XSI Illuminated: Expressions
In this lesson, you will learn:
¨ How to automate simple tasks with expressions
¨ How to think creatively with math and formulas.
¨ How to simply do special effects that would otherwise be impossible


Introduction
XSI was built from the ground up to be extensible. WhatÕs even more unusual is that XSI can be extended with standard scripting languages like VBScript and Jscript, as well as with a C or C++ development kit. Making a program open and extensible means that youÕll always be able to do what you need to do Ð even if you have to write a bit of code to get it done. Fortunately, XSI has a continuum of extensibility, starting with the easy to use and simple expressions, followed by the still easy to use but slightly more complicated Scripting functionality, and ending at the full blown computer science of the SDK (Software Development Kit). This section addresses the first one Ð the easy one, expressions.
