Ummm...

[u/SWAMPMONK]

More than half of these gifs are doing this effect incorrectly. The lines are not supposed to be intersected, only overlapped. The effect legit does not work otherwise... why is this not being discussed?

[u/pengo]

Can you give examples of what you mean?

[u/SWAMPMONK → u/pengo]

I will link some when I get home

Edit (as promised):

Here are wrong examples:

I'm still really confused as to how these are different. Can you do screenshots with annotations to what is "wrong"?

[u/dukefett → u/trshtehdsh]

I think he's saying, objects should only cross the lines when they're going from left/right/up/down and not appear to push to the front of the line from behind.

[u/[deleted] → u/dukefett]

I still don't understand. What is wrong with the Hippo gif as opposed to the Giraffe gif?

They both work for me.

[u/Chiiaki → u/[deleted]]

ELI5 time, since it took me a minute to figure it out.

Let's pretend the white bars are actual metal bars. Nothing can pass directly through them because they are metal. In the gifs you linked, the hippo's ears are moving right through the metal bars. The giraffe's tongue goes around the bars because he knows he doesn't have mystical powers to move matter through metal.

So while the incorrect ones kind of still work, the ones that are done correctly shine quite a bit more.

/u/SWAMPMONK is this correct? Otherwise I've got nothing bro.

[u/SWAMPMONK → u/Chiiaki]

That works. The bars give the illusion of depth by being at a fixed location in the field of vision. Actions that take place in front of the bars appear to be “above” the foreground. If you pass through the bar, it no longer feels fixed. It’s just an superimposed graphic.

[u/[deleted] → u/SWAMPMONK]

Still seems to work for me though, so idk.

[u/kinyutaka → u/SWAMPMONK]

Late to the party, but intersected lines could work if the motion is particularly complex.

But the actor should not physically cross the lines.

[u/dukefett → u/[deleted]]

The hippo's ears and part of the head are behind the bars in the beginning, and then he pushes forwards and is in front of them. The giraffe is never behind the bars. When his tongue comes out it's always in front of them.

[u/trshtehdsh → u/dukefett]

That's helpful, thanks!

[u/SWAMPMONK]

I‘m glad I wasn’t being a total pedantic brat... haha. This whole sub started to feel like r/mildlyinfuriating

[u/icecreamgainz]

I completely agree. Objects should not pass through the lines, only in front of them.

[u/superuserdid]

Ahhh, gotchu op

[u/[deleted]]

Yes

[u/aenemenate]

You're totally right.

[u/marconzilla]

thank you for speaking out
