Procedural 3D Engine. Ray Marching OpenGL Tutorial

Python OpenGL Tutorial on creating Procedural 3D Graphics Engine using the Ray Marching technique. To work with OpenGL, the Python language and the ModernGL module will be used, and all the main work will take place in a Fragment Shader in GLSL

Project code:

I have been blown away by how well done and cool these little projects are. Nice stuff

[luki]

Really impresive video, you deserve much more views

[unmodify]

Brilliant! Loved the structure of the. Nice how you added things in one at a time. Goes a long way explaining the same named concepts. Would love to see more of the world of shaders like this.

[miumenk]

Very powerful vids, keep the great work!

[willw]

Wow. This video packed so much information in one shot. Truly impressive.

[tonnysocrates]

I just love it even though I understand 2% of the content. Keep the content coming, I'm trapped into this

[yangdeveloper]

wow I stumble across your channel by accident. Instant Sub.

[theattic]

How would you implement keyboard movement, sort of like a FPS.

[blindne]

What text2speech engine are you using? Love the video btw!!

[MrMagno-nilf]

Can you please tell what FOV is measured in?

[marcosdanieltorres]

Great video! I have a question though: at 2:40 why are you not substracting ro from rd? Like this:
vec3 rd = normalize(vec3(uv, FOV) - ro) This is confusing me a lot. What is the actual difference between rd vs rd - ro in this case?

[khatriiman_b]

float d = rayMarch(p + N * 0.02, normalize(lightPos)).x;
if (d < length(lightPos - p)) return vec3(0);
return diffuse;

i have same code as you still this part is not working can you help me with this??

[sivaramakrishnanr.]

I'll return here the day i understand ALL this stuff

[XENON]

hey, I know this is old but do you know why I am not getting any shadows (I am at 8:24)

[warrior]

Did you write these codes by yourself? I'm impressed, you must be some genius....

[dimitrisgkofas]

how many functions does the shader can handle with 60 fps ?

[whupass]

Wow, I am truly impressed. How did you learn about Ray Marching?

[docname]

Слушай, я тут просто нашел канал который ты скорее всего переводишь
Надеюсь, это вы договорились

[BaguetteDeP]

I cloned your repository but can't make it to work... 😢
i got :

GLSL Compiler failed

fragment_shader

ERROR: 0:728: 'pMod1' : no matching overloaded function found (using implicit conversion)
ERROR: 0:728: 'pMod1' : function is not known

Inspirational video, though not very useful unfortunately - more of a brief exposition to the topic than a tutorial, so the most that newcomers could hope to come out of watching it with, is being able to make some nice tasty code copy-pasta ;)
Each of about a dosent theoretical nuggets here can easilly fill a whole tutorial unto themselves to really cover properly and provide a concrete grasp of how things work. Would be great if that could happen as a series of follow-ups! :)

More specifically, while the video includes a combination of rough coverage interwoven with code-snippets, there's very little to tie them together. So the video comes across as: "hey, look at all those cool stuff I can do! (and maybe you could too, if you spend some weeks/months learning them elsewhere...)"
