WebIn order to find the final normal vector n, we must have images that have light emitting from left, centre, and right, thus we have 3 types of images by light angle, [0,1,2,3], [4,5], [6,7,8,9], thus 4 x 2 x 4 = 32 choices. Since finding z value for all choices and creating a 3-d rendering is very slow, we calculated all possible z values and ...
