With this plugin it should be possible to load collada xml files (*.dae) into your Ogre application.</span> |

|---|
| 65 | <span>Here a simple tutorial for using the plugin with your application.</span> |
|---|
| 66 | <ul> |
|---|
| 67 | <li>first of all setup an Ogre application (maybe found on the Ogre wiki help sites)</li> |
|---|
| 68 | <li>prepare for requirements of the plugin (see README)</li> |
|---|
| 69 | <li>paste following code</li> |
|---|
| 70 | </ul> |
|---|
| 71 | <div class="code"><pre class="code">#include "OgreColladaManager.h" |
|---|
| 72 | #include "OgreColladaScene.h" |
|---|
| 73 | ... |
|---|
| 74 | ColladaDocumentPtr daeDoc = ColladaManager::getSingleton().load("colladafile.dae", mSceneMgr); |
|---|
| 75 | LogManager::getSingleton().logMessage("ColladaDocument - import started"); |
|---|
| 76 | if (!daeDoc.isNull()) |
|---|
| 77 | { |
|---|
| 78 | // build up scene fully |
|---|
| 79 | daeDoc->getScene()->createOgreInstance(NULL); |
|---|
| 80 | |
|---|
| 81 | /** |
|---|
| 82 | * or |
|---|
| 83 | * to import only a specific part of the scene graph |
|---|
| 84 | * fetch the scene node by its unique node name |
|---|
| 85 | * |
|---|
| 86 | * ColladaSceneNode *box = mScene->getNode("Box2"); |
|---|
| 87 | * if (box != NULL) box->createOgreInstance(NULL); |
|---|
| 88 | */ |
|---|
| 89 | } |
|---|
| 90 | |
|---|
| 91 | LogManager::getSingleton().logMessage("ColladaDocument - import finished"); |
|---|
| 92 | // Note: ColladaDocumentPtr is a shared pointer and will release the resource when it goes out of scope |
|---|
| 93 | ...</pre> |
|---|
| 94 | </div> |
|---|
| 95 | |
|---|
| 96 | <p>First of all a new collada document has to be created, it takes an <span class="code">Ogre::SceneManager</span>. Everything of this document would be attached to the given scenemanager, which could not be changed for the current document.</p> |
|---|
| 97 | <p>Now an import with the filename as argument could be started. The plugin loads the full document and saves some xml nodes for fast importing. See the <span class="code">ColladaLibraryContainer</span> for further details. It holds all collada libraries, currently: CAMERA, GEOMETRY, IMAGE, LIGHT, MATERIAL and TEXTURE. Each library entity has a unique identifier.</p> |
|---|
| 98 | <p>Afterwards the SCENE would be parsed and a collada scenegraph is built up, by linking the nodes to their corresponding entities. The transformations and boundingboxes are imported too.</p> |
|---|
| 99 | <p>If import was successful, a <span class="code">ColladaSceneNode</span> can be traversed to an Ogre instance. In addition to import the complete scenegraph only a specific node can be instanced too (see example above). Now all collada specific items are attached to the <span class="code">Ogre::SceneNode</span> passed through <span class="code">createOgreInstance()</span>. Above the example takes <span class="code">NULL</span>, which means the root scenenode of the scenemanager. In fact an import of only one entity (CAMERA, GEOMETRY or LIGHT) is possible. By importing the whole scene the light(s) would be attached automatically to the scenemanager, the camera(s) too, but to activate a camera it has to be set manually.</p> |
