Look, ma, no matrices (enkimute.github.io)

Article summary

The article discusses the use of Geometric Algebra (GA) in computer graphics, specifically the replacement of matrices with GA's motor manifold. The author presents a project that aims to integrate GA into a 3D engine, highlighting the benefits of GA in terms of computational efficiency and geometric intuition. The article also provides examples of GA operations, such as the geometric product and sandwich product, and their implementation in code. The goal is to demonstrate the potential of GA in computer graphics and encourage further exploration of its applications.

What commenters say

• Geometric Algebra is a more intuitive and efficient approach to computer graphics than traditional matrix-based methods.
• The use of GA can simplify complex geometric operations and provide a more unified framework for graphics programming.
• The learning curve for GA can be steep, but it provides a deeper understanding of geometric concepts and their relationships.
• Traditional matrix-based methods are still widely used and well-understood, and may be sufficient for many graphics applications.
• GA provides a more consistent and capable approach to interpolating rotations and other geometric transformations.
• The choice between GA and traditional methods depends on the specific needs and goals of the project, as well as the expertise and preferences of the developers.
