Generalize cross-ratios in n-dimensional Plane-Based Geometric Algebra
Enzo Harquin, Stephane Breuils, Pascal Monasse +2
We develop a complete theory of projective cross-ratios in n-dimensional Plane-Based Geometric Algebra (PGA), R(n,0,1), covering geometric objects of every grade: finite and ideal…

Efficient representation and manipulation of quadratic surfaces using Geometric Algebras
Stéphane Breuils, Vincent Nozick, Laurent Fuchs +1
Quadratic surfaces gain more and more attention among the Geometric Algebra community and some frameworks were proposed in order to represent, transform, and intersect these quadra…
