Real-Time Rendering Portal

This page is devoted to sites and tools we use on a continuing basis. They're personal picks, and reflect our own biases.

  1. Ke-Sen Huang's conference pages has links for papers from all the major computer graphics conferences and workshops. The pages by Tim Rowley are not available directly, but this archive contains them.
  2. Advances in Real-Time Rendering in 3D Graphics and Games, Introduction to Real-Time Ray Tracing, Open Problems in Real-Time Rendering, An Overview of Next-Generation Graphics APIs, and Stylized Rendering in Games SIGGRAPH course materials are hosted on our site.
  3. SIGGRAPH 2020 links, compiled by Stephen Hill. Also see link pages for SIGGRAPH 2019 links (and SIGGRAPH 2019 ray tracing links), SIGGRAPH 2018, SIGGRAPH 2017, SIGGRAPH 2016, SIGGRAPH 2015, SIGGRAPH 2014, SIGGRAPH 2013, SIGGRAPH 2012 and SIGGRAPH 2011.
  4. Game Developers Conference 2019 links, also 2018, 2017, 2016. There's none for 2015, but before then Javier "Jare" Arevalo collected GDC 2014, 2013, and 2012 presentations. Also see the GDC Vault.
  5. Graphics Programming weekly - Jendrik Illner summarizes graphics blog articles. Think of it as your one-stop blog.
  6. NVIDIA (and NVIDIA Research), AMD (plus GPUOpen), and Intel graphics developer sites - demos, code samples, white papers, etc. Other worthwhile code samples at Humus-3D.
  7. Min Chen's list of Computer Graphics Forum State-of-the-Art (STAR), survey, and review papers since 2010.
  8. The Journal of Computer Graphics Techniques - open access (free to all) and many articles include code samples.
  9. Journal of Graphics Tools (JGT) code repository.
  10. Graphics Gems Repository - contains the source code for many graphics algorithms. Search the contents by category, by author, or by book.
  11. Developer sites and mailing lists: is active, as is, Ogre Forums, less so, GD Algorithms archives dying out but searchable (subscribe), and FlipCode (old, closed, but some good things in the archives).
  12. Game company publication pages: alphabetically, and a few quite dated, but here goes. Frostbite, Guerrilla Games, Unreal Engine, Unity, Ready At Dawn, Tri-Ace, and Activision.
  13. Film company publication pages: Disney (Hyperion renderer specific) and Pixar.
  14. Commercial research lab pages: Microsoft Research Asia, Microsoft Research U.S., and Cesium (GIS).
  15. The Level Up Report by Mark DeLoura is a free weekly that provides pointers to all sorts of developments and resources for learning through games, coding, and making.
  16. Level 80 has a constant stream of information for game artists and content creators.
  17. Free (and good) books online
  18. Models: McGuire, Stanford, ORCA, Disney, Apple AR Quick Look, Bitterli, pbrt, Mitsuba, USC-HairSalon, TurboSquid, Free3D, CGTrader, Sketchfab, Google Poly, BEEPLE (C4D project files), more.
  19. ACM TOG's Software Tools and Resources page has much about both graphics software and where to get 3D models, BRDF data, etc.
  20. Graphics and Game Gems Database lets you search the various popular interactive graphics series, browse each book's article titles, and get bibtex entries. IntroGameDev and AI Wisdom are similar sites. They leave out a few newer (and older) books, but have the advantage of being able to browse by category.
  21. APIs:
  22. Paper Search:
  23. Education:
    • Interactive 3D Graphics is an interactive course (MOOC) by Eric using videos (with transcripts) alongside exercises and demos (using three.js) that run in your browser. Focus is on general principles, though specifics, such as shader programming, are also covered.
    • The Rendering Course from TU Wien is a free master's level video course on rendering. More information here.
    • Intro to Parallel Programming uses CUDA to teach about GPU parallel programming.
    • Shader School is highly recommended for learning GLSL; it has a nice way of teaching you step by step. Answers here, as (on the Mac, at least) the one flaw is that compiler errors are not shown.
    • three.js is a scene graph layer and much more atop WebGL. It makes adding 3D web content pretty easy - enjoy the demos on that page, or sample the examples (and even better, commented examples here).
    • Scratchapixel has a series of articles on the basics of computer graphics theory.
    • Shadertoy is unlikely to help you write shaders - I just wanted to sneak it in. Rather, enjoy the extreme shaders (using procedural geometry, ray casting, etc.) that others have written, right in your browser. New shaders every day.
  24. Game Developer Magazine - all issues available free for download.
  25. Gameconfs - game-related conferences.
  26. Geometric Tools - there are many different code snippets and tutorials here to do all sorts of graphics operations, with a focus on computational geometry and intersection methods.
  27. Virtual Terrain Project - a constantly-expanding repository of algorithms about and models of terrain, vegetation, natural phenomena, etc.
  28. Github and SourceForge are popular places to browse for free, open-source software applications.
  29. 3D Object Intersection Page - where to find articles and code on this topic.
  30. FAQ - ancient, not maintained, but still full of computational goodness.
  31. - with the death of "Game Developer", no new content here, but some great old articles are available.
  32. Eric Weisstein's World of Mathematics is an incredible (though often dense) resource for mathematical definitions.
  33. tracks what is currently used by their subscribers.
  34. Dead End Thrills makes some excellent renders of current games.
  35. Tech Power Up has an up-to-date summary of the clock speed, memory size, and other characteristics for every major consumer PC GPU. Tech ARP has similar GPU charts for workstations, PCs, and mobile devices. Hardware Info has an amazing GPU comparison app. Notebookcheck also compares mobile GPUs, with text reviews.
  36. ACM TOG's Research Resources page much of the same information as here, but with a wider scope.
  37. GPU Review Sites - these sites often have in-depth analysis of GPU features:
  38. Game Related - Metacritic or for meta-ratings, VG Chartz for console and handheld sales figures, gamedevmap for developer locations.
  39. Blogmania: Your first (and possibly only) stop could be Jendrik Illner's, which summarizes all sorts of graphics-related posts. Also, most bloggers (and non-bloggers) also have a Twitter feed - find and follow them. You can also follow individual blogs with one of these: Our own, Ben Golus, Humus, Lost in the Triangles, Casual Effects, Self Shadow, C0DE517E, Bart Wronski, NVIDIA GameWorks Blog, Code & Visuals, Graphics Rants,, Diary of a Graphics Programmer, , DirectX Developer Blog, Pete Shirley's Graphics Blog, Mikkelsen and 3D Graphics, the ryg blog, Sébastien Lagarde, Ignacio Castaño, Gamasutra News, and Not active, but still with some worthwhile posts: Stingray, Industrial Arithmetic, I Get Your Fail (brilliant), The Little Grasshopper, Legalize Adulthood!,, Meshlab, Beyond3D, G Blog, Pandemonium, OpenGL Superbible, and Pixel, Too Many.... You'll often find yet more blogs linked from these pages.
  40. Real Artifacts - in no way critical, but I find myself looking for this link every few months so I'm putting it here for me.
Special bonus site: you need to visit it only once, but Maxima is worth listing here. It is a free version of Macsyma (which is similar to Mathematica and Maple). If you work with equations and do not have $1500 to spare, you need this.

