Making use of geometry proximity
Geometry proximity is a function in the Geometry Nodes toolset that allows you to compute the distance of input geometry, such as vertices, edges, or faces.
There are two approaches to using geometry proximity:
- Manual calculation
- Using the Geometry Proximity node
You don’t have to make use of the node though, which does not work for every use case, and sometimes, you’ll have to calculate the geometry yourself.
You’ll only really be needing the manual calculation when you are working with empties, since they do not contain any geometry. Any other use case will probably make use of the Geometry Proximity node.
Let’s show you how to make use of each of these two methods.
Manual calculation
Let’s first start by explaining how the manual calculation of geometry proximity works. You’ll need this method mainly when working with non-geometry objects, such as cameras, empties, speakers...
