In lesson #1, we use the Vizzie subsystem to allow people to quickly become familiar with the basic functionality of a visual programming language, and to learn some of the functionality of the Max environment. For this to be useful, a current version of Max - along with the Vizzie components (automatically installed with Max) - should be installed on the user's systems.

Introduction to Vizzie

Max takes a different approach to programming: it provides a visual, rather than textual, view of the code-creating process. There are some advantages to vusion programming:

  • It engages visual-spacial interaction with the code.
  • It combines the user-interface with the program logic.
  • Sub-programs are easily - and visibly - integrated in new programs.
  • It is often more approachable for non-programmers.

The basic workflow of Max programming (and other visual programming tools) is:

  1. Create objects
  2. Connect these objects to other objects
  3. Repeat!

Visual programming works well with an iterative development process, where you create a small working section of code, then add new pieces as required. An important part of this is to create reusable subsystems; for example, it is typical to create a working Microsoft Kinect subsystem, then reuse it every time you need to work with a Kinect. These subsystems are built using Max itself, and are easily made available for future projects.

In this set of lessons, we use a subsystem called "Vizzie" (automatically installed with Max) that is used to manipulate visuals (movies, images and live video). This system is meant to provide an easy introduction to visual programming, and to provide a "fun" way to get started. There are some limits to the Vizzie subsystem:

  • You are limited to the output video resolution (maximum of 640x480).
  • It has limited means for saving state and reloading content.
  • It is a little garish looking - but this is done on purpose, since it makes it easy for an instructor to quickly identify a program's logic.

Some people wonder if working with Vizzie is actually working with Max. We consider it to be so, since it works within the Max environment, can interface with lower-level Max code, it uses standard Max messaging, and the user and programming interfaces are the same.
