Test 003: K3D + 3Delight

Same as Test‑001, using 3Delight renderer instead of Pixie (was Aqsis with Test‑002). 3Delight shown to be 6 times faster than Pixie and 24 times faster than Aqsis. It also produced less artifact with the same eye‑splits value, as you can see when the ground traverse the camera center. Future tests will all be done with 3Delight, as it seems to be the best of all three.
