I am wondering of there is a way to use a height field to position objects.
For example, I would like to place glows slighty above an undulating hf.
Here is a
visual representation:
O
___|____ O O
___________
|__|___ O __________|________|
|___|_____|
The circles are where the glows would appear. I would like to do something
like use the hf height to modify the glow height. Maybe <somex,
hf+0.25,somez>
Is this possible?
