novice - modify point inside SORT SOP

[art3mis]

Attached is a bare bones Point Effector using a SORT SOP. I want to be able to simply modify the xyz point inside the SORT SOP either manually or from the xyz coordinates of another geo (say a sphere) in my scene.

What is the best way to do this?

I played a lot with point sorting and it's really useful when it works as you want it too, but that's not always the case.

It might be a better solution to create a transitional point attribute, arrange it's values as you want, then use that attribute in a sort - that will give you a lot more control.

Sorting method will jitter on low point counts, I would avoid it. Here are four methods.

Thanks for the example and replies. Sometimes it feels like mastering Houdini must be like ascending Everest, except you never reach the summit!

I would propose it's more like a staircase - it's not really complicated per small piece, but there's just an endless amount of small pieces.  

But Houdini is amazingly consistent, so almost everything you learn will be applicable in many places.
