Epic and Unreal have released a behind-the-scenes video detailing the creation of ProtoStar, a real-time Unreal Engine 4 tech demo designed specifically for mobile.
ProtoStar is the first application to use the new Vulcan API, a cross-platform open graphics API that's being touted as the successor to OpenGL by its creator, The Khronos Group.
Epic first unveiled ProtoStar using a Samsung Galaxy S7 at Mobile World Congress earlier this month, drawing attention to the demo's slew of rendering achievements such as improved temporal anti-alisasing, dynamic light refraction, high-quality mobile depth of field, and dynamic reflections.
You can find out how ProtoStar was put together in the video above, or head on over to the Unreal blog for more info.
