RenderAnts: Interactive Reyes Rendering on GPU

I've seen this at Blendernation.com...The name says it all, and it sounds really promising.

The interactivity may not seem as great as what real-time raytracers shown, but it's important to note that there is no progressive refinement going on. And the most important, if I understood well, as it renders directly rib shaders, most renderman features should be supported.

How do we get this?

The GPU stuff has a long ways to go, NVidia's Fermi architecture with 512 cores will bring real time RT GI a lot closer to the gaming world (or AI), hopefully replacing the limited rasterization techniques used today. Pushing a game through a render engine is no laughing matter either

.It's usage in 3D is limited for the moment, check out VRay RT for example. To be usable in animation any noise/artifacts would have to resolve entirely before you could call a frame complete. Those times, at the moments, don't differ a huge amount from regular rendering, but for product demonstrations, where perfection isn't as important as a final product, the future is looking bright for the visualization guys.

RenderAnts currently isn't using any Raytracing or adaptive algorithm its a true reyes rendering system so its just like 3Delight or Prman in that respect, just moving a lot of the functionality to the GPU, so its not about interactive but simply being faster as standard quality rendering. The scenes from Elephants Dream aren't realtime by any means, but still much faster. RenderAnts is all about making a production quality GPU based renderer that is fast, not about making a realtime renderer.

Fermi is at the moment nothing more than a paper architecture. If they can actually deliver any chips that actually will work at a reasonable price at a reasonable time with reasonable GRAPHICS performance, (please note GRAPHICS) is still written in the stars.

In the near future this has more practical use in faster previews during production, rather than final frame however that too can be done even now. I imagine in a couple years a commercial adaptation of this will come about, who knows maybe even a GPU based PRMan version? At the moment though it would serve far better for previewing of scenes, shaders, lighting and so on that do take up a huge chunk of time waiting to see if minute changes work, or don't. Sort of like Pixar's LPics or ILM's Lightspeed - though native REYES rather than GL equivalents. Again this has immediate practical use in previewing and changing scenes or assets before the final render is done - thus production times are reduced and it's is a bit more intuitive than waiting 10 minutes for a single preview.

One of the most impressive things to note though is that it was done with Blender and Mosaic, which if you follow my sig link will lead you to the very site where us users and developers have been pushing this for some time now. After all the website was created for this very reason.
This was good news for us, since pretty much this proves that even in research Blender to Renderman is valid. This is also the first time Mosaic was used and cited in a research paper.

Even if NVidia were to release this Fermi architecture in a few years, RenderAnts works NOW, it can be used in a matter of months by nearly any studio that uses Renderman. While in this case Blender and Mosaic were used for the demo, that was because of the availability of the 3D package, as well as the exporter - and that it costs nothing. The RenderAnts code itself is beyond our reach at the moment but we all know that in research this changes either by hiring the individual or tasking it over to software development teams in house that create a similar proprietary tool. Either way this can be obtained somehow by the end of the year, no need to wait. RenderAnts can work on modern GPU's, no need to wait for NVidia to build it, let alone the cost for such a device.

Personally I think this kicks ass.
