# Simulated people, spaces, and systems in a game engine. > Digital Twin Simulation by Dream Awake Labs. Simulated versions of people, spaces, and systems in a game engine: computer graphics and physics precise enough to train models, test experiences, and run a venue before it is built. The problem: Real capture rigs, real venues, and real crowds are expensive to run and impossible to label exactly. A simulated version is only useful if its cameras, physics, and timing match the real one closely enough to trust. Who it is for: For teams that need to train a model, test an experience, or plan a venue against a version of the real thing that exists only in software. ## Every camera sees the same instant The synthetic-data pipeline we built for multi-view human reconstruction is a digital twin of a capture studio. Calibrated color and infrared cameras render every view on the same engine tick, with intrinsics and extrinsics written into every output, so a frame from one camera lines up with the same instant from every other. The same idea runs the venue side: Spatial Venue is exercised by simulated players that fill sessions without hardware, Spatial OS has a simulator seam for running an experience against fake devices before the real room, and Agent City plays deterministic scenarios through the real adapters, so a demo and a test are the same thing. - Pipeline diagram in six numbered stages: digital humans from stock engine presets; procedural variants of identity, outfit, and hair with retargeted body motion; a highlighted multi-camera rig rendering every view on one engine tick with calibrated color and infrared cameras; a cloud render farm; ground-truth passes for depth, optical flow, normals, albedo, segmentation, boxes, skeletons, and meshes; and a content-addressed asset registry. A tuning loop below compares renders with reference video. (A capture studio in the engine: calibrated cameras, one tick, labeled output.

What you get: The running simulation, the comparison, and a written note on what to calibrate or build next. What you bring: - What the simulation must match: cameras, devices, players, or a workflow - Measurements from the real thing to compare against - The engine or runtime you already use, if any - [Discuss a simulation project](https://dreamawakelabs.com/start?from=%2Fdigital-twins) - Email: hello@dreamawakelabs.com ## Other areas of expertise - [Story & World Intelligence](https://dreamawakelabs.com/story-intelligence.md): Film search, AI characters, and interactive stories. - [Interactive & Physical Experiences](https://dreamawakelabs.com/experiences.md): Experiences that respond to the people in the room. - [AI agents & business automation](https://dreamawakelabs.com/agents.md): AI agents for everyday business work. - [Synthetic data & digital humans](https://dreamawakelabs.com/synthetic-data.md): Synthetic data for training and testing AI. - [Multiplayer game development](https://dreamawakelabs.com/multiplayer.md): Multiplayer games and the servers behind them. - [Agent-Ready Web Applications](https://dreamawakelabs.com/agent-ready-web.md): Web apps for people and AI agents. - [Custom engineering](https://dreamawakelabs.com/software.md): Engineering for the parts no off-the-shelf product covers.
