Made tank tracks in my physics engine. The ground is made of particles, so it's realistically deformable. The whole thing runs on GPU, thanks to compute shaders in Unity.

Out of sync cookie maker. I spent half a year programming this physics engine, and now having fun creating surrealistic machinery with it.

Flesh, bones, muscules, joints, tendons - all simulated. I'm after 100% physical characters in games. This arm is controlled by 2 gamepad sticks. But I'll have to run genetic algorithms to let characters learn complex behaviors as a response on simple input.

Punching various objects

Streams of liquids impact, soft to hard.

Trying different weapons against a wall. In fact, testing the editor. I didn't expect it to require so much time and effort. But it was worth it. Makes creating levels fast. And players will be able to create content as well.

What if I spin like crazy while shooting laser. The cave must shatter.

Besides trying different gameplays with my physics engine, I did some random funny looking simulations just out of curiosity.

Beware! He added mining robots!

For this simulation I used the algorithm I invented, to generate a mesh around a set of physics particles. The particles are used as bones. Skinned mesh math runs on GPU, updates the mesh, then it's rendered, without any data sent GPU->CPU. Marching cubes would be easier though.

Each physical particle here is visualized by a sphere. It's ineffective, but was fast to implement. I'll replace it with marching cubes, to have only 1 mesh and 1 draw call for all particles.

How to build a mesh around a cloud of simulated particles? Red spheres -> physics particles. Yellow dots -> vertices. Vertices push each other, but kept near physics body. So, they form 3d lattice under pressure. It's then tetrahedralized, and outer triangles form the mesh.

Soft body character, controlled by player. Mesh is skinned by physics particles. Connections between the particles act like muscules.

Applying high pressure to check how stable the simulation.

Stress test for the simulation. Plenty of soft bodies interacting with each other.

Making the matter tough is also a stress test, because with stronger force between particles, the simulation can explode. But it stood strong.

Someone dropped some math in a transcendent protodimensional 5∞90 GPU, it started self-organizing. That's how our universe emerged. And here's me having dropped some math in a less sophisticated GPU:
