Our reader ‘ihatedisqus3’ has also informed us about a new path tracer engine called Arauna2. Arauna2 is the successor to the CPU-based Arauna real-time ray tracer. It uses GPU path tracing to render scenes with global illumination and depth of field, at a speed that enables real-time previewing: during camera movement, images are noisy, but as soon as the camera stands still, the final image starts to converge.
Arauna2 uses CUDA for high-speed GPU-based path tracing, and uni-directional path tracing with extensive MIS and RIS for fast convergence, combined with the ‘wavefront path tracing’ algrorithm originally introduced by Dietger van Antwerpen.
As Jacco Bikker noted, the noise is due to the random process which is the basis of path tracing. In other words, it will take a while until we get noise-less scenes from all available path tracer engines. Keep also in mind that Jacco used two Titans in SLI for the following footages. Imagine now what it would take for scenes with less noise.
The following videos show off a Unity’s Robot Lab and a chunk of Minecraft scenery.
A demo of Arauna2 is now available here, though we suggest paying also a visit to its official forum.
Enjoy!

While he is a die-hard PC gamer, his gaming roots can be found on consoles. John loved – and still does – the 16-bit consoles, and considers SNES to be one of the best consoles. Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2. John has also written a higher degree thesis on the “The Evolution of PC graphics cards.”
