Groups to attribute conversion

[Malcolm Zaloon]

Hi!

 

How to transform point Groups to attributes?

 

i need transform point grouping based on normal angle, and transform it to an attribute so i can "blur" the attribute...

 

 

I can "fill" the group with attribute, it´s an idea, but there is another "more direct" way to just convert it?

any ideas?

 

 

thanks in advance.

Hi Malcolm,

 

I think the better way is to put an attribut create after your group. Then you set the "group" with your group name and set the value to 1.

Now you have an attribut with a value of 1 only for points in the group.

 

Hope it will help.

Not sure I got your question correctly but if you want to "blur" an attribute there is this useful tip from attribTransfer's doc : http://www.sidefx.com/docs/houdini13.0/nodes/sop/attribtransfer

 

 

 

Tip

If you wire the same geometry into both inputs of this node, you can use it to “blur” attributes across surfaces.

Yeah, this is the "fill" method i mentioned.. i tested, works very well anyway.

 

the question now is a fast attribute blur, because blur node is very slow when i need much blur...

any idea to fast blur attribute?

 

thanks Paul!

Hey Malcolm,

 

You can try the in vop pointcloud open + pointcloud filter which will average the attributes base on there neighboor.
