Description
process demo - https://i.redd.it/fbhlwsq1gcmg1.gif render demo - https://i.redd.it/smddwtryhcmg1.gifI love making creative software. I spent a few years making pixel art software but recently have gotten into 3d animation and 2d animation and really wanted a way to realize crazy ideas.Blockbench didn't feel quite right, spline is super well made but felt catered too much to just idle website animations, and I really didn't want to fall down a master class in Blender just to make some silly stuff. While I'm definitely not discounting Blender's literal powerhouse functionality, I wanted something smaller, easier to adopt, and something directly inside the web ecosystem. So that when I want to make assets for silly games I won't have to jump through any hoops to make everything match up and render nicely. So, I made Topomaker (tentative name).It's sporting your basic 3d modeling, coloring, and animation. It's currently supporting exports to mp4's and gifs for sharing, and then glb's and obj's for making games in threejs.I literally just started it a couple weeks ago so there are probably tons of bugs, so maybe not for anything serious, but feel free to play around with it and let me know what you think!

Could you build this?
Partial A basic Three.js 3D viewer can be vibe-coded, but an interactive 3D modeling and animation editor requires sophisticated geometric mesh manipulation, UV mapping, and inverse kinematics.
What it would actually take: Building a full browser-based 3D modeling tool requires WebGL/WebGPU with Three.js or Babylon.js, alongside custom data structures for half-edge mesh representations to support extrusion, beveling, loop cutting, and subdivision surfaces. It also demands a custom keyframe animation engine, bone rigging transformations, and 3D gizmo interaction logic.
