Abstract

Fetch is a measure of unobstructed wind exposure over open water. Depending on prevailing conditions, it may necessitate considering wind exposure from many directions. Applications in geography may require visualization of fetch over an entire body of water. Impossible by hand and computationally demanding even on a computer, this paper describes a new method which accelerates the process to interactive speeds. The speedup is obtained by reformulating the problem to one of graphics rendering and making use of commonly available computer graphics hardware through OpenGL, a widely support graphics standard.
