Connecting points with edges based on attributes

[sleg]

Hi guys.

I have a set of 'points'. Each point has a unique id.

Now, I'm getting these point out of another package which also gives me a parent ID attribute to define a sort of 'hierarchy'.

So I would have something like

point 1 has an id of 1 and a parent id of -1 (none)

point 2 has an id of 2 and a parent id of 1 (1 is his parent)

point 3 has an id of 3 and a parent id of 1 also

point 4 has an id of 4 and a parent id of 2 (his a child of point 2)

ect...

So basically what I want to do is trace an edge between every parent and its children... I've tried putting some variables in the 'add SOP' but it seems that the only variable that seems to give me anything is $N. But that's no use to me.

Any ideas?

Can you share the scene or an example?

Sure I've baked it all into a null because the stuff above is full of dependencies.

So all it is is this node with the attributes 'id' and 'parentId'.

EDIT: I basically want to start by being able to connect all points with, for example, a parentId of 3 to the point that has a geomGroupId of 3.

The id attribute seems to be missing in the file. I've got a working version with $PT.

Is this something you are looking for?
