Patent ID: 8854374

Claim:
A computer-implemented method for generating primitives in a grid, comprising: generating, by a computing device, a set of vertices in a section of the grid, wherein the grid comprises multiple levels arranged adjacently along a boundary edge of the grid; generating, by the computing device, a rendering order for the set of vertices based on a proximity of each vertex of the set of vertices to the boundary edge of grid and a proximity of each vertex of the set of vertices to an outside level of the multiple levels; selecting, by the computing device, a first vertex in the set of vertices based on the rendering order; generating, by the computing device, multiple primitives utilizing a sectional pattern, the sectional pattern based on (i) generating, in each level of the multiple levels, primitives that share the selected first vertex, prior to selecting another vertex for additional primitive generation, and (ii) generating the primitives across the adjacent multiple levels of the grid along the boundary edge of the grid and in an order corresponding to the rendering order.
