Ray tracing is primarily a feature within 3D design software that simulates the path of light in a virtual world to calculate the color of each pixel in an image. By adding 3D textures and HDRI environment lighting to models or scenes, ray tracing can generate highly realistic and lifelike images. However, compared to traditional rendering methods, it may require more computational resources.
<img src="https://img.relebook.com/news/edit/2023-12-7/e0bd617f-d31d-4f23-af1c-3d3eb9fb3ff0.png!relebook-news-detail-p">
Traditional rendering techniques, such as scanline rendering or rasterization rendering, typically rely on simple lighting models like the Phong or Blinn-Phong models. These models only consider the impact of direct lighting and ignore complex optical phenomena such as indirect lighting, reflections, and refractions. While this approach can produce decent results in many cases, it cannot achieve the level of detail and realism that ray tracing can offer.
On the other hand, ray tracing tends to be slower when dealing with complex lighting scenarios because it needs to trace every ray of light from light sources to the camera and account for reflections and refractions on all objects in the scene. This can result in a significant computational load, especially in scenes with a large number of triangles and complex materials.
However, with advancements in hardware technology, particularly the improvement in GPU (Graphics Processing Unit) performance and the emergence of dedicated hardware acceleration units like the RT cores in NVIDIA RTX series graphics cards, ray tracing has seen a significant boost in speed. Real-time ray tracing has become possible, especially in specific applications like gaming and interactive visualization, thanks to these hardware acceleration features.
Ray tracing doesn't always speed up rendering, but in certain situations, especially when high levels of visual realism are required, it is worth using. With technological advancements, its speed is continually improving.
