Hello everyone, I recently introduced my voxel playground, a ray-traced voxel engine made with cellular automata in mind. However, so far the voxel map itself is quite barren. So I set out to populate the world in interesting ways. For a previous project, I had used Wave Function Collapse, and I thought it would be fun to try to apply it to full 3D world generation. I have implemented two distinct versions of the algorithm.

I have been playing the new Mario Kart World game recently. During the water sections, I noticed that bob-ombs could cause large waves to appear that interact with the players. I have wanted to work on a technical art project for a while now, so I decided to implement a version of their interactive ocean system for myself. Additionally, I implemented many other effects featured in the latest Mario Kart installment, such as item boxes, boost panels and tire tracks in the sand.

I have created a new voxel engine that is designed to handle fully dynamic scenes. Inspired by classic falling sand games, my aim was to create a system that can handle many unique interactions between different materials. The world is rendered using direct voxel volume rendering, such that changes to the world are immediately reflected on screen. As we are updating upwards of hundreds of millions of voxels, many times per second, the entire simulation is run on the GPU using compute shaders.
