How to create basic custom 3D triangle with Qt 3D?

Rayterex

Hello everyone. It is 2021 and I thought maybe there is more documentation and examples for Qt 3D, but looks like nothing has changed. Anyway, I plan to start digging through this black box. Does anyone know how to create basic custom 3D triangle or plane with C++/Python ? That would help me quite a bit

Yes. Fill an QAttribute with the vertices, add it to a QGeometry instance (typically it's your own subclass). Set the geometry you created to a QGeometryRenderer instance, which you can use as a component for an QEntity.

@mrjj Yeah. That last reply was exactly what I was looking for :)

This is pretty good explanation for me. Not as simple as I thought though

@kshegunov Thanks. This makes sense. I will try it out :)
