7: Elevating Terrain with Proximity-Based Positioning
I took my proximity experiments further by adjusting the terrain itself based on the proximity to certain objects.
Process
Using the Set Position node, I directed point information into a Geometry Proximity node. I then connected the Distance output to a Float Curve node to modify the Z-axis position.
This setup allowed the ground to rise as it approached the trees, giving the illusion of roots or mounds beneath them. Inverting the Float Curve was key to achieving this effect.
Nodes Used and Their Functions
- Set Position: Changes the position of points in the geometry.
- Geometry Proximity: Provides distance data between geometries.
- Float Curve: Adjusts values to control the effect intensity.
