Interoperable 3D content with the ADL 3DR Rob Chadwick ADL
Overview Introduction Description of 3DR capabilities Tutorial on correcting common interoperability problems in 3D Studio Max Demonstration of 3DR upload Tutorial on retrieving 3D content from within a game engine
What is the ADL 3D Repository? A tool for sharing 3D content
Problem Space • Increased use of immersive learning technologies for education and training: Simulations, Virtual Worlds, Games • 3D models are difficult to create and expensive • For artists • Reusing 3D models can save them time • “On average, customers save over 20 hours of modeling time when they buy a 3D model” (TurboSquid) • For non-artists • Reusing 3D models may be all they have
3D Content Sharing Landscape Anyone Artists Sketchup COLLADA Sketchup COLLADA 3D Warehouse Artists Army Users GoogleEarth Army Users
ADL 3D Repository Authoring Environments Run-Time Environments File Conversion: DAE, FBX, SKP, 3DS, OBJ Goal: Share unclassified 3D models as openly as possible

Exporting Models Tutorial Tips and best practices
Why do I need to know this? We often receive questions about getting content into game engines and modeling tools Frequently, problems occur because content is not authored with reusability in mind We do our best to correct problems both manually and automatically 3DSMax is the most common format we are sent. We have to export these manually.
User Survey • I’d like to know a bit about you. How many of you are • Program Managers • Artists • Programmers • What is your level of familiarity with 3DSMAX?
