this is a rundown of the renderers available in Umfeld and how they are supported on various platforms:

  • OPENGL_3_3, shader-based version with core profile ( no fixed-function pipeline )
  • OPENGL_2_0, legacy version with fixed-function pipeline
  • OPENGL_ES_3_0 :: used for iOS + Android + RPI4b+5 @note( has not yet been implemented in Umfeld )
  • SDL_2D :: built in software-renderer @note( has not yet been implemented in Umfeld )

note, that only OPENGL_3_3 and OPENGL_2_0 are half decently implemented. all other renderers are stil VERY much work in progress and lack most features or do not exist at all ( e.g OPENGL_ES_3_0 + SDL_2D )
