I am trying to store my primitive group name in a variable in VEX and I would like to do it in a procedural way something like:

s@name = @group_*;

Off course this doesn't work, any tips?

Thanks.

You can use Name SOP for this, but if you need more flexible way here is how to get all point groups that point belongs to

So just change it for prim groups

Thanks dude!
I`ll try that!

I am surprised to see how old this topic is and there is still no function in VEX that could achieve it. Something like isgroup() where you feed a string and it returns 1 if it that group exists and the point/prim/vertex is in the group, 0 if it exists but it is not in the group and -1 if it doesn't exist.

Is there something I am missing on why this function is not a good idea? Or is there already a function that can achieve something similar?

Thanks!

It is exactly what these functions do, except for the -1 for group existance, it will be 0 in this case :

inprimgroup() [www.sidefx.com]
inpointgroup() [www.sidefx.com]
invertexgroup() [www.sidefx.com]

You can use the detail intrinsics for the groups.


Same for pointgroups, edgegroups and vertexgroups.

both of which are already mentioned in above links so I'm not sure what this missing VEX question is exactly about

I think I wasn't too clear about what I was looking for and for some reason I got mixed up the link in your first reply with a different post about the same topic that gave a python solution.

You can use the detail intrinsics for the groups.

i@found = 0;
string groups = detailintrinsic ( 0, "primgroups" );
if ( find ( groups, "group1" ) )
    i@found = 1;

Same for pointgroups, edgegroups and vertexgroups.

This was what I was looking for and indeed it is also explained in the link you provided.

Thanks and sorry for the missunderstanding!
