Unity Bitmap Drawing
A downloadable tool
Real-time bitmap drawing for Unity3D.
Extremely CPU efficient, zero garbage allocation per frame, works well exported to WebGL.
I am using this in my own project, so development is active. The performance critical parts are finished, but usage examples, documentation, and unit tests are lacking. The sprite pooler isn't very good, but is fine for holding a few intermediate brushes while you composite an image.
Open to improvement requests and support queries.
