Tutorial 3 - Introduction to OpenGL Shaders

[@bonbonpony]

This dude is not wasting our time. Big thumbs up!

[@markschumacher3157]

Someone who knows what their talking about ! Thanks alot.

[@tanuvishu]

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

[@rodrigoreichert5845]

Your videos are brilliant. I've been trying to get my head around modern opengl and these videos finally got me to understand it all. I've watched the Lynda's tutorial on opengl, read over various blogs and online tutorials, none really made sense, most of them regurgitated the same information, like reading a dictionary, and speed running through code without proper background. Thank you for taking the time to create and share these videos.

+Rodrigo Reichert Glad you liked them!

[@vertigo6982]

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.

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.

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 :)

[@jeffchastine3536]

and THAT is why I made them :) Glad it helped!

[@halabihazem]

Thanks for making this video. This is the best intro video I've found for OpenGL shaders.

[@spardaks]

Clear concept explanation and high efficency!

[@anthonysegers01]

Great Job! Your OGL presentations are PERFECT! Thank You!

[@BogusLarry]

Thanks for explaining it from the ground up man. Really helped me.

[@jeffchastine]

Glad it helped!

[@karolinr9]

I love the short and consise tutorial. Thank you :) Cleared things up!

[@hoomanseyfi1941]

Thank you. your explanation is so easy to understand and so helpful

[@christheother9088]

Top notch work. Thank you.

[@jeffchastine]

My pleasure!

[@xzibiting]

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

[@PraveenMax]

Good explanation of opengl shaders!

[@jeffchastine]

Glad it helped!

[@viratsingh5955]

Great intro, thank you very much!

[@jeffchastine]

My pleasure :)

[@vertigo6982]

btw does glLinkProgram() 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.

[@HiAdrian]

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.

[@jeffchastine]

Glad you enjoyed them!

[@oonmm]

I rite those book for living this is no good vido! I need make money is my life! Ples stop giveing this away for free!

[@monmomo04]

great tutorial

[@mejaimounir9922]

hope i can make more than one like keep going bro

[@MateusChagasSousa]

nice tutorial dude! Thank you

[@redstonechoi]

Awesome

[@amruthasrinivasan3754]

Can you please share the link to the source code.

[@srhalnon]

im pretty sure openGL does support quads. glBegin(GL_QUADS); and than you just load in the verts.

[@jeffchastine]

I know this is true in early versions of OpenGL, but I believe they did away with glBegin().

[@srhalnon]

hmmm. than i wonder what im using. it said 4.1 in the terminal when i checked earlier. i wasnt using shaders though. (figuring out that part now :p)

[@cousinskitchen2]

I thought openGL supports quads?

[@abderrahmanemihoub8484]

thanks bro

[@jeffchastine]

No problem, and hope it helped!

[@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
