1. A method comprising: computing data that defines a rectangular area of pixels that bounds a triangular area of the pixels; selecting a line of pixels within the rectangular area of pixels; sequentially evaluating coordinates associated with the pixels of the line of pixels to determine whether the pixels fall within the triangle area; ceasing evaluation of the coordinates associated with the pixels of the line of pixels upon determining that at least one pixel of the line falls within the triangle area and a current pixel no longer falls within the triangle area; and updating pixel data for the pixels that fall within the triangle area to render the triangular area.
