Re: fastest way through script to get all parameters in a scene of certain 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

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.

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

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:

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.

Interesting how much choice of language affects performance.
In your tests the Object model has the same runtime as calling commands. On my
computer using Jscript, the object model is at least 4x faster than calling
Tag() command.

I suspect it to be the runtime dispatching and attribute access (dictionary
lookups) cost...
Tho the Tag command allow us to pass a collection instead of giving
sequentially items, this resulting in a great improvement.

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