RaiSim 2.13.0 lets you run robotics examples online and adds a fast fluid dynamics model
ChongZzZhang · x · 2026-11-03
The RaiSim team (Hwangbo Jemin) released RaiSim 2.13.0: official examples can now run directly in the browser, and a new fast fluid dynamics model computes buoyancy and drag.
The example site groups demos by feature (scenes, robots, rendering, sensors, dynamics, contact, terrain, fluids, mechanisms, benchmarks), each with clips from running programs. Examples come in three kinds: Server examples publishing a raisim::World via RaisimServer (viewed with rayraitcpviewer), in-process Rayrai rendering examples, and non-visual tools/benchmarks. They cover physics APIs, mesh import/export, OpenUSD loading and rayrai rendering/asset inspection; the legacy RaisimUnity and RaisimUnreal integrations are no longer supported.
