What are the basics of ray tracing in C++?

What are the basics of ray tracing in C++?

Ray tracing is a rendering technique that simulates the way light interacts with objects. In C++, it involves calculating the paths of rays as they travel through a scene.

How do I set up a simple ray tracing project in C++?

To set up a simple ray tracing project, you'll need a C++ compiler, a basic understanding of 3D graphics, and libraries like OpenGL or SDL for rendering.

Can you explain how to implement shadows in ray tracing?

To implement shadows, you can trace rays from the point of intersection to the light source. If the ray hits an object before reaching the light, that point is in shadow.

What are some common optimizations for ray tracing?

Common optimizations include bounding volume hierarchies (BVH), spatial partitioning, and using multi-threading to speed up ray calculations.
