Abstract

Methods, systems, and computer readable media embodiments are disclosed for generating primitives in a grid. Embodiments include generating a set of vertices in a section of the grid, selecting one or more vertices in the set of vertices in an order based on a proximity of the vertices to a boundary edge of the grid, and generating primitives based on the order of the selected vertices.
