Accessing Particle Clusters under a Particle Cloud

Accessing Particle Clusters under a Particle Cloud

1. Start by getting a pointer to the particle cloud.

CreateParticleCloud( "", "Grid" );
var pcloud = ActiveSceneRoot.FindChild( "", siCloudPrimType );

2. Enumerate over the children of the ParticleCloudPrimitive looking for the cluster container (of type cls):

var cprim = pcloud.ActivePrimitive;
var clsters;
var e = new Enumerator( cprim.NestedObjects );
for ( ; !e.atEnd(); e.moveNext() ) {
   if ( e.item().Type == "cls" ) {
       clsters = e.item();
       break;
   }
}

3. Now enumerate over the children of the cluster container looking for individual clusters. Because particle clouds contain only points, the type to look for is pnt:

var cls;
e = new Enumerator( clsters.NestedObjects );
for ( ; !e.atEnd(); e.moveNext() ) {
   if ( e.item().Type == "pnt" ) {
       cls = e.item();
       break;
   }
}
