This package provides a 2D scene graph api based on the rendering capabilities of java.awt.Graphics2D.

tool box for the facetedge package

The discretegroup package is a metric-neutral framework for working with the fundamental groups of 2- and 3-dimensional euclidean, hyperbolic, and spherical orbifolds and manifolds, with particular focus on a visualization link to jReality.

The jgimmick package provides useful swing gadgets: a jog wheel and a timer control panel.

The mathExpr library provides classes to parse and evaluate mathematical expressions.

The projgeom package is a metric-neutral framework for working with Pluecker line geometry and Lie sphere geometry in their natural embeddings as Cayley-Klein geometries in projective 5-space.

jPETScTao is the name for a Java project, that tries to make a part of the functionality of two numeric libraries PETSc and Tao accessible for Java programs. It utilizes the JNI to achieve that. See

Lots of interfaces that describe different domains and functions.

Provides the classes for a facet edge data structure.

mfc provides mathematical foundation classes, e.g., complex numbers, polynomials, 2x2-matrices, fractional linear transformations, quaternions.

Provides the classes for a half-edge data structure.

The ellipticFunctions package provides a library for elliptic functions. Some of the most famous mathematicions of the 18th-century, like Abel, Gauss, Jacobi, or Weierstrass, contributed to this subject and opend a complete new field in mathematics.

The java2dx package extends java2d by connecting java2d functionality with that of other jTEM projects (modelling, numericalMethods, jrworkspace, beans)

This package implements numerical methods and algorithms for the evaluation of certain automorphic functions and forms in the context of Schottky uniformization.
