Softimage support’s Stephen Blair show how to use Vector Subtraction to Put a Point on a Curve in Softimage ICE demonstrating the importance of vector math such as subtraction.
Stephen Blair writes: When you’re moving points around with ICE, it’s important to understand the basics of vector math, such as vector subtraction. It’ll help you understand and visualize (in your head) what you’re really doing when you plug together nodes in an ICE.
To demonstrate, I show how to use vector subtraction to move a point on to a circle.
