WebJan 1, 2024 · The input to this script is the 32-bit float stack produced from the Photometric Stereo plugin and it can produce any novel lighting direction with a mouse click. A Working Example. Step 1: Download the tiff stack pedernal. This is a stack of 31 images of a painting surface with the advanced formation of soap protrusions. 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 ...
