    Default Moire Illusion

    Hi everyone! I am fairly new to the whole graphics thing so pleas bear with me. I am looking for some guidance on how to make the Moire effect on Windows base OS. Basically I want to take an image and process it with the right program so that I can print it off and create an animated illusion using an vertical stripe pattern. So I guess I need to start with the program first, can anyone suggest one? Also any other information or help about how to create the Moire illusion will helps.

    Thanks

    Hello dappie,

    Welcome to Talkgraphics.

    A printed moire pattern will not animate unless it is moved, either the viewer moves or the media it is printed on moves.

    The pattern can be created with all graphics applications I know about.

    Personally I use Xara Xtreme.

    The first attached image shows some vertical lines. The second image shows the moire effect with a clone of the lines rotated 5.

    Hi Soquili,

    Thank you for your reply.
    I will definitely check out the Xara Xtreme.
    I am assuming to create the moire pattern you need to enter some values for the variables. So I guess my question is how do I know what variables to enter for the foreground vertical line image to work with the background image. I guess a video will best illustrate what I would like to make.

    No variables, Xtreme is a vector drawing application.

    Simply draw a line. For example a 200 pixel vertical line

    Decide how much spacing you want, say 2 pixels.

    Set the duplication distance in Options to 2 pixels for x and 0 or y. That is x and y as in graph paper coordinates.

    Use Ctrl+Alt+D keys to duplicate the line as many times as you want.

    Once you have the lines select them all and group.

    Use Ctrl+K keys to clone the group.

    Enable the rotation handles on the clone group and drag a corner rotation handle and move the clone so it give the moire effect you want.

    Sounds complicated but can be done in less than 10 seconds.

    How about the image itself?
    The one that is behind the moving slide.
    Are there any particular setting for the Moire patterns?

    Bill's post might make more sense if you download Xara Xtreme 5 trial and follow his steps.

    Perhaps a video may help.

    No audio in the video.

    Using a blend of lines around a circle displays a more dramatic moire effect.

    Reminiscent of the Optical Illusion thread started a while back by Rik. A similar effect was created by using offset circles.

    Check it out,
