Classic mesh simplification preserves an object’s appearance for rendering purposes, but what if the goal is simulation, where objects can be twisted, bent, or folded? This method simplifies the mesh for simulation by exploring the vastly larger space of intrinsic triangulations, leading to more than 1,000x faster results on common tasks such as computing geodesic distances. In their presentation, Surface Simplification Using Intrinsic Error Metrics, Roblox researcher Hsueh-Ti Derek Liu and colleagues from Carnegie Mellon University and University of Toronto, propose a method to simplify intrinsic triangulations. Rendering these complex environments requires solutions for real-world effects like rippling or twisted fabrics, uneven terrain, etc. Optimized RenderingĪs 3D worlds become more realistic, structures and terrains become increasingly complex. Read more about the work we’ll be presenting below, and see a schedule of where to find us at SIGGRAPH. Because we support a global platform with hundreds of millions of users, every aspect must scale on both the client and server-side and support any device from older phones to the latest AR/VR headsets. Our newest work enables hair, fabrics, objects, and landscapes to react to movement, collisions, and wind just as they would in the real world. We advance 3D content creation, physical simulation, and real-time moderation using a combination of first principles and artificial intelligence (AI) techniques. Roblox Research pursues the fundamental science of technology for our social 3D platform, with the goal of connecting a billion people with optimism and civility.
