books.google.com - Until recently, all of the interactions between objects in virtual 3D worlds have been based on calculations performed using linear algebra. Linear algebra relies heavily on coordinates, however, which can make many geometric programming tasks very specific and complex—often a lot of effort is required...http://books.google.com/books/about/Geometric_Algebra_for_Computer_Science_R.html?id=-1-zRTeCXwgC&utm_source=gb-gplus-shareGeometric Algebra for Computer Science (Revised Edition)
