GAViewer is a multi-purpose program for performing geometric algebra computations and visualizing geometric algebra. Some possible uses are:

• Visualizing geometric algebra output from other programs.
• Interactively performing GA computations and visualizing the outcome.
• Presenting lectures, slideshows, doing tutorials, demonstrations, with (interactive) geometric algebra animations.
• Rendering (hi-res) images of GA objects for use in papers.
• Debugging other programs using geometric algebra.

GAViewer has outgrown its original purpose. We initially created GAViewer as a small program for visualizing GABLE/Matlab output because we weren't satisfied with the Matlab graphics. Then we wanted to have a typesetting system for labels and support for slideshows. After some time the desire rose to add a console for interactive computations inside the viewer. After a console was added, we wanted to have functions and batches. Then dynamic statements were added. The latest additions include animations based an dynamic statements and scalar controls.
