The interpolation method of surface mapping [how to change to nearest method]

[gourdchen]

When I draw a atlas in enigmatoolbox, the color of parcellations' edge will be strange, as follows:

I guess it is due to the interpolation before the image rendering, but I can't find how to change the method in the code. I am not familar with the VTK, it seems a difficult task for me. So, would you please help me to solve this problem? Thank you!

array_name=my_array.astype(int)
