Genesis Physics Engine: A Guide With Examples

Genesis is an AI physics engine capable of producing highly realistic simulations. It’s impressively fast and can generate interactive 4D worlds. Key use cases include robotics and physics experiments.

In this blog, I’ll provide an overview of Genesis, showcase a few examples, and compare it with other video generation tools like Sora. A coding tutorial on Genesis is coming soon, so stay tuned!

What Is Genesis?

Genesis is a physics platform made for a wide range of uses, including robotics, AI that interacts with the real world, and AI that works with physical objects. Genesis is the result of a big collaboration between more than 20 research labs over two years.

Unlike regular video generators, Genesis was designed specifically as a physics engine. It combines different physics tools (like rigid body, fluids, and soft materials) into one system. This makes it capable of handling various real-world simulations. We could use Genesis as a:

1. Physics engine: It’s a super advanced physics simulator that can handle all kinds of materials and physical events, completely rebuilt from scratch.
2. Robotics simulator: It’s lightweight, super-fast, easy to use with Python, and perfect for simulating robots.
3. Rendering system: It creates realistic visuals very quickly and with great quality.
4. Data generator: It can take natural language descriptions and turn them into all kinds of data.

Compared to older simulation platforms, here are some key features of Genesis:

1. Incredible speed: Genesis is extremely fast, simulating over 43 million frames per second (FPS) for a robotic arm on an RTX 4090. That’s 430,000 times faster than real-time! Genesis is the fastest physics engine in the world, up to 80 times faster than other simulators like Isaac Gym or Mujoco, without losing accuracy.
2. Works everywhere: It runs on Linux, MacOS, and Windows, and supports different hardware, including CPUs, Nvidia GPUs, AMD GPUs, and Apple Metal.
3. All-in-one physics system: Genesis combines many physics tools into one system, simulating rigid bodies, liquids, gases, deformable objects, and more. It can handle a variety of materials and how they interact.
4. Supports all robots: Robotic arms, drones, soft robots, legged machines.. You name it, Genesis works with a wide range of objects and supports popular file types like .xml, .obj, .stl, and others.
5. Python-powered: Genesis is built entirely in Python, which is simple to use and customize.

Genesis Video Examples

Genesis can simulate things like object motion, character movements, and interactions with incredible accuracy. Let’s take a look at a few examples shared by the Genesis team.

Creating 4D dynamic worlds

Genesis uses its advanced physics engine and AI tools to build detailed, realistic virtual worlds that include movement and interaction in 4 dimensions. These worlds can be used to create accurate videos, animations, and other data for simulations. It can even generate camera movements and object actions that feel natural and consistent.
