MongoDB Atlas runs apps anywhere
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
This is an application made for educational purposes. It demonstrates some basic algorithms of computationalgeometry in 2D space. You can create, edit and delete points and vectors and then choose them as the input for algorithms selectable from the menu. Import and export from a to XML files is also possible.
Many thanks to GeoSoft for providing open-source library G which was used for 2D graphics. You can find it here: http://geosoft.no/graphics/index.html
Geom4J is a computationalgeometry library for Java. It contains implementation of the most important computationalgeometry data structures and algorithms coded in pure Java, designed for ease of use and optimized for performance.
CGTutorial is a computationalgeometry tutorial written in Java. It implements various CG algorithms and animates some of them. A library of CG methods and data structures is provided, in the form of Java packages.
This project seeks to develop tools for investigations into computational aspects of algebraic geometry over free groups. In particular, we are developing software implementations based on the theoretical work G. S. Makanin, A. Razborov, and others.
