Essential Mathematics for Computational Design Essential Mathematics for Computational Design by Robert McNeel Associates is licensed under a Creative Commons Attribution-Share Alike 3.0 United States License. ii Essential Mathematics for Computational Design Preface Essential Mathematics for Computational Design introduces design professionals to foundation mathematical concepts that are necessary for effective development of computational methods for 3D modeling and computer graphics. This is not meant to be a complete and comprehensive resource, but rather an overview of the basic and most commonly used concepts. This book is directed towards designers who have little or no background in the ® subject. It assumes that readers have good knowledge of Rhinoceros (Rhino), ® NURBS modeling for Windows, and Grasshopper (GH), the visual scripting environment for Rhino. Both are used as tools to explain various concepts. For more information, go to and . This book has three parts. The first discusses vector math including vector representation, vector operation, and line and plane equations. The second part reviews matrix operations and transformations. The third part includes a general review of parametric curves with special focus on NURBS curves and the concepts of continuity and curvature. The material in this book is based partly on a workshop I held at the University of Texas at Arlington for the Tex-Fab event February, 2010. Rajaa Issa Rhino Development Robert McNeel Associates
