Ray Tracing

Ray tracing is a rendering technique used in computer graphics to simulate the way light interacts with objects in a virtual environment. It works by tracing the path of rays of light as they travel through a scene, accounting for various interactions such as reflection, refraction, and shadows.In ray tracing, rays are cast from the eye or camera position into the scene, and the algorithm determines what those rays intersect, including surfaces, lights, and other elements. This method allows for the creation of highly realistic images with complex lighting effects, such as accurate shadowing, color bleeding, and reflections that mimic real-world physics.Ray tracing can produce high-quality visual effects but is computationally intensive, often requiring significant processing power and time to render each frame, particularly in real-time applications like video games. As technology has advanced, techniques such as real-time ray tracing have emerged, allowing for faster rendering by utilizing powerful hardware like graphics processing units (GPUs). Overall, ray tracing is a fundamental technique for achieving photorealistic images in various fields, including film, video games, and architectural visualization.
