Show HN: SlamDunk: A user-friendly 3D visualization library

5 robertleoj 0 4/10/2025, 3:52:11 PM github.com ↗

Hello!

I am working on SlamDunk, a lightweight and easy-to-use visualization library built with C++.

I started the project out of a personal need - I am in the process of learning about SLAM (simultaneous localization and mapping) and found the lack of visualization tools very limiting.

This is why I'm making this tool - it aims to allow the user to make powerful live visualizations without a lot of boilerplate and fiddling with rendering loops and computer graphics.

SlamDunk is built with OpenGL and ImGui, so it is very lightweight.

Please let me know what you think!
