Maybe this could be from triangle indices being clockwise instead of counter clockwise?

[kylebarron]

Yes, this is because triangle indices were clockwise. (py)Martini creates counter clockwise triangles, but with the coordinate origin being in the top left. To make clockwise triangles with the origin in the bottom left, you need to set flip_y=True on rescale_positions. Ref #14
