Java LWJGL/OpenGL Game Development Tutorial 2: Intro to OpenGL

In this video we talk about basic OpenGL concepts that will be used throughout the rest of the videos in this series

Thank you! I made a 3D renderer thing that did it pixel by pixel that was insanely slow. Also this is the first set of tutorials I've found where things are approached from a mathematical perspective. Excellent!

[MClightOfDay]

THE MATRIX! LOL. These videos are awesome. OpenGL never made sense till now.

[ConsistentImprovement]

I just about lost my shit laughing when you said "even if it is a really derpy one" because I was thinking the SAME thing. Thank you for your video, I learned a lot.

I don't know if you're still reading the comments, but I'll try. Thanks for explaining the M-P-T Matrix stuff that OpenGL is doing. So I just started studying, learned all the stuff about matrixes, and was like kinda' aware of what they're doing.
Then at 12:00 I was like "WTF THAT'S AWESOME"
Thank you, sir!! :D
And thanks for your awesome work with the tutorials!

benny i like how you try to explain everything so it sounds easy but sometimes you get a little carried away and it makes it more confusing

[Gammelgalten]

Hey man. Thanks for taking your time to make these videos. They are quite helpful, unlike most other videos!

[BlackJar]

A like isn't enough for this -- liked the video, liked the series, and then put in the ol' book marks!

Matrix math is faster because OpenGL is run on the GPU. The GPU can have more than 200 cores that are each not as good at the CPU at quickly going from random task to another quickly, but since there are 200 of them you can compute like 200 simpler things at a time. Really useful for graphics because graphics requires the same thing to be done to maybe millions of triangles.

i'm studying computer science at university and we've had to do maths as part of the course, i hated the vast majority of it but one of the few topics i persevered with was matrices. I was so glad when you mentioned it that i actually managed to get my head around it before! Never thought i'd be happy to hear or see matrices again but there we go lol.

[JanWischnat]

Good stuff! Thanks for taking the time to produce and share!

[MegaFartart]

Don't worry. We ALL suck at mouse drawing.

[WestOfAnOcean]

Thank you for an excellent video! *liked*

[sonickk]

Can someone help? At my school we haven't learned about Matrices yet! From what I've looked at on the internet, they seem like 2D arrays in C++. Is this correct?

[FrenzyFirenze]

Would be accurate to say that the projection matrix takes the data from the model matrix and applies it to the perspective of a camera, or in short, applies projective geometry calculations to it?

[IoanTrolul]

thechernoproject does things like this, but he has a challange: to almost not use any java libraries

[eshylavi]

try in the VM options:

only replace the path to your own natives path.

[RickyT]

You could have saved your self a lot of effort by making use of the word 'perspective'. Nice vid BTW, I think I'm going to follow your vids for starting out in OpenGL.

Well don't you have a coords sys in gamedev like: top left corner = 0|0 and bottom right = x|y? Like i did with: glOrtho(0, Display.getWidth(), Display.getHeight(), 0, -1, 1);

Exception in thread "main" no lwjgl in java.library.path
I keep getting this... It doesn't want to work. sad face...

[hrbharry]

Math confuses me when it gets to matrices
