Abstract:
1. In a graphics processing system, a method for determining values for pixels of an image of an environment represented by geometric primitives in a screen coordinate space, comprising: in a circuit of the graphics processing system, shifting the position of a geometric primitive of the geometric primitives in the screen coordinate space from a first pixel position to positions corresponding to respective sampling locations of a sampling pattern, the sampling locations being a respective sub-pixel offset from the first pixel position; rendering in the circuit the shifted geometric primitive positioned at each of the sampling locations to generate sample values for a respective set of pixels representing the shifted geometric primitive positioned at the each of the plurality of sampling locations; and calculating in the circuit values for a resultant set of pixels representing the rendered geometric primitive positioned at the first pixel position with the sample values for the respective sets of pixels generated for the geometric primitive positioned at the plurality of sampling locations of the sampling pattern.
