C++ Ray Tracing vs Path Tracing

What is the difference between ray tracing and path tracing in C++?

Ray tracing simulates rays from the camera to the scene, while path tracing simulates light paths from the light source.

Which one is more efficient for real-time rendering?

Ray tracing is generally more efficient for real-time rendering, but path tracing produces more realistic results.

Can you give me an example of how to implement ray tracing in C++?

Sure! You can start by creating a simple ray class and a scene with basic shapes like spheres and planes.

What are the advantages of using path tracing over ray tracing?

Path tracing handles complex lighting scenarios better, including caustics and global illumination, resulting in more realistic images.
