What are fragment shaders in C++ graphics programming?

Fragment shaders are programs that compute the color and other attributes of each pixel in a rendered image.

How do I write a simple fragment shader?

To write a simple fragment shader, you need to define the main function and specify the output color. Here's a basic example:

#version 330 core
out vec4 FragColor;

void main() {
    FragColor = vec4(1.0, 0.0, 0.0, 1.0); // Red color
}

What tools do I need to compile and run fragment shaders?

You typically need a graphics API like OpenGL, a shader compiler, and a rendering context to run fragment shaders.

Can you explain how fragment shaders work with vertex shaders?

Fragment shaders work in conjunction with vertex shaders; the vertex shader processes vertex data, while the fragment shader handles pixel data after rasterization.
