I’m wondering whether someone could help me out (again!).
I have a scene with many points in 3D space. Their positions are defined by input from a text file. I would like to be able to click on one of these points and use printf or the title bar to display a variable value from the input file. I understand defining selection names can be used to similar effect by hardcoding object names in the code, but I need a program that will work when I vary the number of points (or values of other variables) within the input file.
