Abstract:
1. A method for maintaining the quality of images generated by a graphics system, wherein the graphics system is configured to render samples into an available space of a frame buffer based on a programmable sample density, to filter the samples from the sample buffer into a double-buffered display area of the frame buffer, the method comprising: (a) computing a realizable sample density corresponding to a first number of passes of the graphics system for an animation frame in response to receiving input defining a new window size; (b) performing said computing one or more times to determine a value for the first number which corresponds to a realizable sample density which is greater than or equal to a user specified sample density; (c) writing to one or more programmable registers in the graphics system to set the first number of passes of the graphics system equal to said value.
