      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.

      @@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

    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.

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

    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
      @nameslastnames3332 3 ปีที่แล้ว +1

      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)

  • @tonydifonzo6953
    @tonydifonzo6953 3 ปีที่แล้ว +1

    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.

      Use atan2 function. it handles the quadrant for you.

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

    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.

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

    • @zzxoto9913
      @zzxoto9913 3 ปีที่แล้ว

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