01 · SIMULATE VisuTwin Sim

Deterministic by default.

A C++23 simulation runtime for fields, physics, DEVS and agents, on the CPU or accelerated with CUDA and Metal Compute.

02 · RENDER VisuTwin Canvas

Brought to life on the GPU.

A physically based real-time renderer on native Metal and Vulkan, built to embed in digital twin and scientific applications.

03 · EMBODY VisuTwin Robotics

Robots and living systems in motion.

URDF and MuJoCo pipelines with forward kinematics and in-situ data feeds, from surgical instruments to a flying fruit fly.

Simulate. Render.
Embody.

Three native C++23 projects, one digital twin workflow, from the model to the pixels to the robot.

02 / UNDER THE SURFACE

Purpose-built for demanding worlds.

Deep technology.
Clear possibilities.

Rendering, simulation, and scientific data belong in the same conversation. VisuTwin Canvas brings them into one native framework.

01

Built close to the GPU.

A C++23 engine with native Metal and Vulkan backends. Physically based forward rendering, clustered lighting, and a composable shader system.

02

Time, on your terms.

A deterministic fixed-timestep pipeline keeps simulation and visualization synchronized. Designed for digital twins and scientific computing.

FIXED TIMESTEPIN-SITU
03

Complexity in motion.

GPU skinning, morph targets, and animation state graphs. Gaussian splatting and GPU-simulated particles extend what you can visualize.
