GRAPE (GRAphics Programming Environment) has been developed in Bonn at the Sonderforschungsbereich 256 for Nonlinear Partial Differential Equations since 1987. Since 1992, part of the software development is done at the Institut für Angewandte Mathematik der Universität Freiburg. At first aimed at the mathematicians in Bonn needing advanced computer graphics, now GRAPE is also being widely used in other scientific areas.

GRAPE is intended to serve as a general programming and viewing environment and it benefits from its interactive approach and its standard-C based yet object oriented structure.

There is a large amount of classes and methods provided. This covers different kinds of curves, surfaces, and volumes. A range of mathematical algorithms, especially from differential geometry and finite element theory, bridge the gap between numerics and graphics. There are advanced facilities for e. g. locally refining grids, reflecting objects, calculating particle traces, or deforming surfaces in flow fields. In addition GRAPE integrates the exploring of time-dependent problems by extending the object hierarchy to an animation concept, which is a particular feature of the program.

In 1994 GRAPE won the European Academic Software Award in the discipline of mathematics.
