Tutorial 9 - Coordinate Systems in OpenGL

This tutorial describes the different coordinate systems that are commonly used when creating OpenGL programs. It's important, so watch it!

This is the best OpenGL tutorial I have ever seen.

This is the best introductory tutorial for OpenGL. Can't believe others couldnt elaborate it that easily.

I have seen many tutorials on this subject but, this one is the most clean explanation among them. You deserve more attention. Bravo.

Amazing. Describes the most important concepts in a graphics class in 7 minutes rather than several hours of lectures.

This is the best tutorial for learning openGL even I am now study this in 2021. Thanks a lot Jeffry

Clean, clear, and really gives understanding. 10/10, especially considering the time you did it in.

omg i love you, this is the intro i needed into this topic

[gilbertnordhammar]

After seeing this tutorial, it seriously frustrates me why most other tutorials don't explain this subject as clearly. In other words, really nice tutorial!

In reality what happens with the projection matrix is to transform coordinates to clip space, then from that they will be diveded to w to get to the NDC system. After having had NDC, there is even one more transformation to screen space, and that is when fragment shader start to execute.

Your videos are real good, keep up the good work.

You're awesome you compressed a long text tutorial into 7min video!

[vikramadityakukreja]

Seriously a very good tutorial ! Will watch your other vids as well. Thanks!

I think we forgot to talk about the screen matrix...that projection matrix eventually has to end up on the screen. Seems we need another matrix to change projection to actual screen pixels.

Very well made tutorials! You should make tutorials on the recent Vulkan API as well.

Great tutorial, it helped a lot, thank you

I get that the camera never moves in the camera space, but the camera has a world space position, so does the camera actually move within world space?
