      @spikeyxxx One thing I haven’t fully understood and which concerns Blender and animations are quaternions. I remember an article in the “Blender Art” magazine Nr. 31 about rotations and escpecially quaternions (imho the best explanation I’ve found so far) and the Blender foundation’s DVD about rigging. But I still haven’t fully understood it and searched the internet for explanatory videos which are still blowing my mind and definitively need a deeper insight into mathematics..

        @duerer I agree that quaternions (although they are just an extension of the complex numbers and therefore not that difficult)

        are usually explained really bad, mostly talking about a 4 dimensional hypersphere, like that is something we are all familiar with, but you could start here: https://blog.cgcookie.com/forums/topic/conors-blender-progress/

        Not the best explanation either, (spoiler. a much beter version is on the way!) but something to at least get a different perspective… (I didn’t re-read them, because I’d probably be too ashamed…)

          Thanks, @spikeyxxx, for the links 😀! You’ve pointed exactly to a problem that I’ve encountered so often: the confusing explanations. I have two videos on my “To-watch-list”:

          1. Fantastic Quaternions – Numberphile

          2. Visualizing quaternions (4d numbers) with stereographic projection

          But I haven’t done it yet, maybe also due to bad experiences with cryptic explanations from people who are surely very intelligent but for some reasons aren’t able to explain it well to non-mathematicians. And believe me, I don’t give up quickly. It’s just that these people don’t give proper definitions of the terms they’re using. And that’s when I stop the video.

            I too am a science enthusiast, which I should’ve studied in college and not Advertisement. Why does society have us pick what we are going to do for the rest of our lives when we are just 16 year old kids. Of course you’re more likely to mess your choice up, you’re just a kid.

              I was 15 and I never pursued my dream because I was too short 😢 I would never have dreamed I’d be so into computers tho, I was in my 40s when I got it btw. But as soon as I learned how.   self taught on so many levels I knew graphics was my true dream. 

              Your never too old to learn!

                  Too short? You wanted to play basketball? or maybe a professional light bulb installer without a ladder.

                        It’s a kind of self-fulfilling prophecy. If you tackle a challenge with positive thinking, you’ll find a way to succeed (as long as you don’t try to win a broad jump tournament with a broken leg or something like this, of course).  

                        With the words of CG artist William Vaughan:

                        ” Actually, the one thing you need to go past is simply the way you think.
                        It’s my experience that most people have a can’t-do attitude, especially when
                        it comes to learning new things. When I say most people, I’m not limiting
                        that to artists new to 3D. I witness this on just about every forum online
                        and at the industry shows I attend. Most people assume that things are not
                        possible, they are too dfficult, or special software/hardware is needed to solve
                        the problem. I always suggest a different approach.
                        It may sound cliché, but the power of positive thinking goes a long way when
                        working in this industry. Every day you’ll be asked to tackle the impossible,
                        and if you go in with the attitude of can do, you’ll be able to see the task to
                        completion. If your attitude is not possible, you will most likely not complete
                        the task. It’s called a self-fulfilling prophecy.”

                          I knew it, I thought I could see a resemblance, @spikeyxxx is related to my mate Albert, you know the one, Einstein, I think.

                            I kinda jumped into immediately reading the quote and assumed it was from Socrates times; “I’m not limiting that to artists new to 3D” I was like WAIT WHAT!? Socrates used computers!?

                              I’m assuming we don’t have to submit. I really thought Kent was away for a long time and the stream was not going to be for a long long while, but it’s just this Tuesday, jesus christ. Time under quarantine is behaving really strange.

                                @dostovel Yes, the old Greeks were already very progressive 😉😁! The science history books have to be rewritten!

                                  Socrates had a computer, he played Fifa football on it.

                                  By the way, talking of geniuses, two separate replies, I’ve just posted, but related to each other by the fact that the brilliant Brazillian football player Socrates died in Albert Einstein Israelite Hospital in Sao Paulo, Brazil.
