When you're working for months on your physics engine, sometimes you just do random things like this, without any particular reason.

I'm more algorithms guy than a designer. I managed procedurally visualize cities in my civ-alike game. But they're rather on the ugly side. And it's hard to say how to fix it. Though, it will be in harmony with the ugly city management UI I'm about to create.

Fluid particles in a radial force field form spiral arms. Without fluid solver it's just a shapeless cloud. I was suprised. Fluid solver has properties pure gravity doesn't have. Yet, real galaxies driven by pure gravity look similar. As if spacetime was fluid on galactic scale.

Recently implemented weapons. Feels so good to test this stuff. Why don't games have more simulated physics? It's so fun to play with! Compute shader is 3K lines already. 99% of game logic runs on GPU.

I'm making a physics simulation game. It's computed on GPU, allowing big dynamic destructible world. I haven't decided on gameplay yet, this video is a collection of experiments.

Example of interaction between entities, implemented in my physics engine: - soft bodies, skinned by bones, controlled by player - static ground - fluid - solid matter made of particles

I implemented physically realistic jet engine. The flame is fluid with lifetime. It interacts with objects, affects them - much better, than the fake VFX one I used previously.

What an awkward bug! There's no player input, no forces. I just made a liquid simulation algorithm, and it's trying to work. Yet the behavior somehow is so sophisticated, a combination of chaos and order. Like it's trying to self-organize into something, but fails.

Surprizingly, this trivial gameplay is entertaining. I started recording this video, but then just kept buldozering soil for fun. We have physical intuition, and it's valid inside this simulation, you just know how to adjust the plow right, and it works.

Today my curiosity led me to a question: what happens when center of galaxy explodes. The camera rotates with the galaxy. The galaxy is modelled in my physics engine as fluid in a force field.

Have you heard that falling to water from high altitude is damaging? It's not intuitive, water is soft and malleable. Let's simulate it! A box made of hard matter falls into a pond from higher altitude each time. Will the box withstand the impact?

Implemented tools to create and remove ground. Very simple for now: no precise aiming, no VFX. I made this patrickmobile as a temporary means to move in the game world, until proper limb based locomotion is implemented. The game will definitely include digging.

At some point I considered making a molecular constructor as a little sandbox game. I enjoyed putting together particles with different properties, to form stable objects. But it made sense as a VR game, and I didn't have a VR set to test it, so didn't push this proto further.

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.

For my genetic algo project I tried using modified AVBD method (on the video). It's FAST, great at resisting pressure and maintaining volume. But GA would always feed on parazite pos correction energy, to move for free. So, after all I used physically fair solver by Erin Catto
