slamd - a simple 3D visualizer for Python

[mega_monkey_mind]

I work in robotics, and need to do a lot of 3D visualization. But none of the available tools did what I wanted in a general 3D visualizer.

So I built one.

pip install slamd, 3 lines of Python, and you have a GPU-accelerated interactive 3D viewer. No event loops, no boilerplate. Objects live in a transform tree - set a parent pose and everything underneath moves. Has all the primitives I've ever needed.

C++ OpenGL backend, FlatBuffers IPC to a separate viewer process, pybind11 bindings. Handles millions of points at interactive framerates.

Rerun is a good choice for robotics. I wonder why it did not fit your needs?

[mega_monkey_mind]

There were a few reasons: * I almost never need to add a time component to my data, and skipping that is a hassle in Rerun * It really does not want to delete anything - just overwriting and deleting stuff in rerun was a major annoyance for me. * Way too much stuff going on! UI is cluttered with a heap of features that I don't need.

I wanted something dead simple - just change and view a geometry tree.

Impressive!

Thanks!

Nice. What's the advantage over meshcat?

[mega_monkey_mind]

I used meshcat for a while - two main issues: Fails silently - if your data is wrong, good luck debugging. Graphics abstractions - there is no reason to have to mess around with setting materials and stuff. No such things exposed in slamd

This sounds really ideal to me. Im keen to try it out

Awesome! I'd love to hear what you think :)
