    You, sir, are a teaching genius. I looked at this on like 20 different videos and read a bunch of different sites and articles and it was not clicking with me. I watched your video and am baffled by how easy this is. Thank you very much!

    As a Physics/Math student who absolutely adores vector calculus and vectors, in general, I loved watching someone from a different field of study go through this math and teach it, especially at 2:41 where you were calling the absolute-value brackets "line or pipe things", lol! Amazing work!

    What an amazing video despite the fact that I am not understanding the code completely 😢
    I learnt c++ so i am understanding javascript but I didn’t reach this coding level

    I have watched the Quatree implementation video and adopted it for my project. Amazing content.
    Can you make a video on implementation of weighted straight skeleton algorithm?

    Hey Mr. Shiffman, nice video!
    Have a look at the web editor sketches "angle between" and "scalar projection", they are the same (both angle between)

    How do I enable other buttons in my sketch window when it runs, so basically I need I stop button and when you click the start Button, every other button becomes disabled. Nothing work until you click on the Stop which is outside the sketch window ... I don't know jow to resolve this.. please help out

  • @tomhands7037

    in the link above to the "angle between" p5 editor sketch, you call 'rotate(v.heading())' the comment is \\Call vector heading function to get direction (pointing up is a heading of 0) -- if the vector is pointing up wouldn't the heading be 90 degrees or ~1.1 radians

    Great Video! But I do not understand why vector B needs to be normalized to calculate the dot product.

    • @DanKaschel
      @DanKaschel 2 года назад

      Because normalizing it gives it an amplitude of 1, and since it is the denominator in the dot product, it can be ignored.

    I think you should consider re-making some of your older series. No offense to you in any way but your original videos were sort of unwatchable IN COMPARISON to the content you're putting out now. You've really grown into making these videos.

    • @TheCodingTrain

      I agree! I'm trying to get to older ones but it's hard to do them all!

      Hi Senthil, the next video will be public shortly, it's just not finished and ready yet. A "preview" is available for members. (I am still finishing the code examples and closed captioning).
