For those that do not know me: My name is Jacco Bikker, also known as 'Phantom'. I work as '3D tech guy' at Overloaded, a company that develops and distributes games for mobile phones. I specialize at 3D Symbian games, which require highly optimized fixed-point, non-HW-accelerated 3D engines, crammed into 250Kb installers. So basically I'm having fun. As software rendering used to be my spare time activity, I was looking for something else. I tried some AI, which was great fun, and recently I dove into a huge pile of research papers on raytracing and related topics; such as global illumination, image based lighting, photon maps and so on. One document especially grabbed my attention. It's titled: "State-of-the-Art in Interactive Ray Tracing", and was written by Wald & Slusallek. I highly recommend this paper. Basically, it summarizes recent efforts to improve the speed of raytracing, and adds a couple of tricks too. But it starts with a list of benefits of raytracing over rasterization-based algorithms. And one of those benefits is that when you go to extremes, raytracing is actually faster than rasterizing. And they prove it: Imagine a huge scene, consisting of, say, 50 million triangles. Toss it at a recent GeForce with enough memory to store all those triangles, and write down the frame rate. It will be in the vicinity of 2-5. If it isn't, double the triangle count. Now, raytrace the same scene. These guys report 8 frames per second on a dual PIII/800. Make that a quad PIII/800 and the speed doubles. Raytracing scales linearly with processing power, but only logarithmically with scene complexity. Now that I got your attention, I would like to move on to the intended contents of this crash course in raytracing.

opengl光线追踪算法实现原理与源代码演示 希望对大家有帮助

简单的光线追踪器 Rust 中的简单光线追踪项目，用于学习 Rust 并探索光线追踪的算法和数学。

用于从具有指定折射率的传播区域中的固定点发射一束光线的函数。 提供了带有示例的文档以说明无线电束在地球大气中的传播和传播。

Monte Carlo 技术是一种对光子在系统中的传播进行建模的统计方法。 随机数、累积分布函数 (CDF) 和概率密度函数 (PDFS) 用于从函数或光谱（例如太阳 AM 1.5）中进行采样。 通过这种方式，随机数决定了光子的命运，并且可以避免复杂的辐射传递方程。 记录每个表面发射的光子数量，这样就可以估计 LSC 的光学效率。
