Illustration

To illustrate the method, we choose $ N=5$, and $ D=3$ so that $ N-D=2$ so that the data will always appear uniformly distributed when projected on a plane. Figure 5.8 shows the data as seen from the $ x_2,x_5$ plane after 4 and 20 iterations of the systematic method. The five facets of the valid region are caused by the manifold reaching the positivity limit of each of the five dimensions. Non-uniformity can be clearly seen for 4, but not for 20 iterations.

Later, we will discuss the difference between the systematic and the random-directions algorithm. But first, we must solve for the asymptotic mean.
