Session Name Fundamentals of Grassmann Algebra
Speaker(s) Eric Lengyel
Company Name(s) Terathon Software LLC
Track / Format Programming

This session provides a thorough introduction to the basic geometric properties of the wedge product and multivectors as they would be used in game development. Particular focus is given to the geometric manipulation of points, lines, and planes in generalized homogeneous coordinates. It will also explain how seemingly quirky behaviors in everyday graphics programming, such as the transformation of a normal vector by the inverse transpose of a matrix, arise naturally when viewed from a larger algebraic context.
