Have VEX Control Objects Using Distance And Height

The idea behind Houdini’s VEX is that you don’t really have to be a programmer to work with a low lever programming language. In reality, that is only partly true. You still have to understand some concepts, that for us artists, might be hard to grasp. Setting something up where VEX control over objects in the scene requires some underlying understanding of the functions involved.

This lesson takes a simple practical example to cover a few more Vex functions

You can get your feet wet with VEX thanks to Rohan Dalvi’s Introduction to VEX, using the “No Programming required” method. With it, Rohan dove into important elements for creating VEX code that included syntax, values, Wrangles, and some practical examples.

A new tutorial is being labeled as an extension to the first intro to VEX. It shows how you can employ Houdini VEX to create a scene where flowers will react to the sun in the scene. As the sun moves up farther from the horizon, the flowers will open up and follow the sun’s position. This requires a system that will effectively “look at” the sun, and this is where VEX control comes in.

This is a nice practical example that will cover more VEX functions than the first introduction. Rohan walks through create a “look at” using VEX control over objects using distance and height values passed along from another source. Nice!
