3D in TypeScript using Ray Casting 

Can your C do that?

2:28:30 0.5 (the common factor) is being “factored out” with the distributive property of multiplication

To achieve the speed of thought of this man is my dream

Also not too sure if someone mentioned this already, I believe the problem you were having when trying to calculate the stripHeight was that you were assigning t = canvasHeight/perpWalldistance, and then multiplying that by the canvasHeight to get the stripHeight. However, you in fact calculated the stripHeight needed when calculating t, which looking at the values that are divided, is describing the direct proportion of the screen height to the perpendicular distance to the wall; aka. the larger the distance from the wall, the larger the value dividing the screen height so the smaller the strip. I very much like the solution you came up with as well with the dot products. I didn’t even think of that at first, but it is very elegant!

You're the one responsible for making me enjoy programming and math, thank you so much

29:02 You can also define an iterator on Vector2, so you can spread the object directly : class Vector2 { constructor(x, y) { this.x = x; this.y = y; } *[Symbol.iterator]() { yield this.x; yield this.y; } } const p1 = new Vector2(5, 9); doSomething(...p1);

2:47:30 ....that null check with assignment, this exact thing will be fixed in next version of typescript that already has RC. We had to wait for this just 10 years, so if you have some other issues wait for twenty-forties xD

Zozin OS wen?

Love your topic choices! Next up ray casting in the TI-84 calculator basic language. I actually wrote a hidden line horizontal 3D plot program for that calculator. 3D plotting was natively supported in the later TI calculator models.

That was impressive AF, not gonna lie. Well done!

The coding speed is uncanny. It would have taken me a month to figure this out. Lol. Cool stuff.

Ray casting almost got me to give up on programming. It was one of the first books I acquired when first starting to learn C. I was like 14 and the book "Tricks of the Game Programming Gurus" was a really well written book aimed at someone with a few years of C development. I tackled ray casting much later in life, and it was still pretty hard.

incredible video once again

thanks for the honesty toward the end of the video

Легенда! я как раз недавно считал дельты и арктангенсы для канваса)

another banger video

Finally! Another video 😄 You are my favourite coding channel, i always love to watch your videos they are my only content i watch here on RU-vid alongside with shorts haha ❤

Wow, a perfect bedtime story just in time!

Very very impressive 🎉

I will try to implement the same with tweaks, thank you, for inspiration and awesome video good sir. :)

(2:28:25) The opposite operation of distributing is called factoring.

1:02:00, you know x,y and you can calculate this cell with col/row when you know cell size, when you know cell - you can get cell bounds, in fact, you can use an algorithm similar to line drawing here

I definitely learned something from this stream. I always thought you needed matrix math to map 2D and 3D

just loved it

Great video ❤ Next up ray casting in terminal with escape codes?😂

Perhaps you were talking about the extension Tide for emacs rather than Tidy?

TS + Canvas is actually pretty cool platform for old-school graphics programming. It is like a modern version of QBASIC where you can prototype graphics before doing implementations with more involved languages and environments.

You can use the implicit form ax + by + c = 0. (a,b) is a normal to the line. Finding an intersection beteen two lines becomes easy as solving a 2x2 system. No special case for k=0.

TYPESCRIPT LETS GO!!

Classic fish eye effect rears its ugly head again. It took me a long while to find the cosine solution for it in my raycaster code as well.

That was interesting!

Great Vid!

I can't stop come back to watch it again and again it's extraordinary with such a shitty language. It's really is a question of passion for programming. Hat's off sir /o.

the DDA algorithm! Its a classic.

I like the new thumbnail ;)

I’ve only been watching you for 1 month, but I’m increasingly interested in what Linux distribution will you use?

i had a hard time keeping up with the math :(. does anyone have any resources for me to study?

1:14:35 why not just check if it's exactly equal to ceil/floor and if so, add 1. This way you can avoid the imprecision introduced by eps (what if p2 + eps is in entirely different cell)

Are we not alive today ?

01:14:30 will if(Number.isInteger(x))return x+Math.sign(dx); work?

Zozin time!

2:28:42 its called "factorisation" where you pull out a "factor" out of the expression

Thank you...

Excelente....se nota que eres un gran progamador

Any reason to define epsilon instead of using the builtin (into Number) one?

ZozinTime ✅

Cool

2:29:00 ish, ahhhh, yes, the perspective-warping problem! The best part of ray-casting wats ... Literally everyone who's done this from-scratch has facepalmed through this exact situation.

May I ask, what happened, why these two streams got removed on twitch? Something was leaked or so?

The coolest thing is my app crashes when I have more than 10 instances in tlas in vulkan

Didn't these things used to be implemented with interger steps?

Mista azozin you gotta try Julia as a dynamic language. it's soo nice

I think the playlist is out of order. This should be the first entry, but is the second!

I didn't know that duckduckgo had access to AI models

Which text editor is it?

Im in history

let me in ...

2:09:41 voidf is coming 👀

"Pure C" sounds dumb. I propose C will be called "C" and C++ will be called "HereC".

next video : porting doom to html canvas

isnt it amazing to have and actual editor that helps you? i mean, i use neovim i dont wanna sht on your emacs, its just that i dont understand why wouldnt you use lsp ...you are apparently liking it as well. So why not on other languages? I understand that compiler does the same thing, but i think its much harder to fix things you wrote minutes ago when editor can tell you instantly as you finished that line or even lets you jump through issues in a buffer

1:50:00

Game Dev is one of the hardest shit I guess

I fear you Mr Azozin have Stockholm's syndrome for JavaScript/Typescript

Seeing you program in js with you c voice is mind fucking

First

i've conflicting feeling about typescript

ur ts goes in trash can together with ur c all that bloat ware, move towards real programming in python 👌
