A graphics system and method for rendering image on a display device. The graphics system receives 3D graphics data including vertices for a triangle. The triangle is tested to determine if it is larger than a maximum triangle size, and if so, it is fragmented into sub-triangles smaller than the maximum size. After this size limiting, a bin bounding box is computed for each triangle. The absolute coordinate of a triangle's vertices are converted into relative coordinates with respect to an origin (e.g. a corner) of the bin box. Succeeding rendering computations (e.g. computations to determine whether sample positions fall interior to the triangle or to interpolate ordinate values for the interior samples) are performed using the relative coordinates. The positions of samples are also represented in relative coordinates (with respect to the bin box origin).
