Abstract
In one embodiment, a method for computing a color value for a sampling pixel region includes using a computing system to determine a sampling pixel region within a texture. The texture is associated with mipmap levels having different resolutions of the texture. The mipmap levels include at least a first mipmap level defined by color texels and a second mipmap level defined by distance-field texels. The system may select one of the mipmap levels based on a size of the sampling pixel region and a size of a texel in the selected mipmap level. The system may then compute a color value for the sampling pixel region using the selected mipmap level.
