Where do we write our code? What does the code look like?
I go through the basics of our GLSL editor in this video.

This series is based off of the free on-line book, "The Book Of Shaders", by Patricio Gonzalez Vivo and Jen Lowe.

when i searched "opengl fragment shader" on youtube, the next video in this series was the top result. I went back one video to this one for more context.

Hello, I found your video after searching for 'shadertoy tutorial' then clicking on a video titled OpenGl Shaders and your video was in the recommendations buried around 12 deep.

These are simply amazing tutorials. With respect to everybody else, many video are claiming to teach what shaders are, however, they almost all end up showing how to code, omitting the finer details.

You have explained what the shaders are in relation to the gpu The visualization of the plane and explanation of a pixel asking what colour am I? Made me understand shaders for the first time.

Thank you very much

RGB(1, 0, 1) is called magenta, not "pink." It's the opposite of green color. CMYK(0, 1, 0, 0) is not green but magenta. RGB and CMYK are opposite systems, RGB for color addition and CMYK for color subtracting (printing).
