  • @kyouko5363
    @kyouko5363 หลายเดือนก่อน +2

    I'm an expert at the low level, cybersecurity, and native programming as close to the hardware as possible. Nevertheless, my understanding of math doesn't even meet that of high school, because I dropped out in the 3rd grade of middle-school and never went back to another school, having taught everything I know, including English, by myself alone in a room with neglectful parents, a computer, and curiosity. Math is something I never picked up though after all these years, not in the direct sense anyway. I learned it intuitively by proxy of my main curiosity of low level programming and cybersecurity, but always lacked the set of terminology and a fundamental framework through which to think through, to the point where to this day I can barely read algebra. The attentiveness and consideration to having everyone on the same page, is much appreciated. The person who said "this is basic high school level math?" - I'm part of the demographic you were talking about that of not everyone being on that same page. That and the initiative to address questions and try to make things as clear as possible for just a single person who doesn't get it, makes you a great teacher.
    I have no plans on doing game dev, but having watched from start to end, this has done more for the knowledge I lack from never having gone to high school than any online course, tutorial, or anything of the sort., which all assume that you already know XYZ. The fact that you take that into consideration makes makes you unique, thank you. I feel a lot more educated after certain things clicked that I intuitively understood as it relates to a specific problem with a specific algorithm, but never on the abstract level that allows me to apply it universally.

  • @omgawesomeomg
    @omgawesomeomg 2 ปีที่แล้ว +33

    In case someone is struggling with the fact that the vector a-b gives you the vector from b to a and not the other way around, maybe this helps:
    To get from b to a, you can first subtract b (i.e. -b) to get back to zero and then add a (i.e. +a). So the vector from b to a can be written as -b+a and since we're allowed to flip the numbers (or vectors) around when doing addition, this is the same as a+(-b) or simply a-b.

    @1:15:55 - just now starting to get back into a little bit of enough time to do a math refresher again (always needed).
    This part clicked with me in a different way (vector addition).
    I know it's intuitive to some, but not to those outside of math, that it's simply taking one of the two points and "offseting" it by the amount of the other.
    A lot in math and gaming know addition/subtraction are the same as offsetting, but not all think of it that way.

    Hey megabosscat Freya, I noticed after the 1hr ish mark you mentioned that imaginary numbers are not important to game dev, but... Quaternions :)) I get what you are inferring i think, which is that it is unlikely any engine user will ever customise a quaternion implementation themselves and therefore can simlpy just use them when calling to some in-engine wrapper like Quaternion.Something(). But from a mathy POV [which you said you were coming from I think], its pretty important to represent orientations and rotations in game math, especially when aiming not to incur things like rotational edge cases such as gimble lock [when using Euler math to solve for O and R]. Your great by the way, and I'm certainly not trying to throw any shade/or corrective attitude at yuo (i've learned so so much from your content), but I think it might be fairer to say something like "they sit lower down the chain in game math where a dev might not need to know much about the inner workings, but be satisified the math has been proven so it can be used without worry of the constraints that come with using Euler method. ?? i dunno, am I wrong here, or did I misinterpret this part of this absolutely amazing long form lecture?! Thanks for all your super hard work to deliver this stuff, I literally love catching up on your latest videos. [Also, if you have time, let me know if I did misinterpret the whole imaginary numbers section on whether one should at least know about imaginary nums] 🥲

    • @acegikmo
      @acegikmo  2 ปีที่แล้ว +11

      most people who use quaternions never actually understand or unravel the inner workings, and I would even go as far as to say, most people making engines also don't really have to learn how quaternions work, you can just copy/paste code and trust the math and you'll be fine. so yeah, this is why I don't consider it important. it's interesting though!

    Lol at TH-cam UX with not being able to find the superchats. Idk why but TH-cam has a really bad UX in the app and I guess on desktop with live chat too.

    is it possible to create bouncing laser without cross product? I can't understand how to reflect ray using only dot product.
    I know that hit point, normal, and direction makes a plane that can have only 2 ortogonal. i want to get one of them to get annother orthogonal and then reflect my ray with normal and second vector orthogonal to may ray (first is normal).
    Can someone give me a hint on how I can achieve this with just the tools in this video?

      I still haven't checked it out, but I think I've found the solution:
      var pointOfProjectToNormal = dot(-ray, normal) * normal;
      var halfedVectorToMirrored = pointOfProjectToNormal - (-ray);
      pointOfProjectToNormal += halfedVectorToMirrored;
      nextRayDirection = pointOfProjectToNormal.normal; // mirrored direction

    Good video. I appreciate the work.
    The constant zooming in and out and moving around the screen towards the middle of the video drove me nuts though.