If you know a site that you're simply shocked we don't list here, please let me know.

Resources Hosted Onsite

Beyond the books list and object/object intersections page, the major resources hosted here are:

Computer Programs and Services

Here are some computer programs and services we like, in rough order of awesomeness.
  • Dropbox - you should know this already, but just in case: creates a special folder that is shared by all your machines. You can also share with others privately or publicly. There are now plenty of competitors.
  • iPad: our only recommendation is GoodReader - lets you stuff and view documents onto your iPad, syncs nicely with Dropbox.
  • Ninite - installing stuff on a new PC? Save yourself a few hours by just checking off the things you want and getting one program to install them all, without prompts. Also a nice site for finding programs to try out.
  • WinDirStat (Disk Inventory X on the Mac) - shows where all your disk space has gone in an excellent visual fashion (with specular highlights!). Try clicking on everything you see in the display to get more info, delete, etc. Free.
  • Beyond Compare - an excellent file comparison program. It even compares images, also showing their alpha layer. Shareware, but the trial gives 30 days of use. Our review here.
  • LICEcap - icky name, nice utility for creating animated GIFs of what's happening on the screen. Use this for capturing program behavior, to show what problem a bug is causing.
  • cppcheck - super-easy to use and free, it will probably find some coding errors that your compiler didn't notice. More about it here.
  • Visual Assist X - if you use Microsoft's Visual Studio, this add-on makes it considerably more usable. Costs money after the 30 day trial, but worth it for professionals. More info here.
  • Visual Studio Code - the most confusing name for a product ever, it has nothing to do with the Visual Studio IDE. A nice, free text editor, good for JavaScript development in particular.
  • MeshLab is a free package that's good for mesh manipulation and translation. It's got rough edges all over - expect crashes and lockups on advanced functionality - but it's got a huge range of functions.
  • Assimp is an open source library that reads a wide variety of 3D model file formats (and writes out a few). It also can perform some mesh clean-up functions.
  • Easy 3D readers: tiny OBJ loader and tiny glTF loader.
  • 3D Viewers: there are lots; we like FBX Review, G3D Viewer (full website), and open3dmod, among others.
  • Screen capture: we've looked far and wide. FastStone Capture is shareware that costs $20, but does a lot, including annotation. Greenshot is a favorite free one.
  • Image viewers: it's a matter of taste and needs. IrfanView, XnView, and FastStone Image Viewer are popular generic viewers. ddsview lets you look at mipmap levels (for DDS) and examine colors and alpha easily (plus source code is available).
  • Video editing: the free version of DaVinci Resolve is supposed to be quite good.
  • Everything finds files and folders instantly.
  • Clover gives you a tabbed Windows Explorer, like a browser. Beware of newer versions, they appear to add pop up junk in Chinese.
  • Glary Utilities, free for home use, has worthwhile cleanup tools and other utilities.
  • Shader-related: NShader adds syntax highlighting for shaders developed in Visual Studio, or you can get most of the way there in MSVC by "Options | Text Editor | File Extension" and setting extension .fx (.fxh, etc.), choosing Microsoft Visual C++, then clicking "Add". Other shader-related tools are described here.
  • Debugging: start with RenderDoc if you need a graphics debugger.
  • Performance: there are many tools in this area, here's an (old) start.
