Experimenting with the Geometry Proximity node

In the following exercise, we’ll show you a really cool example of what you can do using Geometry Proximity nodes. We will be creating a heat map based on where the geometry resides in our scene.

1. To get started, let’s add a plane into our Viewport and subdivide it a bunch, as seen in Figure 13.27:

Figure 13.27: Subdivided plane

2. Once you have completed this step, let’s go out of Edit Mode and add a Suzanne primitive to your Viewport. We will use this object to experiment with.
3. Next up, let’s go to the Geometry Node editor and add a new node tree to our plane.
4. Let’s start this node tree by adding an Object Info node and referencing our Suzanne object. Make sure to set the transformation mode to Relative. This will allow us to move our Suzanne object and have the results update correctly.
