Abstract
A graphical processing unit (GPU) and methods for rendering a three-dimensional (3D) scene generated in a field of view having in-focus and out-of-focus regions on a two-dimensional (2D) screen region of pixels are described. One method includes initially rendering the scene to create color and depth texture maps and creating mip-map layers for the color texture map. The method further comprises subsequently rendering the scene by, for each pixel: creating a mip-map layer selection value as a function of a depth of the pixel from the depth texture map, generating a color value by interpolation using color values from at least one of the mip-map layers chosen according to the mip-map layer selection value, and setting a color of the pixel to the generated color texture.
