@davidr I think to move your center, you effectively need to move everything else. Generally I wouldn’t say the 3D capabilities of #PyQtGraph are as competitive as other offerings like #VisPy or #GlumPy. If neither package works than I would think doing something with the Blender API might be more suitable
Working on #vispy 2.0: trying to define a graphic server protocol. Here is a first example using the matplotlib backend (10,000 points). The #datoviz (https://datoviz.org/) backend is able to draw 10,000,000 points real-time using same code (https://github.com/vispy/GSP). If interested, drop me an email ( we'll try to organize a workshop this year to discuss different approchaes to #dataviz).
