Question

How come? I like this aberration but can't make it a feature

Hi,

 

I really like the stripe lines aberration and it could be appealing in some designs.

It only occurs on scaled down image in After Effects screen.

I was doing solid style cubes via layer up, which I also like.  When I did a single line cube shape I noticed it there and thought my work needed fixing, instead I layered it up, and found to be sweet but only on small scale in after effects.  Render cleared most of it out.

Can anyone explain this, I'm sure it is very common.  If it is aliasing it seem to rectify on scale up.  I also had rasterise on.

 

Thanks

Myf

It looks like you have 3D layers offset by one pixel. Classic Rendering 3D layers have no thickness, so if you stack a bunch of them up and they are offset in Z, then you look at them from the side with a long lens camera, many of the layers will have thin lines between them. If you use a wide-angle lens camera, there will be fewer layers with space between them because of the difference in parallax.

 

If you change the Magnification Ratio of the Composition Panel, the artifacts will change in appearance because of how the image is resized. The same thing happens in a media player when you resize the video. Your slightly less than 1-pixel lines are caused by the anti-aliasing that is going on when you resize will look different than the video would at 100%.

 

I hope this explanation helps.

Thanks, I was intending the gap and I enjoyed the effect.  Very happy with end result but need to work on the 'registration' of the shapes to make a cube just right before turning it into a rectangle, etc.  Cube from shapes (stroke line edges only no fill) is a little different to using solid to make a cube.  I seem to have to make small adjustments because of the stroke lines making the shapes a little bigger than their easy to manage pixel 300 x 300 dimensions and the xyz.

Your explanation helped.

Thanks Rick.
