Abstract
In one embodiment, a method includes projecting a triangle primitive of an object defined in three-dimensional space onto a two-dimensional space, accessing a distortion map generated based on distortion characteristics of a display system, distorting a grid representation of a screen of the display system using the distortion map, determining a visibility of the triangle primitive relative to pixels of the screen by comparing the projected triangle primitive and the distorted grid representation of the screen, rendering an image based on the determined visibility of the triangle primitive, the rendered image being configured to be displayed by the screen of the display system having the distortion characteristics.
