This tells me that the position of the sun in Indigo is actually some fixed distance from the scene origin. So my question is this:
Given:
- Vector from camera to sun (direction only, not length)
- Vector from scene origin to camera (direction and length)
Determine:
- Vector from scene origin to sun (length not required)
This is probably very easy but I am a bit rusty on my 3D math...
