pscale by height

[dubCUT]

Hello

how can i rescale "pscale" by "P.y" when i transform the whole thing in the end?

copy stamp?

As i understand "pscale" must be set before "copy to points".

i know i could move up the transform node, but for the sake of learning something new, i don't :-)

thank you

@dubCUT I have this that I use For patterns with Color and Chops ...I think that its not Right  ...I Have only this..
+ you have endless examples here
https://github.com/qLab/qLib

Try Using Different Math Function in Help Panel .

vector bmin,bmax;
getbbox(0,bmin,bmax);
f@pscale = fit(@P.y,bmin.y,bmax.y,0.1,1);

you don't need Chops or any HDAs for that

Don't listen to anyone you need everything

[jfaulkner]

f@pscale = relbbox(0, @P).y;

Would be the simplest approach I reckon.

thank you very much for your inputs!

@Librarian

guess i need to have a look at qlib. thanks for the setup, i need some time to fully understand this, but it looks like sorting id by size. nice!

i don't understand where to put that bbox wrangle... as i rotate the grid at the end of the node chain and pscale must be written before copy to points.

@dubCUT Here is a quick example using similar approaches to bunker's and (kinda) jfaulkner's methods above except that I went for a slightly less procedural approach in favor of more "direct" control by making all the values in sliders for easy control.

And for easy readability for future readers, here is the code I used if you don't want to download a hipfile:

f@pscale = fit(v@P.y, chf('Min_Height'), chf('Max_Height'), chf('Min_scale'), chf('Max_Scale'));

In the wrangle you have shown will work

thank you all!

that's very kind. (and a lot to digest, as always :-) )
