Background

Lascaux Sketch was originally a Java Applet I wrote back in 2002 used on 2draw.net. This is a new version built from the ground up using TypeScript and WebGL.

Technical stack

• TypeScript for type-checked JavaScript
• React for UI
• Create React App for scaffolding (this may change to Next.JS)
• Vercel for deployment
• WebGL for graphics compositing
• Dexie for IndexedDB-based browser local storage
