@fileoverview This file contains various functions and classes for dealing
with 3d scenes.
o3djs.provide('o3djs.scene');
o3djs.require('o3djs.error');
o3djs.require('o3djs.io');
o3djs.require('o3djs.serialization');
A Module with various scene functions and classes.
@namespace
o3djs.scene = o3djs.scene || {};
Loads a scene.
parameter: {!o3d.Client} client An O3D client object.
parameter: {!o3d.Pack} pack Pack to load scene into.
parameter: {!o3d.Transform} parent Transform to parent scene under.
parameter: {string} url URL of scene to load.
parameter: {!function(!o3d.Pack, !o3d.Transform, *): void} callback
Callback when scene is loaded. It will be passed the pack, the parent and
an exception which is null on success.
parameter: {!Object} opt_options Options passed into the loader. See
o3djs.seralization.deserializeArchive for details.
returns: {!o3djs.io.LoadInfo} A LoadInfo for tracking progress.
see: o3djs.loader.createLoader
o3djs.scene.loadScene = function(client,
pack,
parent,
url,
callback,
opt_options) {
// Starts the deserializer once the entire archive is available.
function onFinished(archiveInfo, exception) {
if (!exception) {
var errorCollector = o3djs.error.createErrorCollector(client);
try {
o3djs.serialization.deserializeArchive(archiveInfo,
'scene.json',
pack,
parent,
opt_options);
} catch (e) {
exception = e;
}
if (errorCollector.errors.length > 0) {
exception = errorCollector.errors.join('\n') +
exception ? ('\n' + exception.toString) : '';
}
errorCollector.finish();
}
archiveInfo.destroy();
callback(pack, parent, exception);
}
return o3djs.io.loadArchive(pack, url, onFinished);
};
