Introduction

The graphics system has changed significantly with MuPAD® 3.0. The renderers both for 2D as well as for 3D plots are newly implemented allowing for many new and enhanced features such as animations, improved interactive manipulation etc. The number of plot attributes has increased ever so much, now allowing to fine-tune almost any aspect of a picture. The MuPAD renderer now utilizes OpenGL®  drivers producing 3D plot output of high quality.

To aid the user in fine-tuning a plot, an object browser is provided with the MuPAD graphics tool. It allows to inspect and analyze the tree structure of graphical scenes interactively, giving easy access to all parts of the plot by a mouse-click. After selecting an object, all plot attributes such as color, line width, annotations etc. associated with the object become visible. One may select the attributes with the mouse and change their values interactively (see section Viewer, Browser, and Inspector: Interactive Manipulation). Thus, almost any detail of a plot generated by a MuPAD call can be changed interactively making it possible to fine-tune both the contents as well as the looks by visual inspection.

The new features of the renderers are fully supported by the plot library. It provides a list of graphical primitives such as points, lines, polygons etc. that one may use to build up highly complex graphical scenes. The primitives also include graphical objects that are not at all “primitive,” but come along with advanced algorithms and much built-in intelligence. Examples are function graphs in 2D and 3D (with automatic clipping for singular functions), implicit plots in 2D and 3D, vector field plots in 2D and 3D, graphical solutions of ordinary differential equations in 2D and 3D etc.

This document gives an introduction to the new graphics system. It provides an overview and explains the basic concepts and ideas. It contains a concise reference via help pages for all graphical primitives and attributes. Many examples are provided.
