Understanding Ray Tracing: A Quick Overview

To appreciate and analyze the impact of ray tracing on FPS, it is vital to first understand what ray tracing is.

What is Ray Tracing?

Ray tracing is a rendering technique that simulates the way light interacts with objects in a virtual environment. Unlike traditional rasterization, which creates images by projecting 3D scenes onto a 2D plane, ray tracing traces the pathways of individual rays of light as they bounce off surfaces. This method captures complex phenomena such as reflections, refractions, and shadows, rendering images that are significantly more realistic.

How Does Ray Tracing Work?

Ray tracing uses algorithms to calculate light paths in a scene. Here’s a simplified explanation:

  1. Rays are Originated: The process begins at the camera, where rays are launched into the scene.
  2. Intersection Tests: For each ray, the rendering engine checks for intersections with objects in the 3D space.
  3. Determining Lighting: Upon finding an intersection, the system calculates the color and brightness at that point using lighting models, taking into account the position of light sources, shadows, and other visual elements.
  4. Recursion for Effects: Ray tracing can also handle reflections and refractions by creating new rays that emerge from the initial intersection point, allowing for effects like transparency and glass reflections.
