Sorting and Remapping Attributes

[tfreitag]

Hey,

I have the following issue. I have an ID attribtues wich looks following: 0,0,0,1,1,344,344,344,344,999,999

Now I want  increase by one, like so: 0,0,0,1,1,1,2,2,2,3,3,3

I tried a lot i.e.  partition sop, loopings with vex...but no success. Does anyone have an idea?

 

thanks. tom

perfect!! thats what I want. i did the vex code in point mode...so detail mode and the loop over you point is way to go. thanks!

I had a go with python..and for good measure, I sabotaged the nicely ordered ID sequence by randomizing the order 0,0,0,1,1,344,344,344,344,999,999.

beside needing an extra partition node, the python code is actually quite succinct.
 

node = hou.pwd()
geo = node.geometry()

i = 0
for group in geo.pointGroups(): # loop for each group
    for point in group.points():
        point.setAttribValue("id",i) # reset id to sequential counter
    i += 1

thanks for sharing the python approach. good to have a alternative solution.
