Abstract: Methods and apparatus for radial gradient rendering are provided. A graphics computing device can include a radial gradient module (RGM), which can include circuitry for radial gradient rendering. The RGM can receive one or more parameters associated with rendering at least a portion of an image utilizing radial gradient rendering. The RGM can map one or more input coordinates of the image to one or more source domain coordinates. The RGM can determine a t-value for the source domain coordinates, the t-value specifying an ellipse in the source domain whose edge includes the source domain coordinates. The RGM can determine a color value for the input coordinates based on the specified ellipse. The RGM can generate an output that is based on the color value.
