Doh Scene units was what I thought I was typing, just bad typing and spelling ;) thanks for the tip on get units out, But I would argue that loader should have the option to scale the file to the scene units if the format being loaded supports a unit size, its very rare that you would have a scene in say meters and want a model created in say milimeters to come in the size of a small country ;), Its sort of the same thing that we do in our with our imagery and elevation software, you have a projection then we mosaic or re-project every thing passed to the required projection no matter what the source projection is of each component.. BTW I not i'm not suggesting you to do this, just that for me and my 20k+ users this would be a good thing some time down the road, _____

I think this function is best done outside the plugin. In the current SVN you can do this using the DAE object and document name returned by the plugin. You need to get hold of the correct domCOLLADA object and then call getAsset on it to get hold of the domAsset object and then call getUnit in that to get the information you need. If you do put any scaling transforms above the model then remember to rescale the normals back to unity as well! stateset->setMode(GL_NORMALIZE, StateAttribute::ON); Roger _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gordon Tomlinson Sent: 23 November 2007 15:24 To: 'OpenSceneGraph Users' Subject: Re: [osg-users] Proposal to change the way the Collada pluginhandlesthe DAE object Need to add scaling the loaded model to correct screen units ;) ( worth a try ;) )
