InfiniPaint

InfiniPaint is a collaborative, infinite canvas note-taking/drawing app. Unlike many other infinite canvas apps, although there is a specific zoom-in level limit, there is no zoom-out limit (at least up until the point your computer runs out of memory). This means that this app is very good at things such as drawing sketches of the solar system to scale, or just drawing any massive objects with tiny details. Of course, even though this is a feature, this app is also perfectly well suited for use as a normal canvas.

You can try the web version of this app at infinipaint.com (requires a WebGL2 capable browser). The web version was compiled from C++ to Javascript using Emscripten, and may contain some bugs, so if possible, please consider downloading the native version for a better experience.

This program is a work in progress, so I cannot guarantee that files created in this version will open in future versions.

This app was inspired by Lorien, another great infinite canvas program.
