Here is a bunch of photorealistic pictures. There is each time a set of three pictures (photorealistic 3D model, normal photo, photorealistic vector) on the same theme. Can you tell which one is the Photo, the Vector or the 3D pic? I bet you can’t, so to ease you the task, here is the order in which the pics are: Vector, 3D and Photo. For those who don’t know, Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics.
