It took me up until reading your comment to get this one. “Is it that the scaling transformation only scaled the y-axis??”
radicalautonomy@lemmy.world 3 months ago
I teach these basic transformations as part of my middle school math classes, and I was completely loss as to why they didn’t include a reflection, but then I realized a reflection wouldn’t be that interesting because it could be indistinguishable from a translation.

Don’t use this. It’s not a lossless transformation!

Meanwhile, in SVG:

Goddammit. This is like getting rickrolled.
ICastFist@programming.dev 3 months ago
We rarely get rickrolled anymore, such a loss

Goddamnit. This is like getting rick[rolling something involves flattening it]
The_Che_Banana@beehaw.org 3 months ago
Is this science?
…seriously, I’m at a loss

The second is not really scaled, and the second and forth have translation. Usually that wouldn’t be a problem for demonstrative proposed, if translation wouldn’t be shown explicitly. Can be fixed by introducing a canvas of the before/after picture
jol@discuss.tchncs.de 3 months ago
The second is scaled in one axis, and had translation otherwise it would be hard to understand. And the rotation can be achieved by moving the origin of rotation.

Ok … I didn’t know this meme (too old and/or out of the loop I suppose) … so out of annoyance I looked it up …
… and yea … as far as trolling is concerned gotta pay the game here … not sure it was worth 15 mins of my life but … kudos I guess
jaybone@lemmy.world 3 months ago
I don’t get it.
Hjalamanger@feddit.nu 3 months ago
Only the transformations one is correct. All the other ones seemingly also preform a translation, and even if they might be correct if you take the orgin to be slightly outside of the shape but that’s bad for educational purposes. Also this one makes the translation transformation look like the identity transformation.
This last one might just be me, but shouldn’t shearing be included here?
einlander@lemmy.world 3 months ago
No shear is disappointing.
half_built_pyramids@lemmy.world 3 months ago
Yeah, such a big loss it wasn’t included.
apocalypticat@lemmy.world 3 months ago
Scaling looks like scaling+translation? And rotation looks like either rotation+translation, or scaling+translation?
Soulfulginger@lemmy.world 3 months ago
That’s because it’s loss
apocalypticat@lemmy.world 3 months ago
Oooh🤦♂️

Um
The second wrong.
Or…only one
