What are ray tracing lighting models in C++?

What are ray tracing lighting models in C++?

Ray tracing lighting models simulate how light interacts with surfaces in a 3D environment using C++. They calculate reflections, refractions, and shadows to create realistic images.

Can you explain the difference between ray casting and ray tracing?

Ray casting is a simpler technique that determines visibility by casting rays from the camera to objects, while ray tracing simulates light behavior more accurately, including effects like shadows and reflections.

What are some common algorithms used in ray tracing?

Common algorithms include Whitted-style ray tracing, which handles reflections and refractions, and Monte Carlo ray tracing, which uses random sampling for global illumination.

How can I implement a basic ray tracing model in C++?

To implement a basic ray tracing model in C++, start by defining your scene with objects, then create a ray class, and finally, write a loop to trace rays from the camera and calculate color based on intersections.
