Loading U3D via JS

Question

Hi;
     I tried to find in the forums but didn't find anything that worked.
     I have some u3d files attached to my pdf and I want to load them in the same annotation depending on the user input.
     I know how to reference them but i dont know how to load and render them in the same 3d annotation.
     Is it possible doing this via javascript? If so, how?
Thanks

The scene.addModel method adds an attached U3D resource as a model into the scene. It essentially merges the content of the new model with the existing scene. Here'e some source code:
// Create a new Resource with the file's URI as the argument
modelResource = new Resource( "pdf://sphere.u3d" );
// use Scene method "addModel" with Resource as an argument,
// returns top level node from loaded 3D file
model = scene.addModel( modelResource );
(Make sure to prefix the URI for the resource with "pdf://".)
if you are using Acrobat 9, you can attach resources to 3D annotations in the 3D annotation's properties dialog. Otherwise, if you are using Acrobat 8 or earlier, then follow the instructions on the following page to attach the resource:
