Iterate pcfilter with a for loop ?

[dpap]

Hi  everybody and happy new year !!!

 

My first problem in Houdini this year has to do with for loops.

 

How can I repeat/iterate the smoothing from pcfilter on an attribute ?

 

The obvious is the FOREACH sop but can't I just use a for loop in the point wrange or in vops?

 

I thought that the last solution would be much faster so I tried to put the pcfilter function in a loop but I guess I am doing somehting wrong?

 

Can anyone shed some light?

I guess you can't

since pcopen is always opening geometry from @OpInput1 it will always filter points from that geo and not points from previous iteration

so no matter how many times your for loop will run it will always look the same

so you probably have to use foreach SOP

 

and that implicit cast error is just because you are using ch("numopoi") in pcopen and houdini doesn't know exactly which type of ch() to use (even though you would guess it should use int since numopoi parm is integer)

so you need to explicitly cast it to int by using int(ch("numopoi"))

You can also use the chi function to return an int I think.
