When a ray passes through both sides of a splitting plane, the “far” sub-tree is pushed into the stack and the “near” sub-tree is traversed first.

Abstract: Position and orientation information of a specific part of an observer is acquired (S403). It is determined whether or not a region of a specific part virtual object that simulates the specific part and that of another virtual object overlap each other on an image of a virtual space after the specific part virtual object is laid out based on the position and orientation information on the virtual space on which one or more virtual objects are laid out (S405). When it is determined that the regions overlap each other, an image of the virtual space on which the other virtual object and the specific part virtual object are laid out is generated; when it is determined that the regions do not overlap each other, an image of the virtual space on which only the other virtual object is laid out is generated (S409).

Abstract: The range of depth values within the overlap of a convex polygon and a square or rectangular rasterization area can be determined by identifying whether the minimum and maximum depth values occur at the corners of the rasterization area or at intersections of the polygon's edges with the area's sides. By choosing between the corner and intersection for both the minimum and maximum depth limit, solving the depth plane equation at the chosen location, and clamping against the polygon's vertex depth range, a tight depth range describing the depth values within that overlap are obtained. That tight depth range is utilized to cull pixel values early in the pipeline, improving performance and power consumption.

According to the present invention, the assignment of mesh sections to the classes is adapted by using actual feature information from the unseen image. Advantageously, this allows for an adaptation of the feature category to which the mesh section is assigned and thereby allows an improved segmentation of the object.

Abstract: A graphics-processing unit is used to perform mesh simplification. A vertex shader receives a dataset for an input mesh that portrays a three-dimensional graphics object. The vertex shader generates from the dataset vertices for primitives that make up the input mesh. The input mesh is divided into a grid of cells. A geometry shader receives the vertices from the vertex shader and generates from the received vertices a simplified mesh that portrays the three-dimensional graphics object in less detail than the input mesh. Before the input mesh is divided into grid cells, a warping function can be applied to the input mesh based on a weighting function to warp the input mesh, thereby increasing sampling at a region of interest. A projective warping can be performed on the grid to produce grid cells of different volumes in accordance with a camera position.
