Pmad.Geometry

NuGet

Geometry shapes and primitives toolkit (2D).

This project aim to provide optimized versions of 2D geometry arithmetic primitives used by GameRealisticMap and MapToolkit.

Those primitives are performance critical for the two related projects (data processing requires usually many hours, even little improvements can save a lot of time).

Current toolkit is an experimentation around Vector128, Vector2 and plain scalar implementations. It makes heavy use of generics and text templating to test multiple implementations of 2D vectors and shapes. It's intend to measure their relative performances on modern hardware.

API might change in future releases.

It includes a fork of Clipper2 from Angus Johnson.

Implementations

Vector Description Note
Vector2I Two scalar int Some operations are optimised with Vector128
Vector2F Vector2 wrapper
Vector2L Vector128 with long
Vector2D Vector128 with double
