Shape Generator - Getting started with Blender Nodes Part 6
Jump on the Discord server for more procedural goodness: / discord
This time we're creating a node group that can output any regular polygon as either a solid shape or an outline!
Less complex than last week's tutorial - I really wanted to illustrate Dot Product as it's so powerful. We're also reviewing some of the trigonometry we touched in the Radial Arrays in part 3!

03:30 Creating our vectors
05:45 Using the Dot Product
06:57 Drawing an outline
07:41 Making the group node
09:40 Adding rotation
