Using Cross Product to add Intelligence
Procedural Hand Switching Intelligence using Cross Products in Houdini
Using the left and right hand detection that was taught in Cross Product Basic Concept #4 Part 1, I’m able to add some intelligent behavior to Erik. Erik will choose the hand that is closer to the ball to try to grab it. The hand switching is driven by some fancy Cross Product math.

Crowds, KineFX, & Cross Product All Combined Together!
Crowd SIM in Houdini Turning Heads Dynamically to what is placed on the Surrounding Environment in Houdini
I use all the things taught in the Cross Product series to make a Crowd of Rob agents walk down a street and react to the surrounding environment by turning Rob’s head towards some random points I scattered all over the shops on the street. Rob ends up window shopping all over the street! This is different from a simple LookAt Constraint because Rob stares multiple points on the shops, turning his head towards the closest to him. With a LookAt Constraint, you’re limited to looking at one point. This is the advantage of doing things manually.
Cross Product alignment to Text Bend Mesh in Houdini (Blender shaders)
I took some letters and turned it to mesh geometry and used a bend node to deform in an angle towards a floating ball. This was an example I used to demo one of the use cases of the Cross Product.
