first point of the primitive

[mic]

hello!

please help me to query the number of first (or any else) point of the primitive.

what i want:

i must create an expression like:

point ("../node1", ##[here must be first, second or third point of the primitive, which number i calculated before using 'xyzdist']##, 'some_attribute', 0)

so, i need the list of points which form my primitive.. how can i get it? thank you!

You could use a PythonSOP, perhaps?

thank you, Jason, i'll try!

[mic]

the python SOP didn't help me..

but i've found another solution.

if anyone is interested, please look the example scene.

Fastest way to find first point of each primitive:

Add "primitive SOP"

Switch to Attribute tab

Add Alpha

Replace $CA with $PT

After doing this primitive`s alpha attribute will contain first point number.
