Relative world positioning with constraints
Head...hurts...help...trying to piece this all together from other threads but failing:
I have 2 world position points. I'm trying to determine a new point (aka CalibrationOrigin) that takes the X and Y from the LEFT point as the main camera looks at it, and the Z from the RIGHT point. But I'm not looking straight down the Z world axis. I'm looking at the points from wherever the main camera happens to be. And I don't want the vertical/Y angle of the camera viewpoint to matter - the point should just be straight down (world down) from the left point. How do I get that CalibrationOrigin point world position?
Bonus: Now I want to locate another object from the determined CalibrationOrigin above. The object is an X, Y, and Z offset from that CalibrationOrigin - but with the Z axis running from the main camera to the CalibrationOrigin (not world Z).
Yes I know I should spend a day studying vectors and coordinate systems again. :-)
