001 / webgpu simulation & game engine

From simulator
to game engine.

One deterministic WebGPU runtime for high-fidelity physics simulation and shippable real-time games. Build the world once — train agents in it, then open the same scene to players in any browser. No install.

One deterministic runtime. No bridge between sim and game.

Physics, rendering, and scale share the same memory, the same scene format, and the same tick — so the world you train in is the world you ship.

01

Web-first

Built for the web. Zero-install deployment.

Open instantly in any modern browser.
02

Massive scale

High-density worlds. Thousands of entities.

GPU-driven rendering
03

Modern GPU

WebGPU renderer. Compute shaders. Bindless resources.

GPU culling
04

Deterministic simulation

Deterministic runtime. Fixed timestep simulation.

Rollback-ready networking
05

Tiny footprint

Fast startup. Small bundles.

Train in a world that obeys the same laws it ships with.

Skyforge erases the sim-to-game gap. Sensor models, contact dynamics and material response are identical headless or on screen.

Phase 01 · simulate

The simulator.

Spawn thousands of headless environments, collect a million episodes, and validate safety — every run byte-identical and replayable.

01Deterministic replay. Re-run any frame, any seed, byte-identical.
02Sensor suite.LiDAR, depth, segmentation, IMU & RGB as scene nodes.
03Headless farm. 10,000 parallel envs per node, no display.

Phase 02 · engine

The 3D engine.

A lightweight, zero-dependency 3D engine designed for real-time simulations and high-performance validation, powered by modern rendering and physics pipelines.

01Dual backend. Runtime selection of WebGPU with an automated WebGL2 fallback.
02GPU cluster rendering. A compute-shader meshlet pipeline (Nanite-lite) for frustum, cone, and LOD culling.
03Stable Cosserat Rods. Elastic rod physics solver supporting stretch, bend, twist, and contact constraints.
04Broadphase Spatial Grid. High-performance spatial indexing for 100k+ dynamic entities, reducing checks by 99%.
05PBR & IBL. Linear-space lighting, ACES filmic tonemapping, and image-based lighting reflections.

One project. Two lifetimes.

The name is the thesis: a simulator and a game engine sharing a single scene format, asset graph and physics tick.

Phase 01 · build & train

The simulator

  • Author world, materials & physics once
  • Spawn thousands of headless environments
  • Collect data, train policies, validate safety
  • Replay any failure frame deterministically
Phase 02 · ship & play

The game engine

  • Attach rendering, input, audio & netcode
  • Flip to the shipping graphics pipeline
  • Ship to any WebGPU browser — desktop & mobile
  • Hot-tune gameplay against the live world
