Light position for multi light setup
I'm building my own automated scanner to scan surfaces using the multi angle light setup. I'm doing extensive tests to see what will give the best result but I'm not sure what Shadermap assumes the light positions will be. I'm used to using a reflective ball in my scans to point out the lights position exactly, which does not just give the angle between the lights but also the height position of the lights. I guess my question basically is, what is the optimal height position to have your light setup in? Or what position does Shadermap assume the lights are in?
A bit more information on optimal light positions would be much appreciated.
