Hello
I am using a moire pattern with animation to create some interesting
psychedelic texture animations.
The only problem I am having is when trying to create a 30 second animation
and I seem to get a dust effect (a bit like the texure is scaled too
small).
on a 1 second animation the images do not get this.
I will have to post an image or the script tonight, as am writing this at
work.
I have tried scale to a larger value, but this does not work either.
Has anyone tried to create a moire pattern animation?
Any advice or pointers much appreciated.
Thanks

Be sure to have the antialiasing 'jitter' off, which is -j0 in the command
line or Jitter=off in animation INI file. If you don't do that you'll see
pixels jumping around with a kind of glittering effect and that sounds like
the "dust" you speak of.
Also, when working with very fine lines, as those found in moire' patterns,
you might need to set the INI to Antialiasing=0.1 (or lower toward zero) and
Antialiasing_Depth=4 or higher (command line equivalents are +a0.1 +r4).
It'll be slower but try to correct any artifacts present compared to default
AA settings.

We had a kid's book that had some pictures of objects and a plastic
sheet with fine lines that makes psychedelic effects when it's moved
over the pictures. For example, a toy top would look like it's
spinning. How would the edges of the objects in the picture be made? I
think that we have that book somewhere so I could find how they were made.
