Fast depth of field simulation

摘要

A method, system, and computer-readable storage medium are disclosed for rendering a scene with a simulated depth of field blur. In one embodiment, the scene comprises a plurality of polygons, each polygon comprises a respective plurality of vertices, and each of the vertices has a respective depth. A respective blur radius may be determined for each vertex of each polygon as a function of the depth of the vertex. A respective blur radius may be determined for each pixel in each polygon based on the blur radii for the vertices of the polygon. Each pixel in each polygon may be rendered using the respective blur radius determined for the pixel.
