How to "scale" a group of objects around a point?

[Arwimiles]

Hello! I’m trying to make a hologram system where all actors of a given class are recreated in a miniature view. What I want to do is “scale” those objects to the position of the hologram project, resizing them while moving them to the appropriate space.

Eventually I want to be able to orbit, scale, and pan the hologram projection as well, but at first I’m just concerned with how I mess with the transforms to get them to be positioned in such a way. Here’s a clip in Blender showing what I want to be able to to do:

Would someone happen to know what series of math nodes I need to achieve something like this? Thanks for any help!

Well I figured that out quickly! I just needed to lerp the two locations by a variable that I would then use 1 minus of to set the scale.

I’m still not sure how to do the orbiting around the central point, but this covers scaling, and translation should be easy to add.
