[GLSL] Fragment Coordinate (gl_FragCoord) https://thebookofshaders.com/03/ The Book of Shaders Gentle step-by-step guide through the abstract and complex universe of Fragment Shaders. thebookofshaders.com In the same way GLSL gives us a default output, vec4 gl_FragColor, it also gives us a default input, vec4 gl_FragCoord, which holds the screen coordinates of the pixel or screen fragment that the active thread is working on. With vec4 .. 2022. 1. 5.

[GLSL] What is a shader? https://thebookofshaders.com/01/ The Book of Shaders Gentle step-by-step guide through the abstract and complex universe of Fragment Shaders. thebookofshaders.com Shaders are also a set of instructions, but the instructions are executed all at once for every single pixel on the screen. That means the code you write has to behave differently depending on the position of the pixel on the screen. L.. 2022. 1. 5.
[GLSL] Let's Dive in to the Shader! I wanted to study graphics languages (especially shaders), but I was worried about which language to choose between OpenGL and DirectX. I am currently using a MacBook and would like to use an online tutorial which name is "The Book of Shaders". Furthermore, in fact, GLSL and HLSL are similar to each other except for a few syntax... so I finally decided to study OpenGL shaders. As I mentioned, I .. 2022. 1. 5.
