摘要： Methods, systems and data structures produce a rasterizer. A graphical state is detected on a machine architecture. The graphical state is used for assembling a shell rasterizer. The machine architecture is used for selecting replacement logic that replaces portions of shell logic in the shell rasterizer. The machine architecture is used for selectively inserting memory management logic into portions of the shell logic to produce.

摘要： A virtual reality system surveys a real-world environment, generates 3D data that defines the real-world environment, renders a virtual 3D environment using the 3D data, retrieves a virtual object from a database comprised of pre-stored virtual objects, renders the virtual object in the virtual 3D environment, and re-positions the virtual object in the virtual 3D environment.

摘要： Portable virtual reality is disclosed. A digital camera captures an input video stream comprising video frames that carry information about a surrounding environment limited by a field of view of the camera. The input video stream is processed by a handheld computer coupled to the camera. Parameters that define a rendered scene of a virtual environment are adjusted based upon motion parameters extracted from the input video stream by the handheld computer during the processing.

摘要： Various methods, apparatuses, and systems are described in which subdivided polygons are derived from a first polygon. Bin assignments of subdivided polygons derived from a first polygon may be stored. One or more reference coordinate points associated with coordinates of the first polygon may be stored. One or more reference coordinate points associated with the coordinates of the first polygon on a subsequent frame may be compared to the stored one or more reference coordinate points from a previous frame. The bin assignments for the corresponding subdivided polygons for the subsequent frame may be reused if the results of the comparison are within a preset threshold quantity.

摘要： In rendering an image of a 3D surface, a computer system obtains a digital model that includes data points defining vertices for triangles that represent 2D faces of the 3D surface. The computer also obtains a plurality of vectors, each defining a surface normal for the 3D surface at a corresponding one of the vertices. The computer applies an algorithm, such as, Loop's Equation, to the data points to create new data points defining new vertices that subdivide the triangles into smaller triangles. The computer applies the same algorithm to the vectors to calculate new vectors, each defining a surface normal at a corresponding one of the new vertices.

摘要： Apparatus, systems and methods for optimized frustum clipping via cached clip vertices are disclosed. For example, a method is disclosed, the method including generating a clip vertex for a leading edge of a triangle of a triangle strip or fan, indicating that the leading edge is shared with an adjacent triangle of the triangle strip or fan, and in response to the indication, using the clip vertex as a clip vertex of a trailing edge of the adjacent triangle in the triangle strip or fan. Other implementations are disclosed.
