Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs.

More accurately, they're density fields, but, potato-tomato. Bonsai has undergone a large rewrite over the last couple years that's nearing completion. A world edit is defined as a bunch of SDF parameters which get projected/rasterized into the voxel grid by a shader on the GPU.

One neat thing about SDFs is they've been thoroughly researched and documented by a guy named Inigo Quilez, and they have a lot of nice mathematical properties. For example, you can do a smooth union of arbitrary SDFs to get nice rounded contours where shapes join. I've written every system from scratch, all the way from the memory allocators and font rasterizer to the collision detector and simulation loop.

I even wrote a metaprogramming language as a replacement for C++ templates, which is a whole other story. IIRC the only external dependency is the C runtime library for starting the process and my very occasional use of variadic functions arguments. For a long time, an explicit non-goal of the project was to ship a game.

It sounded insane to me to write an entire 3D engine and then ship a game. As it turns out, I've gotten it to the point where I can actually make a game. I've got a start on the game systems in a closed-source repo, and hope to have a steam page for it by the end of the year.

I'll do some shameless self-promotion and leave some links here for anyone interested in looking at the engine, language code, or some pretty pictures.https://github.com/scallyw4g/bonsaihttps://github.com/scallyw4g/poof I'm building an open-source way to fill U.S. immigration forms without fighting clunky PDFs Github: https://github.com/athos2113/fillvisa-os Demo: https://fillvisa.com/demo/US Immigration still relies on outdated XFA PDFs - you can't fill them on your browser.
