Thank you You are such an angel❤

[@WowPlusWow]

You are a god amongst men

[@IARRCSim]

Thanks. Why MVC and rotating around an arbitrary axis is mixed together is a mystery to me. They have nothing to do with each other. One is nothing but computer science and the other is completely math.

[@sharadsharma3176]

@@IARRCSim No, math is useless if we don't implement it. Computer graphics is not only dealing with math but also about how well we can implement it.

This is the best intuition about camera transform I've ever seen

40:40 Oh I see it ... mind blown. That small exercise is great from just an algebraic understanding of where dividing by **w** is the conversion step from 4D data to 3D projection. Neat! rational splines sounds like a fun adventure, i'll have to put it on my list

[@jolanmoussier9267]

hope ur good at maths aha

[@zzxoto9913]

At 23:53, when calculating phi, phi could be written as, phi = arctan(yv / zv), since xv is 0 for YZ plane.

You are right he males me doubt through good teacher

Through not through

This guy is a legend.

[@phitsf5475]

Great lecture. At ~28:00 he starts talking about "Quaternions". 3Blue1Brown has an excellent video on this concept if anyone has not seen that yet.

[@mashug1731]

3blue1brown the best

[@rayandrewbuensuceso6879]

Loved that 4D discussion tho I was only searching for the rotation of axes lol

[@m4tin_e]

would you please tell me , where is the website of resourses ? becouse the link on the fisrt video dosen't work sadly.

[@rambololal]

nicely explained :)

[@tonydifonzo6953]

If your code is NOT working... You need to account for what OCTANT the axis of rotation is in (atan does NOT work in all octants). Also, with Z positive pointing into the screen (opposite from convention) just flip the sign of the Z component of the axis of rotation.

[@michaellundgren6949]

Use atan2 function. it handles the quadrant for you.

[@Linaiz]

Question: Instead of aligning the v vector with the z axis, could we align it with any other axis? Any particular reason for choosing the z axis?

[@nameslastnames3332]

Any would do, as long as one knows what they are doing (I. E. steps would have to accommodate for the fact a different axis is used)

[@patrickmultimedia]

where the hell are the CPPS??? i wanna learn!! the link doesnt work im in chile

[@toubi1657]

good lecture!!

[@neerajkrishna1983]

Omg! blew my mind!

[@mechi4978]

13:03 rotation

[@rweaver6]

Does he have the right hand rule wrong??

[@breakdancerQ]

Nah, he's just using the left handed system which I don't think matters here at least.

[@rweaver6]

@@breakdancerQ thanks for confirming. The left handed convention indeed yields the polar opposite definition of the right handed one.

[@TheRayll]

brilliant

[@sqeye]

please list the other lectures in series in video info. next time use a more searchable titling system, remember our library is Google as pointed out in Lecture 01.

[@jinxblaze]

nice

[@picosdrivethru]

there are four of them, i hear they are in a gang

[@naqiongtradingllpnaqiongtr8035]

Can u explain what the True meaning of "Arbitrary".....!! Especially Canadian PM.. say "Arbitrary China"

[@zzxoto9913]

Most often use of the word "arbitrary" could be replaced by "any".

QT sucks....waste of time

[@fas0f]

not really, the theory has nothing to do with QT so you can still apply it to w/e u want...
