What is ray tracing in C++?

What is ray tracing in C++?

Ray tracing is a rendering technique used to simulate realistic lighting by tracing rays of light as they interact with objects.

How does ray tracing differ from rasterization?

Ray tracing calculates color based on light interactions, while rasterization converts 3D models to 2D images without simulating light.

Can you give me a simple example of ray tracing code in C++?

Sure! Here's a basic example:

#include <iostream>

int main() {
    // Simple ray tracing logic here
    std::cout << "Ray tracing example";
    return 0;
}

This is just a placeholder; a full implementation would be more complex.

What libraries can I use for ray tracing in C++?

You can use libraries like OpenGL, DirectX, or even dedicated ray tracing libraries like OptiX or Embree.

What are the performance considerations for ray tracing?

Ray tracing is computationally intensive, so optimizing algorithms and using acceleration structures like BVH can help improve performance.
