  1. To learn open gl you need to learn how the c/c++ compiler works, how the memory works, pointer arithmetics, glsl – shader language, creating window (be it a native api or glut or glfw) then math and a lot of stuff that would melt your brain.

  2. It's like copy pasting from stack overflow, no-one really understands what the code is doing.

  3. So now we know how to make a reandering engine for our game engine that will make gta vc

    :))

  4. I don't know if anyone can help me but when trying to add color to each specific vertex my vertices themselves get thrown into different places than charted originally and they do no get colored. I am referring to what he tries to show us at 38:33, and how it colors the three triangles with the gradient. I had the triangles showing up fine before, then once I went through this section it disfigured the triangles and then proceeded to not color them.

  5. why there's no windows popping out when I try this?

  6. My triangle is white in color while his what orange. I have rechecked my code but still havent found any error can someone help me?

  7. Why are we using the OpenGL 3.3 only? Since there are more recent versions shouldnt we use the most recent?

  8. 比我们老师讲的好多了呜呜呜,感谢您

  9. We now have a nicely colored window that you can show off to your imaginary friends.

    aw, thanks

  10. OpenGL真的对游戏开发很重要。

  11. This is why I dislike C and C++. Such a pain in the ass to import libraries.

  12. Im looking to create a game as a independent developer. A 3D platformer adventure

  13. this is crazy high quality like I'm actually able to follow along with almost no problems so far

  14. after 03:09 i get an error in cmake "Error in configuring process, project files may be invalid". What do i do then?

  15. imma be real the first 8 seconds sounds very odd

  16. I built without errors but when I ran it it shows only the black command prompt box with cursor blinking like it is waiting for me to type something, when I typed something there was no reaction.

  17. any way we can get a video of others 3d shapes?

  18. Very cool. I think the comments are useless, though. They just state exactly the code below it, so there's no point in having it.

  19. I'm not CS student, but i'm interested with computer graphics after watch this video, thanks

  20. holy crap man slow down I need a chance to pause the video to type this stuff. jeez

  21. 13:50 "We now have a nicely colored window to show off to your imaginary friends"

    It may be true but it still hurts 🥲

  22. GPU จะประมวลผลก็ต่อเมื่อ​ code​ มี​ HEADER​ GPU​ เช่น​ FX, ดีกราฟ

  23. I dont think i have seen a single youtube video which has zero disllike …
    this one has 380K+ views 11K likes no dislikes .. nicee

  24. Why are you racing through everything, how do you expect me to replicate your actions without setting the playback speed to 0.25

  25. it didn't work when i tried to keep the window open after the part where he says that if you don't you will see a window for a split second and it dissapears it said no errors but then i ran it and it said i had a break point

  26. Great Course! But its too fast paced for me.

  27. I don`t understand how to import .stl file format instead of .gltf. How can I do this? Can somebody try to expalin?(

  28. Hey everyone, I hope you've enjoyed the course I've made, had a lot of fun making it! 🙂
