The COLLADA Format and Specification COLLADA is designed to be the cornerstone of the next generation of 3D content pipelines COLLADA defines graphics concepts via the XML Schema language and an associated specification COLLADA success means widespread use, large-scale integration, and collaboration among major partners COLLADA is something we should *all* want to exist whether we are developers, middleware providers, hardware vendors, or DCC tool vendors.

The COLLADA API Goals Bridge the gap between format specification and tool integration Validate the XML Schema/specification Reduce Integration time and eliminate common bugs Provide a migration path as the COLLADA format extends and evolves Provide a basis for an extensive conformance test suite

COLLADA API Example – Setup COLLADA, Load a file _colladaRT = new ColladaRTImportExportRef; // Load a collada test file const char* szColladaFile = “model.xml”; StlDatabaseFactory factory; _colladaRT->setDatabaseFactory(&factory); //register my colladaViewer integration objects _colladaRT->setIntegrationLibrary(&intRegisterElements); int res = _colladaRT->load(szColladaFile); if (res != COL_OK) { REPORT("Runtime database failed to initialize from %s.\n\n", szColladaFile); return -1; } REPORT("Runtime database initialized from %s.\n\n",szColladaFile);

COLLADA API Example – Query an asset ColladaAsset *pAsset = NULL; int res = _colladaRT->queryAsset(”geometry”,index,&pAsset); if (res == COL_OK) { ColladaIntegrationObject *pIntegrationObj = pAsset->getIntegrationObject(); intGeometry *_intGeometry =(intGeometry *)pIntegrationObj; return _intGeometry->getGeometry(); }
