boundingbox of group

[EdwardBrian]

Hi,

I d like to set the pivot of a transform node to the min ore max value of a defined sourcegroup... $XMIN a.s.o. just give me the bounding information of the whole iput geo ...

following the houdinihelp in need something like "The X extents of the bounding box of the input GROUP" and not the INPUT itself

Thx a lot !

greets

Lucas

You could try something with Python

geo = hou.pwd().geometry()
group_points = geo.findPointGroup("group1").points()

x=[]
for i in group_points:
    x.append(i.position()[0])

min_x = min(x)

Python might get somewhat slow for large point groups.

You can also branch off into a DeleteSOP and grep the values from there ...

I'd say the easiest way is to just use a Bound SOP on your group and then use a centroid() expression to get whatever values you want from it. See attached.
