vol105: CAVE: Channels, Attributes, Variables and Expressions in Houdini.

(Previously called "Math for Visual Effects")

Purchase the class

This class is for the user already comfortable with the Houdini interface and procedural method.

I go into great detail about "CAVE," Channels (parameters,) Attributes, Variables, and Expression, and how these are used to connect the different editor "contexts" of Houdini, and how they are used to create some amazing effects.

These are the parts of the software which are not as visible at the GUI interface level.

But they are as important as the nervous system is to a living creature.

Modifying numbers in Houdini with math function is one of the powerful tools in this software.

This class is about:

• Where to find the numbers

• How to change them with various math function

• Where to push those modified numbers to make them useful.

Most of the Houdini effects artists and technical directors said they didn't care much about math when they were in high school or university.

It was only after learning a 3D program or watching what others were doing with math, that they learned that some really cool effects and tricks can be created by knowing a little more about math.

In this course I hope to show you what can be done with numbers and strings to make some cool effects.

There are many example Houdini .hip files, and many video lectures.

Students are expected to make many small learning projects to test and explore the tools.
