Alternative for a 3D viewer?

[bf5man]

Hello everyone, first of all, I want to congratulate you. This is a very cool idea and I will follow it with great interest.

I just wanted to make sure you were aware of this 3D webviewer project made with OpenCascade named CascadeStudio: https://github.com/zalo/CascadeStudio

There's a demo here where you can load STEPS files:
https://zalo.github.io/CascadeStudio/

I thought that maybe, it there could be something interesting as a basis for your own viewer.

HI, thanks for the feedback. I was not aware of CascadeStudio. It looks closed to some work that @erossignon made a couple of years ago with nodes (https://github.com/OpenWebCAD/node-occ/). I stopped exploring that alternative due complexity to interface with OCC and was focused on porting freecad to OCC 7.x kernel. I will definitely give it a try and have a look. Right now our viewer is "basic" and is getting as input OBJ generated from FreeCAD (we did adapted the Wavefront OBJ exporter for that purpose). I am facing some challenges to find the right balance for the meshing.
