A Multiphysics Engine on the GPU
Nexus is a cross-platform GPU-accelerated multiphysics engine for Rust. The whole simulation pipeline runs as compute shaders written in Rust with Rust-GPU and compiled to SPIR-V, executed through WebGPU (on Windows, macOS, Linux, and the browser), or through Metal, Cuda, or CPU.
Rigid-body dynamics is available today, with colliders, joints, articulated multibodies, and URDF/MJCF robots. So is MPM, for deformable objects, granular materials, and fluids, with one-way coupling from rigid-bodies. Other solvers — DEM for granular media, FEM, etc. — are work in progress.
GPU-Accelerated
The whole physics pipeline runs as compute shaders — thousands of bodies in real time.
Cross-Platform
WebGPU on Windows, macOS, Linux, and the browser. CUDA, Metal, and CPU backends too.
Shaders in Rust
Compute shaders written in Rust with Rust-GPU and compiled to SPIR-V.
Rigid-Body Dynamics
Boxes, balls, convex shapes, trimeshes, heightfields, joints, and multibodies.
Material Point Method
Deformable objects, granular materials, and fluids, coupled with rigid-bodies.
Robotics-Ready
Load URDF and MJCF robot descriptions, including MuJoCo Menagerie models.
Python Bindings
The 3D engine and viewer are also available from Python as the nexus3d module.
