Objective:

Learn how to mirror an Implicit Body

Procedure:

The steps may be involved the first time around, but as always, we can create a Custom Block with them to easily repeat the process when we need it.

1. Start with the Implicit Body you want to mirror and create a Plane (or implicit body) to use as your mirror. Make both of these blocks Variables and name them.

2. Create a simple vector field. This will be used to create the reflected mirror field. 

• • Add a Vector Field from Components block 
  • Set the X, Y, Z values to X, Y, Z

3. Create the Reflected Field

• • Add a Multiply block and multiply the scalar field of the Mirror by -2

• • Add a Vector Field from Gradient block using the Mirror as the Scalar Field

• • Multiply both of the previous steps together

• • Add the result of this to the Simple Vector from Step 2. to create the Reflected Vector

4. Remap the Field to Mirror the Object

• Add a Remap Field block
• For Scalar Field input use the Shape from Step 1 (the object to be mirrored)
• Use the Properties from the Reflected block, use X, Y, Z for each input

And that’s it! You’ve successfully mirrored your object. 

As an added bonus with this Custom Block, you can use any Implicit Body or Plane as the Mirror Plane. Try mirroring your object with a sphere.
