Hello,
I am currently looking for a way to make the screen fade to black as a transition effect between screens using VB6 and DirectX8.1
I have looked for tutorials regarding this subject and the closest thing I could find was the 'gamma ramp' tutorial at gpwiki. Unfortunatly this example use DX7, not DX8. (this method dosen't seem to be supported by DX8 anyway)
I'm thinking that the answer has something do do with alpha blending the entire backbuffer surface, but other than that I'm unfortunatly rather clueless about how to implement this.
If anyone has any code or suggestions, that would be rather helpful
Thanks,
Chango |

Just render a black square over the entire window, and then slowly transition from 0 to 1 or 1 to 0 for the alpha component to either fade to and from black. Of course, you can change the color of the square to fade to any color you want.

Another method would to take 4 triangles, and make them open/close over the screen. Say this is your screen:
_______
|........|
|........|
|_____|
Hardcore, huh? To create a triangle-close, create a triant at each side. 2 of the points will be the complete distance of the side, and the 3rd point (the peak) will be right in the middle. Now have the middle point on all 4 sides move to the center at a predefined rate - simple. :) To create a triangle-open effect, just go from the end to beginning.
It is totally up to your imagination. Something that I always thought would be fun would to, when you exit a map via the side (in this case, up), copy the whole screen as a new texture (to prevent losing any of the view, and for simplisity sake) then stop rendering the normal game - just render this texture over the screen (kind of like a screenshot). Move it down until it reaches the bottom on the screen and out of sight. Now for the next part, just draw the NEW map onto another texture, and do the same thing but pull it down from the top.
Again, it's all up to your imagination. :) |

| I like to do what Eric posted (I've never done Spodi's transition, but it sounds cool). I usually have a graphic that is simply a 1x1 white pixel. Then I stretch it and color it and fade it to suit my needs all over the place: health bars, selection boxes, fading effects, backgrounds, etc. |
Life is short. They say "don't waste it, have fun." They're right, don't waste it...but DO redefine "fun." |

Thanks, that all actually helped out quite a bit. I chose to go with a triangle close effect that looks just awesome.
Thanks,
