I would like to build a fuse patch, where the position of a sphere follows the height of a noise topography. Something along these lines:
(This is obviously not correct because the elevation of the sphere is not in sync with the height at the xy position of the topography. )
I came up with this solution:
The sphere indeed changes in height, but not the way i want it. I could use the node “nearest point on sdf” but I found if expensive and it also changes the xy values.
Does anybody can give me a hint how to fix that?
