Avara3D is a real-time 3D visualization and physical simulation engine.

Avara3D combines real-time rendering, rigid-body physics, fixed-step simulation, and cross-platform application support into an elegant C++20 API.

WebGL lighting is broken in macOS versions prior to macOS 26 Tahoe due to an apparent graphics stack bug.

Fixed-step simulation

Bounded catch-up, pause, reset, single-step, and observable discarded time.

Rigid-body physics

Dynamic, static, and kinematic bodies with collision detection, impulses, material response, and HACD-based convex decomposition.

Scene-oriented C++20 API

Rendering, physics, input, and simulation are exposed through a compact scene-based application model.
