Sunless - Architecture Core
Released
Make scene components with a handy little editor tool (ALPHA)
Editor/Geometry/ArchFrame.cs
A simple immutable value type that represents a local coordinate frame for an arch or path segment in the editor. It stores position, basis vectors (Along, Across, Up), and some scalar properties, and provides convenience accessors to compute side positions, a 2D flat position, and yaw in degrees.
