EMERGENT SPACE TECHNOLOGIES HAS DEVELOPED THE OPENFRAMES APPLICATION PROGRAMMING INTERFACE (API) AS A CORE COMPONENT OF OUR ONGOING NASA PHASE II SBIR (NNX16CG16C). OPENFRAMES ALLOWS 3RD-PARTY APPLICATIONS TO DISPLAY HIGH-FIDELITY INTERACTIVE 3D VISUALIZATIONS WITHOUT HAVING TO DIRECTLY WRITE ADVANCED COMPUTER GRAPHICS CODE. AS A PART OF OUR PHASE II WORK, WE ENABLED THE VISUALIZATION OF MASSIVE POINT CLOUD DATA IN VIRTUAL REALITY (VR) WITH OPENFRAMES, WHICH HAS MADE IT PARTICULARLY USEFUL TO THE NASA GSFC VIRTUAL LANDSCAPES PROJECT. WE WILL CONTINUE TO MEET THE NEEDS OF THE VIRTUAL LANDSCAPES PROJECT BY DEVELOPING THE ABILITY TO RENDER INTERACTIVE USER INTERFACE (UI) ELEMENTS IN OPENFRAMES, AS DETAILED IN THIS PROPOSAL.
