1、 总起 光线追踪(Ray Tracing)是一种逐像素的渲染方法,相比使用z-buffer缓冲算法的光栅化渲染模型,光线追踪因为使用求解方程的方式来检测相交表面,所以在计算阴影和反射上更加简单有效。虽然光线追踪真实性优于光栅化,但计算量却非常大,一般只能离线渲染。 而路径追踪是光线追踪的一种,在求交方面和传统Whitted-Sty...
本次作业的内容是对上一次作业中的BVH遍历、射线三角形求交Möller-Trumbore算法进行迁移,以及在此基础上实现完整的 Path Tracing 算法。 请注意: 本次作业基于dalao的GAMES101作业框架,在Windows系统上实现。 函数迁移 Bounds3::IntersectP in Bounds3.hpp 本次作业中 cornell box 模型的墙壁和箱子某些三角形是平...
games101 作业7 实现path tracing 好家伙,闫老师说此程序很慢,算是见识到了path tracing有多慢。。。(渲染时间1个小时) 这是3月3号了,主要是2月份过年,然后其他东西,本来我也懒,所以很多时候也荒废掉了,今天算是重新复习了一下渲染管线,然后,果然一段时间不写,框架全部忘光了。。。这个path-tracing也是理解一...

在之前的练习中,我们实现了Whitted-Style Ray Tracing 算法,并且用BVH等加速结构对于求交过程进行了加速。 在本次实验中,我们将在上一次实验的基础上实现完整的Path Tracing 算法。 至此,我们已经来到了光线追踪版块的最后一节内容。请认真阅读本文档,按照本文档指示的流程完成本次实验。

And I hope that in the future I will be able to buy any GPU made by Intel in every big shop in my country like I can get every Intel CPU now.And once again thank you kindly Hugo for you outstanding support! And for your understanding and patience!Best wishes to you and the support...
The PSR/CSFR combination described in this post solves many problems that arise during the development of a real-time path tracer: high-quality reflections and refractions with stochastic lighting, support for surfaces with ray-traced reflection and refraction at almost no additional cost, and sup...
