I can't hear êx or êy anymore after making this video.
Somewhere in the future, I'll probably make a part two which will discuss more advanced matrix operations e.g. determinant, inverse, ...

this is truly a goldmine, i love it so much

[dandymcgee]

This is some Khan Academy / 3blue1brown quality content right here. Amazing work. The visualizations are incredible.

[CosmicComputer]

I was pining for another entry into the series, can’t wait to watch this when I get home from work! Thanks for awesome content as always!

[raunaksrarf]

I had 100 doubts, and u sir reduced it to NONE

[Khan-bqqc]

this video is really good, you cleared many of my questions
I'm still not sure how all of this will be applied to game deving tho, if anyone could give me an example I'd be very glad

[yolamontalvan]

Thank you professor. I didn’t know how importan were the matrices in game development. You forgot to mention what software you used to make those amazing 2D and 3D graphics.

[hugoespinosa]

Excellent video! I love it. How did you make it?

[khellstr]

Thank you. This was very illuminating.

Questions at 15:00 :
(1) Should those three rotation matrices also have the fourth columns and rows as the previously shown scaling and translation matrices have?
(2) I thought there was a matrix that could rotate around any arbitrary axis, is that not a thing?

[박성우-nl]

Amazing work! you saved me, Thanks a lot!

[glaze]

When rotating, why does the green vector x coordinate is -1 * sin instead of sin? is it because it ended up in the negative side of x axis? Is there another rule to explain this?

[ian.ambrose]

Excuse me, why didn't you include matrix reflection?

[truthphilic]

Which applications did you use to make the graphical contents?

[nic_bo]

why no one explain visually transpose Matrix 😭

[RagibMahirAshhab-snqv]

not everyone will come here for game dev.

[Boxing_Gamer]

You already lost me at the hats, which you didnt bother much to explain. What is transformed, the coordinate system or the arrow? Gibberish

[ferudundogusyilmaz]

Great video. Only have one question. If you first shear and then rotate, to project it into the first coordinate system, you first have to multiply with rotation matrix and then shear matrix. You did it reverse. Why?

[SquareTales]

Lol only 200 views? I mean this is very special content but very well made. Thanks a lot.

Your mouth asmr sound is irritating
And disturbing .
If you are willing to you should improve your audio setup qualities or change it.
Thankyou .
