Logbook + Scratchpad

One of the experiments I did as part of the old project I have recently written about was about animating a 3D plot using OpenGL from PyQtGraph. The code was inspired pretty much to one of the PyQtGraph examples from its GitHub repository, where – for future memory – the main components are the following:

• A Qt QApplication as the container Qt app.
• A GLViewWidget as the main OpenGL view component.
• A GLGridItem to visualize a grid (not essential).
• A GLScatterPlotItem as the actual scatterplot graph.
• A QTimer to repeatedly call an update function, which includes two actions:
  • setData to plot the data points
  • orbit to make the camera spin around the view center (neat!)

I've recently revisited the example to put everything in a class rather than relying on globals. I'll publish it at some point.
