Constructing a 2-dimensional contour. The top left plot shows a base of type 1, a circle of radius 1. The top right shows the base with one Gaussian bump of type 3 in direction \(\left (\sqrt {2}/2,\sqrt {2}/2\right)\), the bottom left shows the final contour with another Gaussian bump in direction (-1,0). The bottom right plot shows a sample of size n=1000 from this contour using the method described in Section 3
