1. A method for rendering a geometry object in a computer-generated scene, the method comprising: dividing a screen space associated with a display screen into a plurality of regions; for each region: computing a first sampling factor in a horizontal dimension that represents a horizontal sampling factor for pixels located in the region, computing a second sampling factor in a vertical dimension that represents a vertical sampling factor for the pixels located in the region, computing a first offset in the horizontal dimension that represents a horizontal position associated with the region, and computing a second offset in the vertical dimension that represent a vertical position associated with the region; determining that the geometry object intersects more than one region; generating a first instance of the geometry object for a first region that the geometry object intersects; and generating a second instance of the geometry object for a second region that the geometry object intersects.
