Simple Renderer
おもに学習用にいろんなレンダリングアルゴリズムを実装しています。順次追加中。Githubで公開。 パストレのアルゴリズムとシーンのデータ構造はsmallptを参考にしました。ありがとうございます。 物理ベースレンダラ（パストレーシング）の解説・実装をeduptとして公開しました。 双方向パストレーシングの解説・実装をedubptとして公開しました。 以下のコードは全てMITライセンスの下に公開されます。(http://kagamin.net/hole/license.txt) また、コードの一部はsmallptを元にしており、その部分もMITライセンスの元に公開されます。(http://kagamin.net/hole/smallpt-license.txt) 結構昔に書いたので誤りも多分に含まれている可能性があります。気づいた人はどんどん教えてください。 パストレーシング simple-
Ray Tracey's blog
Quasi-random, more or less unbiased blog about real-time photorealistic GPU rendering Well this put a smile on my face. Nvidia just announced Racer RTX, a fully real-time raytraced minigame running on their Omniverse platform on a single RTX 4000. It looks quite a few steps up from Marbles RTX, which was already exceptional in itself. The lighting and shading quality is fairly unparalleled for a r
DevMaster.net - Raytracing: Theory & Implementation Part 1, Introduction
Hello and welcome to a new series of articles (or column, if you wish) on the topic of raytracing. 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, cramm
Path tracing a cornell box in Javascript
Last Saturday I have released my little javascript pathtracer that rendered a very simple scene. This time I want to show off some of the more advanced effects that can be simulated nicely using path tracing. I decided to set up a scene similar to the well known Cornell Box to demonstrate effects such as soft shadows, color bleeding, reflection, refraction and caustics. I did not include Depth of

Line counts disclude comments and blanks and lines with only single braces/parentheses. Speed measurements were done on a Core2-Duo Mac, using the roomfront (non-sun) model. They are just rough indications. ‘Paths’ actually also send a ‘shadow ray’ at each node – so twice the paths-per-second would give general basic ray-traces/intersections-per-second. C was faster than C++ probably mostly becaus
