OpenGL variants
- OpenGL-1.0 has fixed shaders and fixed API to using them
- OpenGL-2.0 adds programable shaders but fixed pipeline api is still there for backward compatibility
- OpenGL-ES1.0 is OpenGL-1.0 with lot of "syntactic sugar". extra redundant API's removed and fractional integer API added
- OpenGL-ES2.0 is OpenGL-2.0 using programable shaders is mandatory, all old fixed pipeline API's removed
Porting between openGL variants
- OpenGL-1.0 application works with OpenGL-2.0 but not opposite
- OpenGL-1.0 application is possible to port to OpenGL-ES2.0 but needs work if it is using some of removed API's
- OpenGL-2.0 application that uses programable shaders is possible to port OpenGL-ES2.0 but may need so me work
- Porting OpenGL1.0 or OpenGL-ES1.0 applications to OpenGL-ES2.0 needs lot of rewrite to use programable shaders.
