How to create 3D of rough diamond? i am going to develop a new machine which has one camera
for capturing images and one motor which rotates the diamond after capturing image. After this process i have 100 contours of rough diamond images from different angles, now i want to create 3d model of it same as real rough diamond object.

i am about to finding library like pass every images contour one by one and it will returns the 3d model of that contours.

please suggest me about these types of library or logic..

thnx.
