What is real-time ray tracing in C++?

What is real-time ray tracing in C++?

Real-time ray tracing is a rendering technique that simulates the way light interacts with objects to create realistic images. In C++, it involves using algorithms to calculate light paths and render scenes dynamically.

How does it differ from traditional rasterization?

Unlike rasterization, which approximates lighting and shading, ray tracing traces the path of rays of light to produce more accurate reflections, refractions, and shadows, resulting in higher visual fidelity.

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

You can use libraries like NVIDIA's OptiX, Intel's Embree, or open-source options like PBRT and Raylib for implementing ray tracing in C++.

Is real-time ray tracing performance-intensive?

Yes, real-time ray tracing is computationally intensive, but advancements in hardware, like RTX GPUs, have made it more feasible for real-time applications.
