  • OpenGL ES 1.1 support with extension handling
  • Math library that supports fixed-point and floating-point calculations with an interface very similar to the D3D math library

  • Support for PowerVR’s POD (Scene and Meshes) and the 3DS files formats
  • Timer support with ms precision
• Input
  • Touch screen support
• Camera
  • Polar camera model (as a template to implement something more complex)
• Displays messages and Icons on Screen

    • Memory pools (generic / non-generic)
    • Memory bookmarks
    • Hierarchical heaps
    • Memory leak detection
• Resources
  • Resource streaming system

• Planned features:
  • In-game profiler
