  Ray Tracing은 빛의 물리적 행동을 시뮬레이션하는 그래픽 렌더링 방법입니다. 이 방법은 빛의 거리, 각도, 물체 등에 따라 표면의 밝기를 결정하는 모델을 사용합니다. 로컬 조명과 전역 조명, 난반사 반사, 거울 반사, 굴절 등의 다양한 광학 현상을 모사할 수 있습니다. 광선 추적 방식에는 전방 추적과 역방 추적이 있으며, 그림자와 조명 광선 등 다양한 메커니즘을 통해 실제와 유사한 결과를 생성할 수 있습니다.

  Ray tracing is a powerful rendering technique that has become increasingly important in the field of computer graphics and visual effects. It is a physically-based approach to simulating the behavior of light, which allows for the creation of highly realistic and visually stunning images. The key advantage of ray tracing is its ability to accurately model the complex interactions of light with different materials and surfaces, including reflection, refraction, and diffraction. This enables the creation of images with realistic lighting, shadows, and other visual effects that are difficult to achieve with traditional rasterization-based rendering techniques. One of the main challenges of ray tracing is the computational complexity involved in tracing the paths of millions of individual light rays through a scene. This has historically made ray tracing a computationally intensive process, requiring significant hardware resources and rendering times. However, with the continued advancements in hardware and software optimization, ray tracing is becoming more accessible and practical for a wider range of applications, including real-time rendering for video games and interactive visualizations. Overall, ray tracing is a powerful and versatile rendering technique that has the potential to revolutionize the way we create and experience digital content. As the technology continues to evolve and become more widely adopted, we can expect to see even more stunning and realistic visual experiences in the years to come.
