He says the physics engine was written using HLSL compute shaders and that the game doesn’t rely on any vendor-specific rendering technology and is therefore optimized to run on any VR ready GPU, be it AMD or NVIDIA. Tann calls Chroma Lab a “particle physics sandbox,” and says that more than 100,000 particles are simulated in VR at 180Hz using a custom GPU accelerated physics engine. The game launched this week on SteamVR with support for the HTC Vive and Oculus Rift, and will soon come to the Oculus store. But what about simulations of the impossible, like commanding hundreds of thousands of floating pulsating rainbow particles?ĭeveloper Sean Tann has developed Chroma Lab to answer that question. VR gives us the opportunity to simulate the real world and its physical laws to step into situations that we couldn’t otherwise practically experience, like driving a racecar or flying a plane. This article, which was originally published on 3/28/17 and overviewed the game before it was launched, has been broadly updated with the latest information. Update (8/23/17): Chroma Lab is now available. One developer is taking interactivity to the extreme with Chroma Lab, a VR experience now available on SteamVR that lets you play with hundreds of thousands of simulated particles in real-time. VR design is still in the very early stages, but something that we know leads to immersion in VR is interactivity.
