Great VR experiences make you feel like you’re really somewhere else. To create deeply immersive experiences, there are a lot of factors that need to come together: amazing graphics, spatialized audio, and the ability to move around and feel like the world is responding to you.
Last year at I/O, we announced Seurat as a powerful tool to help developers and creators bring high-fidelity graphics to standalone VR headsets with full positional tracking, like the Lenovo Mirage Solo with Daydream. Seurat is a scene simplification technology designed to process very complex 3D scenes into a representation that renders efficiently on mobile hardware. Here’s how ILMxLAB was able to use Seurat to bring an incredibly detailed ‘Rogue One: A Star Wars Story’ scene to a standalone VR experience.
Today, we’re open sourcing Seurat to the developer community. You can now use Seurat to bring visually stunning scenes to your own VR applications and have the flexibility to customize the tool for your own workflows.
Behind the scenes: how Seurat worksSeurat works by taking advantage of the fact that VR scenes are typically viewed from within a limited viewing region, and leverages this to optimize the geometry and textures in your scene. It takes RGBD images (color and depth) as input and generates a textured mesh, targeting a configurable number of triangles, texture size, and fill rate, to simplify scenes beyond what traditional methods can achieve.
To demonstrate what Seurat can do, here’s a snippet from Blade Runner: Revelations, which launched today with the Lenovo Mirage Solo.
