MuPAD ... Graphics


MuPAD has an interactive graphic interface (called vcam) to create and manipulate 2D and 3D scenes. Graphics can be saved as GIF-images, Postscript-images or in special MuPAD formats. We're also working on a filmtool to animate them. The following examples were made with vcam.

Graphical primitives

Graphics can be build up on graphical primitives like points, polygons and colour-filled triangles by putting them in a list. This especially allows turtle graphics and other plots of discret objects.

2D-Graphics

2D graphical scenes may consist of serveral 2D-objects of different colours, line styles and with different titles. Colours may be defined flat, corresponding to the height (y-axis) of an object or by a user-defined colour-function.

3D-Graphics

3D graphical scenes may consist of serveral 3D-objects of different colours, line and surface styles and with different titles. Colours may be defined flat, corresponding to the hight (y-axis) of an object or by a user-defined colour-function. Surfaces may be displayed as colour patches or transparent. Also wireframe as well as hiddenline models can be plotted.

Animations

The following animations are calculated with MuPAD and given as Quicktime movies (with the suffix .mov). To watch them, a Quicktime movie player - e.g. like the public domain programs xanim on Unix systems and MoviePlayer or sparkle on Apple Macintosh - is needed. Maybe you also have to configure your WWW client (netscape, mosaic, ...) and tell it how to launch these applications.

On Unix systems, if xanim is installed on your machine, add the following lines to your private ~/.mailcap file. No space must be left after the symbols '\':

               video/quicktime; \
                      xanim %s; \
                      test=test "$DISPLAY" 
On Apple Macintosh (netscape) use the Preference entry of the Options menu to configure how to handle Quicktime movies.

Try to reload this configuration file within your WWW client. If this is not possible, you have to restart it.

After that, click here to start the first animation (800Kb). If your WWW client cannot handle gizp-compressed files then click here to get the uncompressed version (2.5Mb).
