## What it is
Sketchbook is a simple web-based 3D game engine built on three.js and cannon.js, focused on third-person character controls and gameplay mechanics like vehicles and character AI. It is a TypeScript playground for recreating conventional third-person game mechanics in a general way, with scenes defined in Blender and loaded as glb files.

## Use cases
- build a third-person character controller in the browser
- prototype 3D gameplay mechanics with three.js and cannon.js physics
- create drivable cars, airplanes, and helicopters in a web game
- load Blender-authored glb scenes into a web 3D world
- experiment with raycast capsule character controllers and character AI
- learn how modern third-person game mechanics are implemented

## When to choose
- you want a lightweight, readable TypeScript codebase for third-person 3D gameplay experiments
- you need a starting point to fork for a small web-based 3D game or demo
- you want to study implementations of character controllers, vehicles, or character AI

## When to avoid
- you need a maintained engine with active bug fixes and support (the project is archived)
- you need production-grade performance, tooling, or a full editor
- you want first-person, 2D, or multiplayer-focused game development
- you prefer a large ecosystem with extensive documentation and community
