Hello genius!  
I’m a beginner and I need your help.  
How can I find the distance between two 3D objects in a 3D space?

Hi,

you can also use [dist](https://processing.org/reference/dist_.html) or [PVector.dist](https://processing.org/reference/PVector_dist_.html) like in 2D for 3D coordinates.

Cheers

Hello,

In addition to the helper functions it is good to know the math under the hood:

> **[Distance between 3D Points](https://www.engineeringtoolbox.com/distance-relationship-between-two-points-d_1854.html)**
>
> Distance between two points in a three dimension x, y and z coordinate system - online calculator.

Processing source for _dist()_ function:  
[https://github.com/processing/processing4/blob/master/core/src/processing/core/PApplet.java#L4750](https://github.com/processing/processing4/blob/master/core/src/processing/core/PApplet.java#L4750)

Give it a moment to open and find the line! Slow here for me in Google Chrome.

The PVector one is in here:
