What are vertex shaders?

What are vertex shaders?

Vertex shaders are programs that process vertex data in graphics rendering, transforming 3D coordinates into 2D screen space.

How do vertex shaders work in rendering?

They take vertex attributes like position, color, and texture coordinates, and apply transformations to prepare them for rasterization.

Can you give an example of a vertex shader code?

Sure! Here's a simple example:

#version 330 core
layout(location = 0) in vec3 position;

void main() {
    gl_Position = vec4(position, 1.0);
}

What is the difference between vertex shaders and fragment shaders?

Vertex shaders handle vertex processing, while fragment shaders deal with pixel data after rasterization, affecting color and texture.
