Hello,
I'm stumped in setting up a simple Wedge to drive a group attribute for a Blast SOP. I'm trying to iteratively go through an existing group attribute that I have in my point cloud, delete-non selected groups and export for each group.
I cannot figure out what to type in the Wedge node in order to get a string value for my Blast SOP's group input parameter.
e.g. I have a point cloud with a group attribute for ea point of "classIndex0, classIndex1, classIndex2...etc"
I've tried setting up an integer attribute output (called "index") in the Wedge node to get the integer at the end.
Then in my Blast node I tried typing this to reassemble the group name -
`strcat("classIndex", itoa(@index))`
but it doesn't work, I get an error "Unable to evaluate expression".
--------------
Is there a better way to go about this?
Can Wedge output a string value with an incremental integer in the same string? This would be most straightforward way to me, but I can't figure out the syntax/expression/code to do this simple thing.
