I would like points that stay put on the screen. Here are some requirements: -stay pinned to screen coordinates -stay in the viewport -they may be freely moved -we may use them as reference points for other objects.
None of the methods in GGB meet these requirements (try it). Why? (Hint: there is no such thing as absolute coordinates). The points U1, V1, W1, Z1, however, do. Procedure:
- imgWhite = (blank, 32×32 pixel image). Set ObjectProperties>Position>Corner1 to Corner
- crn3 = Corner[imgWhite, 3]
- track the ratio Pixels/(GGB Unit): ppu = 32/x(crn3 - Corner)
