Read moreGeometry Library in C# — Operators
Saturday, April 4, 2026Third article in the series: we add +, -, * and / operators to our types so geometric code reads as naturally as mathematical formulas.
Read moreGeometry Library in C# — Creating a Point Type
Saturday, April 4, 2026First article in a series about building a geometry library in C#. We start with the most fundamental type: the point.
Read moreGeometry Library in C# — Transformations
Saturday, April 4, 2026Fifth article in the series: we implement geometric transformations using homogeneous matrices, then explore a lighter alternative with quaternions.
