Abstract:
1. A method for vertex processing in a graphics processing unit, the method comprising: receiving a planar reference grid of a plurality of intersecting lines with line intersections corresponding to grid points, at least one grid point being on an interior of the planar reference grid and other grid points being at exterior corners of the planar reference grid, the received planar reference grid being invariant between different cut planes and separate from a layout of data to be rendered; deforming the planar reference grid to fit a polygon representing a two-dimensional intersection of a first cut plane of the different cut planes with a three-dimensional geometry, the deforming comprising mapping the exterior corners of the planar reference grid to vertices of the polygon and computing coordinates of the grid points on the interior as a function of the mapping, the deforming being performed by a vertex processor of the graphics processing unit; repeating the deforming for each of the different cut planes with the three-dimensional geometry, the repetition providing a plurality of deformed planar reference grids; and rendering an image as a function of the deformed planar reference grids.
