This video has few years worth of knowledge regarding computer graphic's practices and techniques, compressed into 33 minutes. It's definitely one of the most valuable stuff I watched on TH-cam ever.
Great video! I would absolutely love an OpenGL turorial style series as you mentioned at the end of the video - not just for learning practical opengl but also about how it works behind the scenes in more detail (such as the pipeline, contexts VBO VAO explanations you gave) and in general about the mathematical aspects of computer graphics (such as the linear algebra stuff, the lighting and shading alogrithms). Honestly just you mentioning these stuff briefly always gets me to pause the video and google them immediately.. takes me a couple of hours to finish your videos but I'm learning a bunch lol. Anyways these videos are GOLD thank you!
Great video! Just a small correction: OpenGL is not right-handed nor left-handed at the geometry phase, it is only left-handed after rasterization, much like DirectX and all other graphics APIs. What determines what handedness is assumed, is how the projection matrix is generated. In this case, it uses GLM's function, which includes the Z-flip in the matrix it produces - this is what makes this assumption about the source vertex data being structured with a right-handed coordinate system. If you flip that z-negation back in the projection matrix that GLM perspective yields (or just construct it manually yourself) you can then use a left-handed coordinate system for your vertex data. OpenGL has no say in the matter, it is you that is multiplying your vertex data with that matrix that you yourself are also providing - all in your vertex shader. The only real requirement is that the output of the vertex shader's vertex positions are all left-handed. GLM just followed the very legacy 'convention' of 'assuming' that the incoming vertex data is right-handed, and so includes that z-flip in the perspective projection matrix that it's function produces. That's where that assumption is made, not in OpenGL itself. Way back, when OpenGL had it's own built-in perspective projection, it really was the case that you could say 'OpenGL is right-handed' (sorta..), but once it started requiering vertex shaders, that stopped being the case - and that's already decades ago.

Cool author. Cool lesson. There is very little open information on this issue. Thank you for your work. I would be glad if you continue to release something further on this topic.
This is perfect, it's fast and not a lot is explained which is good, cause you'd expect the person to have some opengl knowledge to go as far as to 3D. Yet python also makes this very easy, I'm so glad I found this video, I've been wanting to make stuff like this
Hi. In the Transformation section of the video; in the 'get_model_matrix()' function, the 'self.pos' parameter in 'm_model = glm.translate(m_model, self.pos)' is marked as an unexpected argument by Pycharm and only a single cube is showing. What could be causing this?

Hi! I have followed your tutorial in order to create a 3D engine and I have been trying to implement a terrain instead of the boxes.

Would be really helpful :)
hello, i have problems with the glm-module. for some reason it is marked as malware by my anti virus program. So i cant compile the code, simply because it cant import the glm-module. What am i supposed to do?
Thank you very much for this great tutorial! Exactly what I was looking for. I am new to PyCharm and was wondering how/which color scheme you used to make your python code look so tidy? Greetz
if i want to animate a 3d model, would the engine be powerful enough for a naive approach where i just have a sequence of obj files for the animation and load them in fast ? or is there a better way? awsome video btw
Best tutorial I have seen. A lot of information that you need to come back several times. While the code was written in front of me, I made several mistakes (colon rather than semicolon, typo ..etc).. I learned also that doing mistakes in the shader is not easy to debug. As a beginner in OpenGL I see this tutorial great. Can I ask what text-to-speach program you use please? Thank you very much for the time you put to produce this great content.
Good afternoon. Please tell me how to find in your application what vertices it has in an object. That is, where is the vertex array located and how to view it. Thanks in advance)
Cool tutorial, but I must say I'm quite unhappy with the performance; it runs like an absolute dog on my 2019 iMac with 3.6GHz i9 and 580X Radio Pro. Obviously the hardware is not weak for a scene like this, what is the primary bottleneck?
Great tutorial! I'm fairly new to programming. I've implemented color picking to this so far and have been stuck on trying to understand how to move the cat individually. Reassigning the position does not work, but would be optimal. I'm wondering if it's possible, or there is a better way?
I still get those irritating white lines after applying mipmaps and the isotropic filter. Any clue as to why? The mipmap made it a little better but they are still clear as day.
This tutorial is amazing, but I'm getting stuck at 6:52. When I try to run the program at that point it says "FileNotFoundError: [Errno 2] No such file or directory: 'shaders/default.vert'" even though the file exists and is in the right spot in the folder. I checked and there are no typos. I don't know what happened.
Ok. I think I found the issue. I needed to have only the folder for the 3D engine open. If I have another directory open with that folder inside, it doesn't work. Thanks!
All very cool and a much easier approach than I was taking. However, what would I have to do if I wanted to render a cube with 6 different textures or colours. Like a rubix cube. Would I have to split the cube into their own surfaces (6 cubes with thin walls) or is there a better/different way. I don't really want to split the cube in 6 since that will mean that if I wanted to move the cube I would have to move each instead of moving the whole cube.
Hmmm, Why do I have the background color but not the rest ? I verified my code and the only potential problem that I can see is that I cant use version 330 OpenGl So I use version 310 in the GraphicsEngine class context but It still works if i set the version to 330 in the shaders
Thank you for this video, I learned a lot by playing with the code and I was able to create projects that I wanted to achieve. But I'd need some advice. I'm creating a physics engine and i'm struggling a lot with the spherical shapes like the icosphere or cylinders. I have written several scripts but none of them work. How would you proceed, in the way of this tutorial, to render sphericals object ? I had a great time watching all your videos. Thank you for all of them they are really usefull.

