Geometric Algebra Computing in Engineering and Computer Science: A Comprehensive Exploration
Geometric algebra (GA) is a mathematical system that combines the power of vector calculus, matrix algebra, and Grassmann algebra. It provides a unified framework for representing and manipulating geometric objects and their relationships in a consistent and efficient manner. GA has found widespread applications in various fields of engineering and computer science, including robotics, computer graphics, machine learning, and more.
GA is based on the concept of a geometric product, which combines two vectors to produce a new vector, bivector, or pseudoscalar. The geometric product is defined by the following rules:
- Vector product:
a ∧ b = a × b
(vector cross product) - Scalar product:
a ⋅ b = a · b
(scalar dot product) - Bivector product:
a ∧ b = a⊗b - b⊗a
(exterior product)
These operations allow for the concise representation of geometric transformations and relationships, such as rotations, translations, and projections. GA also introduces the concept of multivectors, which are objects that can represent a combination of vectors, bivectors, and pseudoscalars.
