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

[Matt Lind]

Retrieving the value is the same.  If you use the object model you'll have 
direct access to the parameter whether it's the tag or the value.  Just switch 
"oParameter.Tags" with "oParameter.value" in my example and you have your 
answer.

If you're looking to retrieve a specific value, or parameters with a common 
value, then you have no choice but to loop through all of them and do 
comparisons to find what you're looking for.  In your case using the other 
notation with wildcards is only useful if you're setting a set of parameters to 
a common value.

sorry, i wasn't really clear.  i'm aware the tagging bit was slow, i couldn't 
be bothered to tag it object modelwise.

i'm referring only to the value retrieval of the parameter.  not the setup time.

again:
# INFO : 0.788785183814 seconds <--- accessing 3618 parameters's values by tag

# INFO : 2.12563553863 seconds  <--- accesssing 3618 parameters's values by 
GetPropertyFromName2(propertyname).Parameters(paramname)

# INFO : 7.84713397563 <---- accessing 3618 parameter's values by 
Property(propertyname).Parameters(paramname)
tagging is by far the fastest, but in imo, is unacceptably slow.
compare that to a method such as IsSelected(), getting a report on a large 
number of objects is negligible.

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

is there a better way?
