reproducing Fig 3: t-SNE embedding of 3DMatch descriptors

[caifazhou]

Dear Mr. Zeng,
I am very interesting to reproduce Fig 3 as your repored in the paper. I've tried to use the implementation of t-SNE in sklearn, I have a problem of visulizing the diemsion reduced features into different colors. Can give me some hints for reproducing the figure? Or do you mind sharing your code for this figure? Thanks in advance.
