AI-Based Rendering Comes to Hollywood

by Ankit Patel

Chaos Group V-Ray, Isotropix Clarisse and Redshift Renderer embrace NVIDIA OptiX to dramatically change VFX workflows.

The next blockbuster coming to a theater near you may arrive sooner than ever, thanks to the new AI-based capabilities of the NVIDIA OptiX 5.0.

When incorporated into applications such as Chaos Group’s V-Ray, Isotropix Clarisse and Redshift Render, the software lets creative professionals visualize their designs or characters up to 12x faster.

Chaos Group, Isotropix and Redshift are among the first to experience OptiX 5.0’s abilities. Creative pros using their products will be able to see what final rendered frames will look like without waiting minutes or hours to see their work.

OptiX 5.0 paired with the newly announced TITAN V, the world’s most powerful GPU for the PC, lets designers, artists and other content-creation professionals iterate and innovate with incredible speed and massive performance — all on their desktop PCs.

“Thanks to its AI-driven denoising capability, OptiX 5.0 accelerates the Clarisse path tracer up to eight times!” said Sam Assadian, CEO and co-founder of Isotropix. “Combined with TITAN V, it will be a game changer for artists as they can make instant creative decisions on images that are very close to final renders — all from their PC.”

AI Rendering: Ready for Its Closeup

Visual effects company Double Negative, whose work includes such projects as “Blade Runner 2049” and “Wonder Woman,” uses Isotropix’s Clarisse renderer as its primary lighting and rendering tool. That’s because Isotropix has fully embraced the importance of enabling artists to make creative decisions as early as possible.

Having an early sense of the lighting in a scene is critical to an artist’s ability to accurately predict their final image, but this early view of the image is generally very noisy and hard to interpret.

“It was staggering to witness OptiX 5.0’s ability to create clean images that are genuinely representative of the final frame,” said Graham Jack, chief technology officer at Double Negative. “As Clarisse continues to refine the render, the denoiser converges on the final clean result in a smooth, deterministic way, meaning that artists are able to make detailed artistic lighting decisions considerably faster than they could before.”

Redshift Renderer, used by thousands of creative professionals and leading studios worldwide, plans to integrate OptiX 5 in upcoming product releases based on how the AI-based denoising greatly accelerates the removal of graininess from rendered images.

“With OptiX 5.0, NVIDIA continues to lead the way for the use of AI in rendering for design, character generation and the creation of virtual worlds,” said Panos Zompolas, chief technology officer and co-founder of Redshift. “Integration of OptiX 5.0 was a no-brainer for us — being both easy and free, it turbocharges the creative process and improves productivity for our users.”

Supercharged Rendering with NVIDIA GPUs

Software developers can freely use OptiX as an acceleration engine within their products for ray tracing. OptiX harnesses the power of NVIDIA Quadro and Tesla GPUs for workstation-class applications and NVIDIA TITAN or GeForce GPUs for high-performance rendering on the PC.

“We’re finding the NVIDIA denoising results to be very impressive on interactive scenes, giving artists a much quicker estimate of what their final result will look like,” said Vlado Koylazov, Chief Technology Officer at Chaos Group. “We believe this will speed the creative process while using our upcoming V-Ray GPU.”

OptiX 5.0 with AI denoising is available at no cost to registered developers starting this month.
