Can someone plz help me visualize this VEX code in Geometry VOPS? Trying to wrap my head around VOPS. Thank you.

vector pos = point(0,'P',@ptnum);
@v = pos-@P;
@v*=8;
//@P = pos;

I am not going to be able to answer that but I am just curious, why do you need a point function to fetch the P attribute from the first input (your geo number is zero, which is the first input) when you can simply use @P, I mean, the pos variable and @P should have the same value, no?

Connect a constant with the value ‘0’ to the v output.
