Abstract: When generating a render output in which primitives to be rendered are to be clipped against a user-defined clip plane defined for the render output, and a primitive to be rendered is intersected by a user-defined clip plane defined for the render output, an edge representing the intersection of the primitive with the user-defined clip plane is determined. The rasteriser, when rasterising the primitive, then tests one or more regions of the render output being generated against the determined edge representing the intersection of the primitive with the user-defined clip plane to determine whether the region or regions should not be rendered for the primitive on the basis of the user-defined clip plane.

If any of (i), (ii) and (iii) is positive, the pixel is drawn as part of the line.

Abstract: One embodiment of the present invention sets forth a technique for rendering clipped paths by first generating clip stencil buffer state indicating pixels that are inside of the clip path. The clip stencil buffer state may also store an opacity value for each covered pixel to generate a mask that modulates the opacity of a draw path that is clipped. Clipped draw stencil buffer state is then generated indicating pixels of the draw path that should be covered based on the clip stencil buffer state and coverage of the draw path. The clipped draw path is then filled or stroked to produce the clipped draw path. The clip and draw paths may be filled or stroked without tessellating the paths. Path rendering may be accelerated when a GPU or other processor that is configured to perform operations to generate the clip stencil buffer state and the clipped draw stencil buffer state, and to fill or stroke the clipped draw path.

Abstract: Adaptive sampling alleviates aliasing by partitioning the field of view of an image sample point into depth regions. Portions of the scene are sampled within a depth region using sample rays. If a sample ray is not completely occluded in the depth region, corresponding sample rays are evaluated in adjacent depth regions. Sample rays can be recursively evaluated in further depth regions until all the subsamples intersect opaque objects or a depth limit or transparency threshold is reached. The value of an image sample point is the weighted combination of sample rays. The number of sample rays in each depth region may increase monotonically with distance along a line of sight from an image sample point for effects such as reflection, refraction, and illumination. The number of sample rays in each depth region may increase monotonically with distance from a focal plane for effects such as depth of field.
