http://www.flytyingclips.com/chung.html That is very cool indeed. I did 3D programming (in Ope-Inventor and OpenGL on SGI boxes) for several years. I'm guessing, but I assume there is some 3D interpolation going on there. A half a dozen or more photographs, taken at regular 360' intervals, are fed into a program that fills in the blanks, much the same way 3D tomography is done. I've seen rotations of electron and confocal microscope images put together in a spin like that, where software takes out blurriness due to depth of field, and splices it all together so it looks like a continuous view. I'd like to know what flash software did that. |

It doesn't have anything to do with 3D--you can only spin the image in one axis. I'll bet this is 2D frame-to-frame pixel morphing. The user takes 4-8 still photos in a regular axis rotation. Then something vaguely like Xmorph interpolates a bunch of new frames between the original image points. How that happens in semi-realtime is a mystery. This is no giant animated gif. That would take too long to download. There are a few image editing groups on usenet. Maybe someone out there really knows. |

Its an imaginative way to show the fly, but I don't see any fancy graphics. -- Cut "to the chase" for my email address. |

I think they took fewer exposures, and then used software to interpolate the intermediate frames. Way out of my depth, but I'm curious. Is there anything visible which tends to support one theory or the other? Or are we dealing with speculation based on considerations other than what appears on the screen? Wolfgang |

If you do a search on http://outdoorsbest.zeroforum.com/zeroforum?id=68 you will find the post somewhere where the guy described how he did it, and that is was time-consuming to do. There was a short thread on it. Some time around the beginning of last year I seem to recall. MC |
