Topics Covered:

• Revisited Mqtt Wildcard retrieval and looked at an alternative approach to using a MutableDictionary: use the Sampler [Reactive] to get all items received since the last frame and insert those into a Dictionary
• Overview of projection mapping solutions available via the VL.BadMapper package: 
  • 2d mapping using homography approach: QuadMapping and CircleMapping nodes to crop parts from a texture and map those to a screen using 4-point homography distortion 
  • 3d mapping using projector calibration: Using the ProjectorCalibrator extension to compute the view/projection matrices at which the projector is placed relative to the screen 
  • Simple mapping that works perspectively correct from the position of the projector
  • Reprojection mapping that allows to specify a different Spectator view for which perspective illusions will work.
