hi , i been thinking on this one for a while,
the idea is to use a cam to object track someone on stage and use this to control a moving head spotlight.
can any one give me any pointers, i think i can handle the object track bit to give me X & Y the Z will be a set value of the persons hight. i can do the dmx out bit.
I just need help with all the messy maths bit in the middle that will turn the XYZ of the target in to Pan/Tilt and possible iris to send on to the moving light.
