Hi !

I want to create some geometry, that is recursive.
But I am stuck.
something in the lines of

func (x,y,z,size,level,Obj)
for i=0 to 2
for j=0 to 2
for k=0 to 2
if (i!=1) or (j!=1) or (k!=1) then
if level>0 then
func (x+i*size,y+j*size,z+k*size,size/3,level-1,Obj)
else Obj(x+i*size,y+j*size,z+k*size,size)
next k
next j
next i
removeDoublePoints()
removeDoubleEdges()
removeDoubleFaces()
SetPivot()
endfunc

Using Geometry nodes should be inappropriate, because I guess, I am not allowed to feedback a nodes output…

What did I miss… ??

TIA !

There is a Feedback SOP in the protoinstall.

THX Wolfwood,

but you're just confuzing me. I'm still confuzed. Only “Feedback” node found so far is a CHOP… (me still noob!!) and the 9.5 online help did not show anything related to protoinstall.

I thought I could use some Hscript/Python, to implement that function.

Thanks for your suggestion anyway!

Offhand, I don't think there should be any issues in creating a Python SOP for recursion if you want to go that route.

Also, look at the ForEach SOP

but you're just confuzing me. I'm still confuzed. Only “Feednack” node found so far is a CHOP… (me still noob!!) and the 9.5 online help did not show anything related to protoinstall.

You need to run the command line tool, proto_install. Select Windows->Shell from the main menu. Then do:

source $H/houdini_setup
proto_install


SOP_Feedback.inst should be somewhere in the list; enter the number & select “2) Install in …/houdini9.7”. Restart Houdini, and it should appear in the SOP list.

Proto-installed OPs are operators that are not yet tested for full production use, so use them with care.
