A Homogeneous Model for Three-Dimensional Computer Graphics Based on the Clifford Algebra for ℝ 3. We show that main results of rational trigonometry (as developed by NJ Wildberger, "Divine Proportions", 2005) can be succinctly expressed using projective (aka homogeneous) geometric algebra (PGA). Geometric algebra is a very natural language for describing concepts in Euclidean geometry, but one aspect that can confuse people at first is that there is no single unique way to work.

He is particularly excited by his recent work on Projective Geometric Algebra (PGA), which he believes has a great role to play in bringing the benefits of GA to a wider audience. 4 Altmetric. 2D PGA Cheat Sheet C.Gunn, S.De Keninck. Parallel to the development of CGA, Charles Gunn proposed that an algebra that he denoted R 3;0;1 could have the rigid body motions precisely as its rotors, and that it should be the natural algebra for Euclidean geometry. 5.

Table 3: A sample of geometric constructions and formulas in the euclidean plane using PGA (assuming normalized arguments, all arguments euclidean unless otherwise stated). Rigid-Body Transforms Using Symbolic Infinitesimals. Clifford's geometric algebra (1878) provided a powerful tool for doing geometry in these spaces -- but he only described the non-euclidean case, which was only correctly worked out in this century. 3. The hope is that the student will find them to be stimulating and a reason to think deeply about the material.

Pages 353-369. Its useful structure had earlier been exposed by Selig [2] as the Cli ord algebra of points, lines and planes. Mr. Gunn then gave an overview of the steps remaining to obtain the geometric algebra of the Euclidean plane $\mathbf{E}^2$ from the geometric algebra of the euclidean vector space $\mathbb{R}^3$: Replace the standard exterior algebra based on the join operator $\vee$ with the dual exterior algebra based on the meet operator $\wedge$.
