overview
Overview
  • Applications of OpenGL ES API
    • Application Programs
    • Games & Game Engines
    • Libraries and Wappers
  • Vincent Project
    • OpenGL ES 1.x API
    • OpenGL ES 2.x API
  • Q & A
pocket blender
Pocket Blender
  • Port of Blender 3D modeling application
  • Windows Mobile
  • Case-study for porting legacy OpenGL application to ES:
    • Use OpenGL emulation layer to get started
      • In thise case: Klimt ES
    • Convert to OpenGL ES API
  • Binary License and GPL
  • http://russose.free.fr/BlenderPocket/
quake 3 arena
Quake 3 Arena
  • Port of Quake 3 Arena to Pocket PC
  • Windows Mobile 2003, 5 in the works
  • Code base converted to fixed point!
    • And many other profile-guided changes
    • Case study for porting AAA title to mobile
  • Playable frame-rates on hardware OpenGL ES implementation
  • GPL
  • http://www.noctemware.com/q3ce.html
ogre game engine
OGRE Game Engine
  • Port of OGRE to PocketPCs
  • Windows Mobile
  • Considered one of the best OSS game engines out there
  • Great asset tool chain (Collada, Blender, 3dsmax, Maya, …)
  • Porting process described in