If you define a texture with internal GL_SRGB8 format then you can get hardware auto conversion from sRGB to linear space and don't need power function in a fragment shader. I really don't know if this is possible in Moderngl? The last conversion (pow(1/gamma)) could be also avoided if Pygame supports creation of SRGB framebuffer. For example in FreeGLUT you can create window with GL_SRGB flag, and then call glEnable(GL_FRAMEBUFFER_SRGB) to get final auto conversion from linear to sRGB space for free. There is a good reason to have nonlinear displays and cameras. If you transfer pictures through medium (cable, air, etc.) you will always get extra noise attached to your signal. Our eyes have logarithmic response and are oversensitive to dark colours so noise is much more visible when light is very weak (dark faces, shadows, etc.). Pictures with nonuniform "noise damage" (perceptually concentrated in dark regions) looks bad so EE engineers designed cameras with x^(1/2.2) transfer function to boost dark colours that can survive noise attack during travel through space. Displays inverse that with x^2.2 function to bring back original relationship between colours. In the end noise is still on the picture but perceptually is spread across whole picture and final result is much more pleasant to human eyes, and they are wiling to pay money for such designed nonlinear systems. In digital systems 8-bit light intensity values are considered noisy and "bands" (quantization noise) are visible in dark colours just like in old analog systems. You need at least 12-bit for each red, green and blue value to have perfect picture without visible artefacts. But we like 8-bit because it's cheap, less bytes to transfer so it's fast, it also takes less space on SSDs. Because of that, we have nonlinear cameras and displays with gamma=2.2 just like in old analog systems.
bro i got a problem, in my model.py file i have right all code correct but it's give me an error, the error is such a file or directory not found: shaders/{shader_name}.vert, help plz
but pygame supports many functionalities, eg this code snippet def surf_to_texture(app, surf): tex = app.ctx.texture(surf.get_size(), 4) tex.filter = (moderngl.NEAREST, moderngl.NEAREST) tex.swizzle = 'BGRA' tex.write(surf.get_view('1')) return tex converts a pygame surface to a sampler2D texture to allow for 2d games in 3d ones, and its far simplet to use
HI! im new to OpenGL and pygame, but at 5:01 i keep getting an error, i have tried downloading the code, still dosnt work. this is what dosnt work "program = self.ctx.program(vertex_shader=vertex_shader, fragment_shader=fragment_shader)" im not sure why... sorry for disturbing you Edit: OMG I GOT IT WORKING THANK YOU X
I don't know if anyone else is having this problem, but when I tried to add multiple cubes to the scene (after following the video to completion), I only ever saw the last cube added to the list of objects in the scene class.
Interestingly, apparently it's a long-standing pygame bug for some PCs that you can't have BOTH event.set_grab True and mouse.set_visible True without things going haywire in a non-fullscreen window. So if anyone else has unexpected issues at that part (around 18:00) just comment out setting the mouse invisible.

bro i got a problem, in my model.py file i have right all code correct but it's give me an error, the error is such a file or directory not found: shaders/{shader_name}.vert, help plz
I'm facing the same problem
but my mistake was that the shader files were not in the shaders file/directory
it's simple
@@Kantdhx Bro thanks for help🙂
please, bro =) 😉
I'm getting an error saying "Triangle() takes no arguments"
I recommend using GLFW instead of Pygame and also give use to Index Buffers, othervise, good watch!
but pygame supports many functionalities, eg this code snippet
def surf_to_texture(app, surf):
tex = app.ctx.texture(surf.get_size(), 4)
tex.filter = (moderngl.NEAREST, moderngl.NEAREST)
tex.swizzle = 'BGRA'
tex.write(surf.get_view('1'))
return tex
converts a pygame surface to a sampler2D texture to allow for 2d games in 3d ones, and its far simplet to use
Can you make a tutorial for how to make a 3D engine using vulkan
You should talk in videos, it would feel more natural and engaging, luv your videos btw 👍
you are the best dude
Very helpful..thanks a lot.
What is the algorithm of this project? Sir
Hello. Your videos are awesome! Can you tell which pycharm theme you use? Its elegant!
Color scheme: Monokai
@@CoderSpaceChannel Thank you so much
Super Nice - instant abo
8:50 Error: module glm has not attribute perspective
Same here 😔
how to make each surface of the cube have a different texture
what would be the path to take to make an android apk?
any ideas on how to implement billboards ?
HI! im new to OpenGL and pygame, but at 5:01 i keep getting an error, i have tried downloading the code, still dosnt work. this is what dosnt work "program = self.ctx.program(vertex_shader=vertex_shader, fragment_shader=fragment_shader)" im not sure why... sorry for disturbing you
Edit: OMG I GOT IT WORKING THANK YOU X
I don't know if anyone else is having this problem, but when I tried to add multiple cubes to the scene (after following the video to completion), I only ever saw the last cube added to the list of objects in the scene class.
me too.
Absolutely!!
Welcome back.
Finally, a new video.
At 8:30 it says that glm has no attribute perspective?
check that you have installed the correct glm:
pip install PyGLM
@@CoderSpaceChannel İ did that too, doing it again now it says requirements already satisfied
you can email me
@@CoderSpaceChannel what's your email?
email in the section - about the channel
Interestingly, apparently it's a long-standing pygame bug for some PCs that you can't have BOTH event.set_grab True and mouse.set_visible True without things going haywire in a non-fullscreen window. So if anyone else has unexpected issues at that part (around 18:00) just comment out setting the mouse invisible.
Why is it between -89 and 89?
Does it co with the samples?
Yes, sure
