Claim 16:
17. The rendering system of claim 12 further configured such that, if a particular fragment fails a depth test performed using a depth value stored in the second depth buffer, the depth testing logic is configured to:
perform a second depth test on the particular fragment using the appropriate depth value stored in the first depth buffer;
wherein the rendering system is configured to, if the particular fragment passes the second depth test: (i) resolve the fragments of the second depth buffer, (ii) use the depth values of the resolved fragments to update the depth values in the first depth buffer, and (iii) perform a third depth test on the particular fragment using the appropriate depth value stored in the first depth buffer after the updating of the depth values in the first depth buffer; and
wherein the rendering system is configured to discard the particular fragment if the particular fragment fails the second depth test.
