Joachim Bornemann created a
Rigol scope in Blender and published the file for it. Looks like in his Facebook posting he used the Eevee renderer for some of the pictures, which is nice for realtime raytracing while editing, but with the Cycles renderer it looks a lot better. I also added an area light above for more natural global illumination. My graphics card has not enough memory to render it with CUDA, but after 6 minutes heating up my CPU I got this:
I really like the BNC connectors and probe, and all the knobs and buttons, looks very realistic.
He has many other technical models, see
here.
What other good 3D electronics related models are out there?
