I’d like to introduce HelloTriangle, an online platform for Python-based 3D modelling, mesh generation and analysis. You can write a few lines of code, generate or import a mesh, manipulate it, analyse it, and instantly share it via a link.

I built HelloTriangle because I often ran into barriers when doing advanced, mesh-based 3D modeling: steep learning curves, sometimes tricky installations, juggling multiple tools, or using expensive software.

Another frustration was sharing results: 3D insights often get lost when all you can send are 2D screenshots, since others don’t have the software to view your models, or because you don't want to share the underlying files.

You can try it here: https://www.hellotriangle.io

I’d really love your feedback — especially on use cases or missing features you’d want for a smoother Python-based 3D workflow.
