Now, let’s return to stretching and shifting by multiplying the axes by factors. However, we will now perform these operations in a spatially varying manner. Let’s look at a diamond TPMS geometry:

​
Variably Stretching

Using a Plane from Normal, let’s ramp from 0mm to 10mm and create a field that goes from 2 to 1. View the resulting field by pressing ‘F’.
Now, let’s multiply the x-axis by this resulting field. 
This remap is going to stretch/pull out/extend this geometry in the x-axis.
You can also play around with the spreading factors to see how they affect the output. We can do a similar stretch field in the y-axis, and it will result in a 3D pyramid structure like this:

​
Variably Shifting

Similar to stretching using the Divide block, you can shift using the Add or Subtract blocks in a spatially varying way. Here, we shift on both the x-axis and y-axis at once.
