The problem PLACKY solves

It solves the problem of finding out similarity or to check plagarism between two or more 3d models

Challenges we ran into

First of all we had to figure out a way to make machine understand 3d models. Representation of 3d models is usually done in formats like point clouds but problem with point clouds are that they are asymmetric and they do not carry internal structure information.
We projected 3d objects onto 2d planes at different algorithms and used algorithms on 2d planes that were capable enough to handle skewness and distortions.
