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

As a shellfish, Patrick makes caviar. I'm glad I learned programming GPU physics. So many absurd things can be done with it.

This gameplay idea is about making cookies. You gently control the press to push out enough cookie dough.

Being a shellfish he is, Patrick is making caviar. If you created a physics engine, you would do these absurdistic experiments too.

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

Each particle is following the path of least resistance. Development of my physics engine is seriously delayed by me playing with fluid simulation.

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.

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.

How I created 3D soft body character from simple particle physics. It took a few months of intense computer science and inventing algorithms to trick a bunch of GPU computed physical particles into dynamically controlling a mesh.

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.
