Explore building a realtime sandbox toolkit for Android VR app developers in this 52-minute conference talk from Big Android BBQ 2015. Learn about rapid prototyping techniques to lower the VR barrier to entry, combining scripting and live shader updates over Firebase with devices like Project Tango tablets and Android Wear. Discover how to get instant feedback when creating VR spaces and experiences in the Android ecosystem. Cover topics including 3D concepts, OpenGL basics, Cardboard SDK integration, shader programming, and advanced rendering techniques. Gain insights on iterative geometry, deformations, texture mapping, and guided VR experiences to accelerate your Android VR development process.
