Let p₀..p_N-1 bet a set of N image positions from which a surface patch, S, is visible.  The unit surface normal to S is n, and it's position is q.  For each image we calculate,

C_i = (q-p_i)/|q-p_i| . n

This is the Cosine of the angle between the surface normal of S, and the line-of-sight from the image to the surface.  C_i >0 since S can be seen from p_i, and C_i <=1.

Conflict occurs between all images from which S is visible.  The resolution strategy is to choose the image with the highest resolution value R, defined as,

R_i = C_i + T_i

where T is the image texture priority.
