Description
I've been building a level editor for Quake 3 that runs entirely in the browser: Radiant-style layout, brush and patch editing, CSG, terrain sculpting, and entity editing. It opens and saves .map file and you can play the maps you build directly in the browser using a webassembly build of ioquake3.

Could you build this?
No Building a full browser-based 3D level editor with CSG boolean operations, terrain sculpting, custom .map format parsing/serialization, and compiling legacy C/C++ BSP engines (q3map) and game engines (ioquake3) to WebAssembly requires deep systems, graphics, and compiler expertise.
What it would actually take: Requires WebGL2/WebGPU rendering pipeline, custom 3D brush and constructive solid geometry (CSG) math libraries, and Emscripten pipelines compiling legacy C game engines (ioquake3, q3map) to WASM. The hardest parts are robust 3D polygon clipping/CSG without numerical instability and coordinating virtual filesystem (VFS) memory buffers between the browser editor and WASM compilers.
Discussion
20 comments analyzed.
Competitors mentioned: Quiver (classic Quake 3 map editor), Q3Radiant/GTKRadiant, Cube Engine/Sauerbraten, Stepmania
Concerns raised: Quick Play functionality broken in production, Mouse capture not working on Windows 11 Firefox, TGA image format support issues with shader loading, Unknown surfaceparm errors during map compilation, Uncertainty about active Quake 3 community interest
Feature requests: Support for q3map2 instead of original q3map, Better error messages/debugging for map compilation failures
