In the October 2009 Slowinski at-large, I illustrate three different lane conditions in both 2-d and 3-d images.  Specifically, in the article, I discuss the importance of reviewing 2-D graphs and interpret these into 3-D as well as how to improve your visualization of micro-topography in lane conditions.   Since most individuals have not had the opportunity to see graphs in 3-D, in this month’s Slowinski atlarge, I present several patterns in three dimensions.  No special glasses are needed. It is an opportunity to truly see the contour, shape and topography of the pattern. To illustrate, I share with readers detailed two and three dimensional views of the 2009 “The BTM” Tournament (39 feet), the 2009 USBC Open pattern (40 feet) and a typical house shot (40 feet). Although the pattern lengths are similar, each pattern is very different, from a structural standpoint. Specifically, I want readers to see the differences between a 1-to-1 flat pattern and a typical house condition as well as an easier sport pattern.
