Is there a built in dot product function, I see that there is one for vcross() and vlen() but no vdot().
I am implementing an experimental lighting model, as such, I need the incident vector (denoted as I) from the camera position to the point currently being shaded. The vector I forms part of the formula in the lighting calculation.
If there is such a vector I, is there a way to find out the position of the current camera so that I can calculate the vector I myself?
