well, you got Blending in OpenGL. glBlendFunc There should even be a tutorial somewhere.... this one: Tutorial_lektion7 |

Easiest way should be to change the alpha value between 2 frames. Maybe glTexEnv could help you to set a textureEnvColor for any Texturestage. Thus you can use multitexturing for that. (I have not tested this, but should work) |

oops... yes, that's not classical blending. Flash's idea should work fine, though. |
