Wear you favorite R/C anaglyph glasses and look at this 56kb video. It may be interesting for web design ... Giorgio.  | ||

Good ! What equatos for the transformatin to he anaglyph did you use ? Luminance in the R and B and no chnages to green ? | ||

Thanks Michal, I'm glad you like it. I'm trying to demonstrate that GIF format is the best way to encode anaglyph images from not-textured CG: small files and multi-platform compability. I've been more detailed on Holostereoitalia mailing list; as far as I remember you're a member of Holostereoitalia - feel free to e-mail in english to me or to the group for more info. I cannot tell you about the math behind this encoding because I don't really know; this is the way how it has been built. I created the moving starship in 3DSMax and I rendered separated left and right AVI files using XIDMary. To create the anaglyph I coudn't find a Video-Post filter meeting my needs so this is what I've done: 1. I started a new 3DSMax scene with a large and thin parallelepiped: my screen 2. I created two light in the same point in front of the screen and I enabled the projector feature of lights. 3. One projector loaded the left AVI with settings: R=255, G=0, B=0. 4. The other loaded the right AVI with settings: R=0, G=255, B=255 5. I defined one window as the point of view of the projectors and rendered the superimposed images as a new not-compressed AVI file. 6. I turned the big 24-bit 31-frames 320x240 AVI file (7 Mb) to 8-bit animated GIF (56kb) Generating an anaglyph in this way you'll get a lot of parameters to be varied, for example: - background colors of the two AVI - color of the screen - overall brightness and position of lights of the final scene - RGB parameters of projectors .... Well, the whole job took only one hour but at least two things can be improved: 1. lights of the final scene have to be changed: you can see an not-intentional "circular" background 2. the image has to be cropped: you can see the border or projection. But I'm sure ghosting can be reduced again with an accurate setting of all parameters listed above. CAN ANYBODY FIND THE TIME TO GET SOMETHING BETTER? THX, Giorgio. | ||

Thank you for your information ... Creating the anaglyph by the help of different light color adjuting is an interesting idea ... It shuld be interesting to chack if this method gives better result than post-combination by some filter ... | ||

Hi everybody, wait the image to be loaded: it's a 183kb file. Another R/C anaglyph but to reduce the file-size I defined the color depth to 5-bit = 32 colors. It's enough to enjoy it! Giorgio.  | ||

I reduced the size of the images. Max upload file size for this board is 150Kb, now the GIF is 116 Kb Giorgio.  |
