One of the things I do whenever I have some downtime is explore or learn a new technique and then save that out so I may use it in the future. As I continue to get deeper into Houdini I wanted to understand how to map colours to heights. For this I mapped the y value using a PointVop and a colour ramp. Then I created a group using an expression to create a series of points from half way up the terrain to the top and mapped that height to govern the size of tiny spheres. All this adds to my learnings to better understand the tools I use.
