Hi
i work on a Myst IV-like game engine with delphi7 and OpenGL . I need to to find a way to do transitions between two texture.
I want to blend two texture into one.
Anyone can help me?

Thanks
JP

well, you got Blending in OpenGL.

glBlendFunc

There should even be a tutorial somewhere.... this one:

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.
