Math.NET Spatial, providing methods and algorithms for geometry computations in science, engineering and every day use. Supports .Net Framework 4.6.1 or higher and .Net Standard 2.0 or higher on Windows, Linux and Mac.
Initially developed to provide an easy way to manage Geometry objects with serialization and deserialization functions and transformation functions from/to GeoJson, it also supports GML, georss and Well Known Text (WKT)
GeometRi is a simple and lightweight 3D geometry library for .Net. Its main purpose is manipulations with basic geometrical primitives, such as point, line, plane, segment in 3D space: translation and rotation operations, distance calculation, intersections, orthogonal projections of one object into...
The Google S2 Geometry Library is a spherical geometry library, very useful for manipulating regions on the sphere (commonly on Earth) and indexing geographic data.
This version targets NET Standard 1.0
xBIM Geometry is an optional component of the XBIM Toolkit
providing support for generation of 3D Geometry from Ifc4 and Ifc2x3 representations.
Use this package to update your XBim IModels to contain geometry that can be visualised in 3D.
Currently supports IFC2x2, IFC2x3, IFC4 Addendum 2...
