Better Denoising for RenderMan 21
Developed by Disney for Big Hero 6, the Denoiser was used with incredible results on Finding Dory where the average frame rendered ten times faster. For version 21, the Denoiser received several important upgrades ... Disney optimized the Denoiser to handle lots of fur and hair to handle the demands of Zootopia, while at Pixar the Denoiser was extended to support GPU acceleration, reducing the time required to denoise a feature film frame to seconds.
For physically based rendering in general, it can take a long time for a render to converge to a completely noise free image, but RenderMan's new Denoiser can dramatically reduce render times while delivering images of the highest quality. Now you can render faster with fewer samples, resulting in an initially noisier image which is then transparently filtered by the Denoiser, producing a high-quality final image. In fact the Denoiser is capable of reducing render times from 2x to 10x, and can handle shots with extreme motion blur and depth of field. Finally the "make pretty" button has arrived!
Developed by Disney
This amazing technology was originally created by Walt Disney Animation Studios and Disney Research for Big Hero 6 and as a result has already been tested and proven in feature film production. Today the Denoiser is also an invaluable component of Pixar's own pipeline for the upcoming animated feature film, Finding Dory.
"The new denoising technology currently being used in our upcoming feature,
‘Finding Dory,’ has been incredibly valuable, allowing us to compute final frames up to ten times faster. We could not finish this production without it.“
John Halstead, Supervising Technical Director of Finding Dory
This denoising technology is another example where RenderMan is able to channel the combined technology resources of The Walt Disney Company.
Using the Denoiser couldn't be easier. The denoising technology can be enabled with a flip of a switch, and the process can be completely transparent. When RenderMan renders an images, extra channels are written out which the Denoiser uses during a post process to intelligently remove noise through statistical filtering and preserve the details of the original image. The post process is quick, at approximately 2 to 4 minutes on a full 1080HD image. Because the Denoiser requires extra channels, the pre-denoised image can be much larger, but the requirement for additional storage is the only penalty for using the Denoiser.
Animation? No Problem.
The Denoiser can handle tricky animated sequences using "cross-frame filtering" mode, where the filtering for each frame also takes into account the pixels from the frames immediately before and after.
The Denoiser provides many knobs and buttons for controlling precisely how the Denoiser filterers an image, so whatever special challenges your scene presents, the Denoiser can be fined tuned to generate the best results possible.
"After the incredibly positive reception of MPC's first major movie release rendered in RIS: The Jungle Book, we are extremely excited about the many new features in RenderMan 21. With increased rendering performance, advanced materials & lights, and all around refinements, it continues to validate our choice as MPC's main renderer and it will be used on all our films going forward.”
Chief Technology Officer, MPC
"RenderMan's RIS is an amazingly powerful tool that enabled us to meet the technically challenging demands of Piper and achieve its distinctive show look. We discovered on several occasions that a technique we thought previously infeasible, such as instancing millions of modeled refractive sand grains, or putting a thin layer of rippling water over much of our set, was now in reach and gave us the look we were after. Live Re-rendering in particular saved us enormous amounts of time.”
Supervising Technical Director for Piper at Pixar
"This truly brings the future of fully photorealistic ray traced rendering to RenderMan. We did tests with the production assets from one of our latest movies and were completely blown away by the speed and how interactively we could preview and render these assets. The RIS based integrator is going to change the way we work, with more scalable rendering and faster results.”
Global Head of Lighting at MPC
"Pixar has really outdone itself with RIS. The speed, quality, and ease of use that the new substrates bring are mind-boggling. You can setup a character in a shot fully knowing that the nature of the shaders won't change with lighting. It speeds up the look development process significantly.”
