RayTracing – Implementing the Raytracing Algorithm

https://www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-ray-tracing/implementing-the-raytracing-algorithm     We have covered everything there is to say! We are now prepared to write our first ray-tracer. You should now be able to guess how the ray-tracing algorithm works.【我们开始来实现算法】     First of all, take a moment to notice that the propagation of light in nature is just a countless number of

RayTracing – Raytracing Algorithm in a Nutshell

https://www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-ray-tracing/raytracing-algorithm-in-a-nutshell     The phenomena described by Ibn al-Haytham explains why we see objects. Two interesting remarks can be made based on his observations: firstly, without light we cannot see anything and secondly, without objects in our environment, we cannot see light. If we were to travel in intergalactic space, that is what would typically

RayTracing – How Does It Work?

https://www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-ray-tracing/how-does-it-work     To begin this lesson, we will explain how a three-dimensional scene is made into a viewable two-dimensional image. Once we understand that process and what it involves, we will be able to utilize a computer to simulate an “artificial” image by similar methods. We like to think of this section as the
