For the cube couldve just done: Max(Max(|x|, |y|), |z|)

[@peterhemmings2929]

That's a neat implicit formula for a cube, but you can't use it in this code, which works by defining the surface of a shape parametrically using 2 coordinates, then iterating over both those coordinates to render the shape.

[@CodecookerMintz]

Little fix, it's not dot product, just normal matrix multiplication

[@nubnoobbo]

4:15 ngl that is a pretty cool VHS effect it makes the rotating donut dramatic

[@clever4ever603]

Reading and learning about the applications of matrices is one of those eureka moments where things that seemed simple from afar become intricately beautiful up close.

i did something like the cube too, but instead calculated the cornors of the cube and drew lines inbetween them (makes a wireframe cube)

Whoa, 3D rotation is way over my head ^^ Besides that... Great video! Funny how many things can possibly go wrong :-)

[@WhateverOwO]

for the triangle and any 3d shape in general it's better to just do a ray triangle intersection test and draw the one is closer, getting the normal vector of where it hit and the light source, and putting the correct ascii. there's not a parametric formula for everything

thats cool, now make a 3d game using the console. it could be something simple like a single platformer level but that would be cool lowk and im pretty sure you can find out keypresses in c and c++ console without like typing then pressing enter like you have to in java

[@BlunnyTV]

I watched every vid need more Keep it going🔥

[@tamfang]

Do rotation matrices take care of hidden surfaces? (Nontrivial for a nonconvex object like a torus.)

[@Cxrruptwd]

actually you can apply this knowledge to make a camera in 3d space which powers 3d games.

Kid friendly Code Bullet:

[@tristan1171]

Hi mate, i'm a little confused with the maths behind the dot product. I studied this as part of my A-Levels, and I could have sworn that the dot product returns a Scalar. How is this scalar then used to plot anything? Surely you'd want a coordinate in some kind of Cartesian/Polar/Whatever space?

[@TypicalDev_1-bf9ky]

does brilliant teach linear algebra, and trigenometry?

[@Mrindia-k8n]

guys for a cube if u do a x-plane and rotate it will give a cube same for pyramid you can take a y-axis right angled trangle and just rotate it still 2pi and you get the pyramid

In the code there's an option to uncomment a line of code that then plots a bottom for the pyramid :) I prefer it without the bottom cause then you can see the insides

Hey Green Code, first of all I really like your videos and your video quality and your own style is I think perfect, and is so unique. I have some video ideas that would be super interesting to watch. Have you ever wondered about Maths, Fast Growing Functions and Fast Growing Hierarchy? I think to code the best efficient way to make the number larger, in code, could be interesting. Or maybe you can try to code Busy Beaver or THREE functions, in different ways and test their efficiencies. Please think about it if you are interested. ❤

[@erenoguz3297]

2:10 why did you take the dot product. Wouldn’t you need to do the usual matrix product. What does the dot product even mean in this context.

[@Green-Code]

Yeah you are completly right. I don't know why I said the dot product. I think it's cause I also used it later for the luminescence. What I should have said is that you just perform matrix multiplication. Aghhh! I hate when I do this, cause now I got bascially no way to correct this. I'll see if I can change the edit on KZbin studio to not include that bit, while also making sure everything else makes sense. Thanks for spotting it
