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 );

certain value?
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?
