Typescript version of MarkovJunior, runs in browser (also in node.js).

• Everything have been implemented including isometric rendering, exporting the output as a .vox file, and node tree visualization.
• Every model from the original repository can be loaded with this project, but the output would be different due to different random seed implementation (dotnet builtin vs seededrandom).

• Install dependensies: npm i
• Start development server on localhost: npm start
• Build static site: npm build
• Run in node (writes result to /output): npm run cli

• I want to implement markovjunior in UE 5.2 as a plugin to the PCG component. MarkovJunior can be integrated as a special typed subgraph. UE 5.2 PCG is very data oriented - everything in a table where row is element and column is attributes. MarkovJunior output 2D/3D grid can be flattened to this table where row is pixel/voxel and column is the value. The result can be quite powerful, static mesh actors can be placed correspond to the output, graphs can be nested so the final output can be very detailed and hierarchical, and grid patterns can be broken as well by varying transforms to the gragh or generated actors. The only downside is this would take a lot of time and UE 5.2 is still in preview.

• This port is around 2x slower than the original repo (JS vs C#), but it doesn't affect the page much; even with 200 steps per frame there's hardly any FPS drop on most models. However, the slowdown is quite noticable on computation expensive calculations, e.g. uni/bi-direction inference.

• SokobanLevel1 takes ~10 seconds for the original C# code on my pc to reach the desired state, while it takes 20+ seconds on the web. I've tried JIT/unroll the rules into webassembly with generated AssemblyScript and it actually works: it gains a x2 speedup and the performance almost match the native C# version. The only problem is the load & compile time is terrilbe and it's incredibly hard to debug WebAssembly. I rolled back the commits on main and put the experimental stuff in the optimization branch, but I'm still pretty proud of this MarkovJunior rules -> AssemblyScript -> Wasm "JIT" compiler I wrote.

• Update: I wrote a precompiled wasm version and it works fine, and the runtime is reduced from 20+ seconds on SokobanLevel1 to ~13 seconds (not too bad I guess ¯\_(ツ)_/¯ ).
