This tutorial is an introduction to shader-based OpenGL

Someone who knows what their talking about ! Thanks alot.

This is one of the best tutorials for vertex and fragment shaders

Great video, I really appreciate you creating and uploading this! There are many tutorials or videos, that just go straight in with an example that are created in the sort of: "Then type this, and then this, and once you've done that, type this" format. These tutorials will get you a triangle sure, but they don't get anywhere really close to getting people the knowledge and basic understanding needed to be able to work freely with this code, and create anything you want from it. This tutorial is different, in that you've explained why and when things are used, but this can be applied to anything and you don't talk about something specific that you are creating. I like this! Thanks again, have a good day.

Thank you for making this video.. im watching an OpenGL series right now and they totally skipped over doing a quick run-thru of how OpenGL works.. This video is of great help.

Dude I want you to know that for about 3 months I have been unable to get my OpenGL stuff to work, I had it working in 5 minutes following this series so far, your explanations are crystal clear and straight to the point. Thank you so much for making this series and I look forward to learning more :)

Clear concept explanation and high efficency!

Brilliant in clarity and delivery, I'll definitely check out your other videos. It almost seems to me as if a lot of OpenGL lessons are presented in a deliberately convoluted manner. Maybe this artificial entry barrier offers employment security, I don't know. I've even tried the oft recommended _OpenGL® Programming Guide, Version 4.3_ and it's filled with typos (English), very ugly C++ code and a generally chaotic progression of topics. I'm glad I didn't pay for it.

hope i can make more than one like keep going bro

Out of curiosity you stated you could set a shader to a specific model, but how does that work exactly? Just trying to understand how shaders work overall

[vertigo]

btw does glLinkProgram(<prog ID>) take in more than one param for prog ID? that is.. does it take in both shader IDs at once or do you call glLinkProgram each time for each shader being used with a different ID.

[srhalnon]

im pretty sure openGL does support quads. 
glBegin(GL_QUADS);

and than you just load in the verts.

Can you please share the link to the source code.

[Cihadyldz]

really hard to understand it is hard topic and he explains very fast

[SlashXel]

i ve been scripting in game maker and... i understood nothing :D
guess i have to watch it 10 more times
