In my on-going quest to improve load times when dealing with Collada (DAE) models in Papervision3D, I decided to write a DAE file cleaner (or optimizer) in Adobe AIR that will remove extraneous information from the DAE file that Papervision3D ignores anyway.
I do all my modelling in 3DS Max 2010 and it exports lights and so forth that are unused in pv3d and might as well be removed to save on filesize.
Additionally, and more to the point of what this post is all about, I have written a new class for Papervision3D which extends the DAE class and provides for loading zipped DAE files – this *really* crunches down the file size.
See example usage here and download a copy below!
var autoPlayAnimation:Boolean = false;
var DAEName:String = "MyColladaModel";
var loopAnimation:Boolean = false;
var myDAE:DAEz = new DAEz( autoPlayAnimation, DAEName, loopAnimation );
myDAE.addEventListener( FileLoadEvent.LOAD_COMPLETE, onModelLoaded );
var zipFilename:String = "mymodel.zip";
var asyncParsing:Boolean = false;
var myMaterialsList:MaterialsList = new MaterialsList();
myDAE.loadZippedDAE( zipFilename, myMaterialsList, asyncParsing );
