Interesting examples of aliasing.

Enjoy.

Very cool, I like it! Your title doesn't do it justice, it should have been something about an optical illusion animation technique.

 

[phoenix79]

Very cool

"my brain just got owned" "you are The One." LOL

Anyone know the music? Very beautiful.

Tutorial on how to make animations like this

 

[thomsbrain]

That was very cool.

 

[dennilfloss]

It's like the old zoetrope and praxinoscope animations.

I refuse to accept this. This is amazing

 

[zinfamous]

that was rad.

Bitchin'!

Very cool!

First thing I thought of was those plastic ridged toys you got in cracker jacks that as you tilted them the image changed to show motion. Same concept.

I don't know what this type of illusion is called, but there is a series of books on amazon that use this same effect:

love it!

It isn't aliasing though, there are no sinusoidal patterns here, it is just taking advantage of the fact that your brain will fill in the gaps between between the white spaces based on known shapes.

My definition of aliasing could be off, but I didn't think aliasing only applied to sinusoidal signals. There's aliasing in images and by their intrinsic nature they aren't sinusoidal... although you could use fourier analysis to analyze the images

 

[Demon-Xanth]

Aliasing doesn't need to be sinusoidal. It's a signal that is different from the actual signal due to sampling rates. An example of one I've dealt with in RL was a scope's sample rate that made a pulse train look like it would jump up in amplitude and slowly fall, when in reality, nothing changed.

 

[rasczak]

pretty neat.

thanks OP.

 

[Flipped Gazelle]

That was swell.
