I have a cube, that I want to copy to a grid, but have the cubes taller in the center, they would scale down as the got to the edge of the gird.

try to make a “city” like grouping of polys

any thoughts?

TIA

Reference in BoxSOP paremeter sizey (“Size”) in ty (“Center” in GUI). You can do this with drag and drop. Then divide it by 2. So in Center Y-axe field you should have something like: ch(“sizey”)/2.

Alternatively you could reposition pivot of a cube, for example with an expression like $YMIN which is valid in TransformSOP.


hope this helps,

read through this entire thread…then go back and download some of the sample files (some may not work 100% - H8 v H9)
you'll learn a ton about exactly what you're trying to do

you have lost me sorry.

would I use some random function in the copy SOP?

You could use the Paint sop and the Copy sop stamp function. See enclosed example.

Got it too work using the STAMP fuction, with scale and height rand(“../copy1 etc. looks good… but Im wondering is there away to have those box ”placed"
on a sphere… like buildings on the earth, I hope I can be understood.

thanks again for all this help!!!

You can simply replace the grid in Peter's example with a sphere.

Make sure you change the type to polygon (in the sphere sop)

in that file
put
ch(“sizez”)/2

in the “center z” parameter of the box1 SOP

One more thing them Im stopping for the night… my brain hurts.
If I still want to see the sphere that the boxes were copied to… like the ground they rest on, how would I do that.

Man this software is cool!

put down a merge sop, and connect both the output of the copy sop, and the sphere into it. set the display flag to the merge sop.

and just to be helpful…
the reason the sphere goes away is because you're only using it's points as a template to copy the boxes on to…by adding a merge SOP you can add the original sphere back into the geometry.
