[Radiance-general] Get vector relationships between points

[Greg Ward]

Hi John,

I'm not exactly sure what you're asking.  It sounds like a simple math question.  The vector direction between a camera position and the sensor positions is just subtract one point from the other to get your vector.

Can you be more specific?

> Is it possible to use radiance to collect the vector relationship between points. For example i have a camera and 100 sensors points (to pass to rtrace). Can i get the 100 vectors from each sensor to the source? This is to aim each sensor to the camera face - rather than the zenith.
