Jacopo Pantaleoni then stationed at Weta's New Zealand headquarters for a few months, helping them develop a
pre-computed ray tracing engine to process billions of triangles in Avatar. They named it "
PantaRay", derived from the Greek motto "panta rhei" (all things flow). Explained from a non-professional language, this engine greatly accelerates the CG production and rendering process, allowing Weta to use less time to create more complex scenes. For example, there is a scene in the movie where a large group of purple aliens are seen leaping from the helicopter. The background is forest-covered mountains. Using PantaRay, it took only a day and a half to complete the pre-calculation, and the previous rendering method It will take up to a week.
NVIDIA also claims that the PantaRay ray tracing rendering processor can perform up to 25 times faster on the Tesla S1070 GPU computing server than on a normal CPU server
