amazing explanation, thank you so much

Allelouia!!! This video is amazing!!!! Bravo for all the preparation work to make the subject understandable!!! I discover your channel today. I will look at the rest very closely. 1000 times thank you!

@21:43 are you using the Math3D library by Stephan Soller?

Try using Lex and Yacc for this.

so good! please make 3d engine course!

if you are on macos and installed sdl2 via homebrew, you can get the installed paths by running sdl2-config --libs and sdl2-config --cflags and the run gcc like this gcc -Wall -Wextra -I/opt/homebrew/include/SDL2 -D_THREAD_SAFE -L/opt/homebrew/lib -lSDL2 ./src/*.c -o game

In C, a return value of zero indicates that the program has completed successfully. Therefore, a value of 0 should be returned.

Hello Dr. Gustavo, do you have any plans to create a course in the field of AI in game development?

Excellent Pikuma, also your website is down

I finished 4 of your 10 courses (still working on 2), and the one about Computer Graphics Programming really stands out to me. The others are also amazing, but the graphics one really opened my eyes on another level. Are you maybe planning to make another course in this field? Maybe about Raytracing or even a graphics API. Would be awsome!

Looking forward to every Christmas/New Year for your videos. Always excited, never disappointed ❤🎉

Well, this was a treat, thank you. Merry xmas. Too bad i didn't have my notebook while watching this🤔 say, will you ever do a course specifically for game AI i.e finding paths in SDL2/3?

Any plans to make a course about raytracing or shading?

Happy 2025 everyone! 🎉 😊

any plans to make a course about algorithms and data structure?

Christmas present! 👀

Very good! Any thoughts, is semi-implicit Euler and Verlet the same thing?

When we move from points to sticks. The system is no longer conserving energy. It is loosing energy. What's the reason for that? Also what numerical methods are used for calculating mission trajectories and planetary orbits for space missions?

bro coding on GameBoy Color

I'm having a very difficult time finding info on the GTE and GPU architectures. Any info on ALUs, and the execution units contained?

In the case of updating a stick where one point is pinned and the other is not, shouldn't the adjustment in the position of the point that is not fixed be twice what it is as implemented in the current code? Otherwise it seems that you are adjusting the stick position only by half of the actual difference on length change.

Can u explain why you are returning 0 for failures and 1 for success? In c++ i was taught the opposite

excellent explanation..

13:05 What could go bad if free is used for de-allocation but destructor is not used? I mean instead of delete if one uses only free what would happen?

I wish you had a complete course teaching just C C++ with what's happening in low level like this. Like showing how function pointers lambdas and call backs are used ect. also showing how OS internals and drivers interact with the code ect. The internet lacks that systems level of C/C++ teaching.

Even back when we could directly access hardware from user level software, without an operating system abstraction our software had to know the hardware. CGA, EGA, VGA, or something else for video? What kind of sound hardware?

Hello. I am encountering strange errors in Windows. Please help me run the file.

Also, I don't think we ever cared about the small overlap, z-buffer usually handled that

Hmm, what Hmm, what I did in the good old DOS days was to first split the triangle into two so that in the middle there would be one vertical edge. In case the top or bottom was vertical, this step could be ignored. Then I would calculate the slope per row for the left side, eg 0.3px/row. Then do the same for the right side, lets say 0.4px/row. Then would calculate delta length per row which was how much the each rasterized line would grow per row, and would be the sum of both slopes. Then I would just iterate from the top, fill the cur_row_length of pixels, move the start_x_pos by left_slope and inc/dec the cur_row_length by delta_length. And loop until I get to the middle vertical line, or the end vertex of the triangle. To get gouraud shading on this, I would calculate similar deltas and slopes for the color gradients and inc/dec those per pixel and row as needed. Simple rasterization on MCGA 320x200x256c DOS screen. Well, there was extra step to map the current RGB to palette/dithering color.

Great video. Do you know how to implement a vector class in C++ like that used in Tradestation's EasyLanguage which can accommodate multiple data types within the same vector?

Canal incrível amigo! Eu vim pela indicação do Fábio Akita. Para quem está iniciando na programação, qual dos cursos do seu site você indica? Tem algum vídeo que fala qual ordem dos cursos fazer? O valor do cursos é em Dolar ou Real?

I grew up in PS1 era and was inspired by playing the games back then. I feel that ideas brought from that era could give new soul for the modern development. Going back to this lost art ignites something in me - thanks for this man. Learning hardware reversing sega or ps1 architectures - less complex tech, more solid fundamentals.

bit shifting is the foundation of all

I'm hoping to create a ray-casting algorithm (similar to the original Doom and Wolfenstein) and using this as a starting point. Wish me luck!

Great videos. Just one thing though - "quad" is pronounced "quod", not "quahd".

this is awesome

Amazing! i'll create an anki card for that

Intresting as fuck

Hey Gustavo, I am interested in both types of projects: the DOS port + performance optimization (which has plenty of real world applications depending on the context) and the implementation of other types of pseudo-3d algorithms (they are always so much fun to watch and learn!). Great great video, I finally managed to watch it till the end! You rock!

You never said anything about the technical differences of the OSes.

I've always heard about Verlet integration and never fully understood it. This video made it not only understandable, but intuitive!

Parabéns pelo video, no inicio tinha certeza que tu era BR ai fui ver seu twitter e voila kkkkk melhor video sobre rasterização no youtube !!! Se quiser fazer um vídeo sobre gaussian splatting ou nerfs um dia pode me contactar.

I wish there was more C content, you finish C programming playlist by watching and writing useless stuff and don't know anything about development after that and if you're that unlucky one who wants to make games and not high speed quantum calculators or whatever, you literally have no content...

Hello Gustavo, are you planning to make some videos or courses explaining how to graph complex shapes such as spheres, toruos, and other surfaces of revolution in 3D, I was watching the one about triangles, and it is the best I have seen and in a way that is understandable. very good, and I would like to know how those figures are generated and how 3D software works. Thank you very much in advance. Greetings.

Amazing video , very suitable for this minimalist programmer and developer 😊 are you also going to share some idea about building an emulator too?

thank you for this video.

Wow❤

thanks for the video, now i want to code games 💫💫💫
