Hi, I'm writing some image effects for an RPG and want to try and create an effect similar to the ones used in FF7 and FF9 (and probably others that I haven't played) when the view spins around and blurs right before a battle. Assuming I have the frame I want to spin and blur (I don't know if there's a more technical name for the effect) rendered in a buffer, are there any ideas or references on how I might achieve a similar effect? Any advice is appreciated.

Not fade, but blur. I guess it's kinda hard to explain, I'll try and get a couple of screenshots today and post a link to better illustrate what I'm trying to do.

By fading together several different views at different angles, you do create a blur. Your render function should look as follows:


texture t;
draw scene;
grab an image of the screen and store it in t;
for(angle = 1; angle<360; angle+=whatever) {
rotate camera;
draw scence with 50% transparency;
draw t on top of scene with 50% transparency;
grab an image of the screen and store it in t;
}

Hi, finally got the screenshots. I misplaced my DVR and had to use an emulator, which only supported the effect for FF9 and not FF7, so the only shots I have are from FF9. Unfortunately, I think these are a little more complicated than FF7's, but they should give you a good idea.
