I managed to render a OBJ (exported from a IFC) by adding some lights, but still wondering if there’s a proper light configuration to uniformly light the scene or I might be missing some color information.
Here you can see how the model is rendered in an online viewer vs my script.
On the other hand, I’m still unable to see any of my PCD cloud points (exported from XYZ), even despite of the lights. Not sure if it might be some incompatibility issue, but I can correctly render the PCD in other 3rd party tools.
Next you can find an html file of my tests, one of my ifc models (and the obj export) and a reduced PCD. Any tip in the right direction would be much appreciated.
