Attributes, Variables & Parameters

You’ve learned a tonne of crucial theory so far. We’ll teach you more here, but that’s not all. Let’s put the theory to work, teaching you how to apply your new skills to real projects. We’ll build a procedural system together, complete with project files.

By the end of this course, you’ll have a deep understanding of:

• The difference between attributes and variables
• What the deal is with local and global variables
• How to access and reference the bounding box with parameter expressions
• How to use the normal and up attributes for precise control of orientation
• Resampling curves with accuracy using arc and chord length measurement methods
• Using the ray node to project geometry
• Customising tools with spare parameters
