Hi,

I have a general implementation question where I am not sure what the best and speediest solution would be.

What I want to do is scroll huge images at reasonably fast speed, preferably in 3d so I can use a 3d camera to zoom in and out or fly over the images with a bit of an angle. Imagine it quite similar to google earth, just without the need to be placed on a sphere, but rather on a plane and the camera like a bird flying over.

The upper limit of the size of the images would be ideally around at least 8000 pixels wide and high. Now needless to say i cant load them in as is, but was thinking i chop them up beforehand in more consumable tiles and then load the required tiles in dynamically, depending which area of the image the camera is hovering over.

This hopefully shouldn't be too complicated but what I am wondering is how to do fast zoom in and outs? At some point I would have to change the resolution of the tile and i want this to happen as smooth as possible. Would it be possible to just switch resolutions by loading in a higher res image when at a certain distance? I wonder if this would be fast enough or if I should have 2 layers which i fade in and out above each other, whith each layer containing a different resolution. Ideally you would only notice the changes in resolution not in a big rerender, but a bit interpolated in between.

Probably I should just go ahead and try it out, but I was thinking I ask first this time, to get a better idea.

Thanks a lot for any insight and help,

Tommi
