I feel that another important resource for ferns knowledge is the tour in Pineapple Park where you learn that ferns play a prominent role in the movie Jurassic Park. After this video I can now say that I know two facts about ferns!

Good stuff, but I was looking for an animation showing the growth of the fern in the way real ferns grow in nature.

Great work! May I suggest topics for future content: (1) A Julia tutorial focused on the more advanced features of the language (2) A tutorial for GathVL library
@LeiosLabs
@LeiosLabs 3 года назад
I've been thinking about this suggestion a lot in the past few days, but I just don't think video is the appropriate medium for me to teach those topics. On the other hand, we really need to make better documentation for GathVL, so it is almost certainly worth doing that and making a highlight video on youtube. In addition, it makes sense for me to highlight the Julia language, but maybe not a full lecture.

What do you have to start with to make the fern? You said you would start with a bunch of points on the fern. If you start with one point roughly near the stem then repeat forever, does that then build the whole fern?
@LeiosLabs
@LeiosLabs 3 года назад
Yeah, that's how the process of a chaos game works. There's more information on the algorithm archive about it!
@farissaadat4437
@farissaadat4437 3 года назад
I don't really get how the functions combine to get the fern. If it was random like the sierpinski chaos game then once you apply the singular matrix the fern will be restricted to a line for the rest of the running time.
@LeiosLabs
@LeiosLabs 3 года назад
Right, so this was covered kinda in the algorithm archive, but the stem function is only chosen 1% of the time. That said, even if it is chosen at 25% of the time, those points are still likely to jump to either the leaf on the left, right, or upward stem when they choose any other function. From there, the stem will jump to another stem on it's new corresponding leaf. You could imagine every line in the fern to be a bunch of stems.
@farissaadat4437
@farissaadat4437 3 года назад
@@LeiosLabs ah i get you. you select the functions independently for each point, so the fern is a sort of limiting probability distribution.
@yonatanbeer3475
@yonatanbeer3475 3 года назад
@@farissaadat4437 No, that wouldn't make sense. The limiting probabilty, even if the probably of the stem function is low, should be that all the points lie on the stem.
@farissaadat4437
@farissaadat4437 3 года назад
@@yonatanbeer3475 but the other functions map it off of the main stem and into the subferns and if you do that enough then it is effectively absorbed into the rest of the distribution as long as you don't roll a 1% stem soon.
@yonatanbeer3475
@yonatanbeer3475 3 года назад
@@farissaadat4437 yeah I thought about it for a second, really the whole thing is made of of "stems" shifted around

@LeiosOS Hi, what were you studying? I'm very curious because i'm choosing an university.
@LeiosLabs
@LeiosLabs 3 года назад
In university, I studied physics. My PhD was focused mainly on computational methods in physics (namely GPGPU). As for universities, I would recommend going to the best one you can that doesn't break your wallet. Then focus on actually acquiring the necessary skills for your job (do projects / research / etc).
