vol105: CAVE: Channels, Attributes, Variables and Expressions in Houdini.
(Previously called "Math for Visual Effects")
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.
Watch a Sample Lecture from vol100 on using the Wedge ROP and creating a custom wedge method.
Chapter A: Where Numbers are Found
Chapter B: Modify Points with Basic Math Functions
Chapter C: Modify Primitives with Basic Math Functions
Chapter D: Animation: Moving Numbers Over Time
Chapter E: Components of the .geo, .obj, .idf and .rib Geometry Formats
Chapter F: Putting the Math to Work
Chapter G: Expression Tricks
Chapter H: Library of Expressions
Chapter I: CHOPs, Channel Operators
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.
