Stereo Photometrics module has nothing to do with gears, rather it offers the ability to capture 2D but create 3D all from your computer. The STL output reveals the basic stereo photometric technique that can be fun to play with.
Photometric stereo is a technique estimating the surface normals of an object by observing that object under different lighting conditions. It is based on the fact that the amount of light reflected by a surface is dependent on the orientation of the surface in relation to the light source and the observer. So by measuring the amount of light reflected into a camera it is then possible to calculate the space of surface orientations and create a 3D object. Gearotic attempts this process for you by using your computer and camera. Simply follow the 4 steps and voila! We do suggest you review the video tutorial for functionality and hope you have fun experimenting with it.
