    Looking to build a 3D grid similar to the image below taken from Google Blocks.

    Seems like it consists of these main components:

    1. A set of spheres that can go transparent.
    2. A stencil that follows the controller's location.
    3. When stencil overlaps with spheres, they show up, otherwise, alpha fades to zero.
    Any advise on how to approach building this?
