The jTEM project beans provides the means to auto generate a GUI to inspect objects that conform to the JavaBeans™ specification.

The basic linear algebra system is a package that provides classes for integer, real, and complex matrices and vectors; which forward the actual calculations to the corresponding methods of the jTEM packages mfc and numericalMethods.

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 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.

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

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

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

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
