    Single Image Stereogram

    Hi All,

    I have written a small python script to generate stereograms from blender.
    If you are interested, download
    http://www.sulyok.hu/~peti/blender/stereogram.py and put it in your scripts dir.
    Then download http://www.sulyok.hu/~peti/blender/stereogram.blend.
    Open it.
    Choose Scripts -> Update Menus.
    Choose Scripts -> Wizards -> Stereogram
    Press Generate in the scripts window, and see the result saved as stereogram.tga.

    I would like to know what you think about it, or if you have some suggestion.

    BR,
    Peti

    Wonderful idea!
    I've just tried the stereogram.blend, the resulting tga shows the two rings in 3D but wit some (unrilevant) errors. The ring on the right seems to be broken and that on the left seems to have a square on its surface (seems to be 'over' the ring). But really good!

    A suggestion could be the possibility to generate a full scene for a sird video

    Thank for your work!

    Could you explain how is the right ring broken, and where did you see that square on the left? I could not find such errors, or I did not get what you meant.
    I have just noticed that I left rendering size at PAL. The default setting suits FULL size better. "Pattern Width" and "Levels" should be decreased for smaller images.

    Video is a good idea. The only problem is that I have tried to render the stereogram using the generated image, loaded as a texture on a plane, viewed by a camera. The result was a bad quality PNG image. I guess a rendered video would be something similar. I can imagine generating several TGA images, loaded into GIMP and create a video, but that is more complicated than just pressing the GENERATE button in the scripts window.

    I have put the rendered PNG here:
    http://www.sulyok.hu/~peti/blender/stereogram-ri.png
    and the settings here:
    http://www.sulyok.hu/~peti/blender/stereogram-ri.blend
    The rendered PNG seems blurred after seeing the TGA.
    I do not know if the quality is lost during compression, or the scene setup is suboptimal.

    Dear speti,

    Turn off oversampling, and you will have a razor sharp rendered image.

    I have fixed the stereogram generating in stereogram.py. Now the image is rendered by blender in a new scene. Animation is also available.
    Now it's worth to check it again. There is a new example blender file of an animated stereogram:
    http://www.sulyok.hu/~peti/blender/stereogranim.blend
    ...and an example video: http://www.sulyok.hu/~peti/blender/stereogranim-PAL.avi

    This all sounds awesome! But I can't download the script. Anybody know of another place to get it?

    I'd love to get the python script, too, but the link seems to be broken. Can you update the link, please?

    THANKS!
