neighboring texture blocks. Each texel in each of the texture blocks is indexed to one of the colors in the palette. Accordingly the method compresses the information in the texture map by storing for each texture block bits representing a color value and bits to index each of the texels to a color in the palette, which allows sharing of color information between blocks. During decompression the palettes are regenerated and colors from the palette are assigned to the texels according to the stored index values. Accordingly, the decompression of the texture allows regeneration of the compressed texture, which may be mapped to surfaces to improve the visual quality of three-dimensional graphics.

摘要： 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 normal coordinates. In one embodiment, the separation of the coordinates of each normal vector of the frustum planes enables implicit selection of the coordinates of a negative vertex (N-vertex) of an axis-aligned bounded box (AABB). Once implicitly selected, it is determined whether the N-vertex of the AABB is outside at least one frustum plane. In one embodiment, a determination that the N-vertex of the AABB is outside at least one of the frustum planes provides a trivial reject of objects enclosed by the AABB that are therefore is excluded from the rendering process. Other embodiments are described and claimed.
