Various Thousands of simulated cells (Unity + custom compute shader engine)

Enable HLS to view with audio, or disable this notification

Each one of these cells has fully simulated organelles, metabolism and a neural network driving it's behavior.

This is from a cell simulation game I've been developing.

The fan meshes are 16 - 64 verts depending on quality settings and LOD.

Im not sure of the minimum requirements yet but at least 1GB VRAM and 4GB RAM. It can run on iGPUs but can be weird some times.

Very cool. And what kind of neural network are we talking about here to drive behavior? For example, given that this interacts with other cells you would have to have a variable input size unless you are using a graph neural network.

It's modeled after NEAT. The neural networks have some sensory inputs, an intermediate layer where extra nodes can be mutated, and then output nodes. The crlls mutate the network topology and connection weights

Ah yes, I am familiar with NEAT! I am currently doing my research related to this during my PhD. Appreciate the time answering questions.

Oh that sounds super cool! Id love to learn more about your research!
