How can I implement advanced lighting in OpenGL using C++?

To implement advanced lighting in OpenGL, you can use techniques like Phong shading, normal mapping, and shadow mapping. Would you like to dive into one of these techniques?

Yes, can you explain Phong shading?

Phong shading is a technique that calculates the color of a pixel based on the light's position, the viewer's position, and the surface normal. It involves ambient, diffuse, and specular components. Would you like to see some code examples?

Absolutely! Can you provide a simple code snippet?

Sure! Here's a basic example of Phong shading in C++ with OpenGL:

// Vertex Shader
#version 330 core
layout(location = 0) in vec3 position;
layout(location = 1) in vec3 normal;

out vec3 fragPos;
out vec3 fragNormal;

uniform mat4 model;
uniform mat4 view;
uniform mat4 projection;

void main() {
    fragPos = vec3(model * vec4(position, 1.0));
    fragNormal = mat3(transpose(inverse(model))) * normal;
    gl_Position = projection * view * model * vec4(position, 1.0);
}

This is just the vertex shader part. Would you like to see the fragment shader as well?
