    Just a little correction, OpenGL doesn't handle your input, that's GLFW, which is the framework that creates the OpenGL context and Window, OpenGL is just for rendering. Awesome stuff though

    Sets up OpenGL for communication with GPU, proceeds to do all pixel calculations on the CPU and use the GPU as a pass through.
    Jokes aside, nice work 👍 I think its really creative to use the texture buffer like this and given that its low rez the performance isn't really needed anyway.

    • @nofalldamage
      @nofalldamage 10 місяців тому +2

      Normally, the GPU receives an input like triangles of a mesh and produce pixel colors from that. That is a lot of work depending on how complicated the mesh is. In this case the GPU is given a texture with all colors already set. The only thing the GPU has to do is pass it on to the screen. This is a whaste of the GPUs power but given the pixel nature of the engine I don't think that power is needed yet.

    there are lots of good reasons for making your own engine.
    - for fun
    - avoiding bloat
    - making it only have what you need
    - performance
    - having it support niece features you want
    - it is your own (you won't have to pay anyone else for using it, since it is your own)
    - getting better at programming (when you use something like unity you learn how to make something using unity, but when you make a game engine you begin to learn how to make a game by yourself, so you get better at programming, and in case unity ever goes away, you can continue making games without it)
    and more that I don't remember atm.

    This is neat, and a good learning experience for sure. I've been doodling with Vulkan for a few years now. It's really REALLY good, but it's also a ton of work.

    @samuelyigzaw Рік тому +4

    Whoaaa, this video has so many coincidences with me it's crazy. Everything from your thought process choosing learning OpenGL, the tutorial you used, the idea for a game engine that would run in the shader code instead of in the cpu code. All the same. My idea was inspired by Noita, trying to see if a game like it could be optimized further by runing it's pixel simulations on the gpu. It might be use a cellular automaton to define the physics too, and the double buffering in the rendering pipeline is also coincidentally necessary for the cellular automaton to be stable. It was so perfect. But I never got past the point where you ended, i.e. the texture page. I know that's probably all I need, but now I'm procrastinating haha. Maybe your project will give me the push I need.

    this architecture isn’t actually all that bad. It’s a common technique called Software Rendering. Although the converting it into texture isn’t the most common thing. You could of also used SDL2 which would of also let you convert a pixel array into a texture and then render it with the GPU but just with a fair simpler API.

The performance you get is almost entirely dependent on your engine design/subsystems, draw call optimizations, etc.

      Glfw is the library/api to create windows and create OpenGL contexts in those windows ,by default glfw imports OpenGL(or Vulkan if #define GLFW_INCLUDE_VULKAN is written in the file) which means he did indeed have to use OpenGL, just because there isn't any shaders or anything doesn't mean he didn't use OpenGL,He. literally talked about an OpenGL FUNCTION he used. So why do you Mr. Zuckerberg feel the need to chime in on his work even though you most likely have never written a single c library in your life. What has he done to you to make you angry? Do something different than usual?

    That pixelndex calculation is wrong and works only because you have square window. It should be:
    ((y * windowWidth) + x) * 3
    also the bounds checking should not allow x or y to be the width or height respectively.

      C++ is very performant and has some useful abstractions over C or assembly like OOP which becomes very handy for Engine Development later on. But it's a memory unsafe language so you should use rust btw.

      Kind of a weird and loaded question to ask, considering most game engines are made in C++, literally every major game engine is written in C++ (Unity, Unreal, Godot, etc). What was he gonna write it in, Python? Sure, if you want very weak performance, by all means. But you're not gonna get hundreds or even thousands of frames per second like you can with C++. It's a compiled language and creates a native binary executable for the system it's on. Really the only logical option.

    Well, your video is already quite old, so maybe you already figured these things out by yourself, but it looks like you don't quite understand the purpose of OpenGL.
    You're not supposed to send an array of pixels as a texture and have it render there. The whole point of OpenGL is that you send to it primitive shapes and then it figures out by itself how the pixels should be. It can do this much faster than CPU code, because it runs on the graphics card.
    If you already know how the pixels should be, then you did all the rendering in the CPU, and you don't need OpenGL.
    What you're doing is rendering everything in the CPU, sending all the stuff to the graphics card, which puts them on the screen without doing anything.
    It would be more straightforward, faster, and give you code with less dependencies if you just opened a pixmap to your OS display server and transfered the pixels there. In Linux Xlib does this, I don't know about Windows, but pretty much any GUI toolkit should have a way to open a pixmap.
