RE: fastest way through script to get all parameters in a scene of certain value?

[Matt Lind]

The slowness is coming from using the Tag() command.  Try using the object 
model to cut out the middle man:

// Jscript
main();

function main()
{
                var oItems = ActiveSceneRoot.FindChildren2();

                LogMessage( oItems.Count );

                for ( var i = oItems.Count - 1; i >= 0; i--) {

                                var oItem       = oItems(i);
                                var oParameter  = oItem.Properties( 
"Visibility" ).Parameters( "viewvis" );
                                oParameter.Tags = siTagNone;
                }

                return;
}


If the parameters you are attempting to modify have a large degree of 
consistency in name and location, you can use some of Softimage's wildcards to 
find them faster:

var oParameters = XSIFactory.CreateActiveXObject( "XSI.Collection" );
oParameters.Unique = true;

                // Get viewvis and rendvis parameters of the visibility 
property on each X3DObject
oParameters.items = "*.visibility.{viewvis,rendvis}";

LogMessage( oParameters.Count );

If there is a large degree of consistency in the parameter fullname, you can 
apply values to the parameters en masse very efficiently:

                SetValue( "*.visibility.{viewvis,rendvis}", false );

better stated: certain parameter name, not value, apologies, running behind on 
sleep, words are challenging.

these are the three methods i've tried.
using tags is the fastest, but a little prohibitive, as you have to have 
anticipated needing to get a param quickly, so it must be tagged in advance.  
also, even with getting by tags, performance imo is pretty poor.

results on my machine from the code below:
# INFO : object count is 3618
# INFO : 0.788785183814
# INFO : tagged param count is 3618
# INFO : 2.12563553863
# INFO : 7.84713397563

is there a better way?
