Virtual Textures For Mobile Devices
vt-mobile is an attempt to bring Virtual Texturing to mobile platforms based on OpenGL-ES, such as iOS. Currently, the project is still in an early stage of development, however, most of the basic Virtual Texturing components are already implemented and functioning.
Following are a few screenshots from the demo apps:
vtDemoPlanets: (~3GB of texture data)

NOTE: Demos in the images above are running on the iOS simulator inside XCode. Tests running on the actual devices present real-time frame rates (30+ fps).
The project is written in C++ 11 using modern programming practices and attempting to be as "memory safe" as possible, without sacrificing performance.
The code is mostly portable, but currently has a few iOS specific dependencies (namely GCD and some GL-ES Apple extensions). Currently, the only build system provided are XCode projects used by the demos applications.
