base on Main Web Site (Online Books) Ray Tracing in One Weekend Book Series ==================================================================================================== | ![RT in One Weekend][cover1] | ![RT The Next Week][cover2] | ![RT The Rest of Your Life][cover3] | |:----------------------------:|:---------------------------:|:-----------------------------------:| | [In One Weekend][book1] | [The Next Week][book2] | [The Rest of Your Life][book3] | Getting the Books ------------------ The _Ray Tracing in One Weekend_ series of books are now available to the public for free directly from the web. ### Version 4.0.1 - [Ray Tracing in One Weekend][web1] - [Ray Tracing: The Next Week][web2] - [Ray Tracing: The Rest of Your Life][web3] These books have been formatted for both screen and print. For more information about printing your own copies, or on getting PDFs of the books, see [PRINTING.md][] for more information. Contributing ------------- If you'd like to contribute a PR _**please read our [contribution guidelines][CONTRIBUTING] first**_. Project Status --------------- Version 4 has shipped! Three and a half years in the making, with massive changes to all three books and accompanying code. Our current version is v4.0.1. If you'd like to check out the latest updates and watch our progress, we're on the `dev-patch`, `dev-minor`, and `dev-major` branches. You can also browse our issues and milestones to see what we're planning. If you're interested in contributing, email us! You can find our contact info at the head of each book. Or just start [a new discussion][discussions] or [issue][issues]. GitHub Discussions ------------------ Do you have general questions about raytracing code, issues with your own implmentation, or general raytracing ideas you'd like to share? Check out our [GitHub discussions][discussions] forum! Directory Structure ------------------- The organization of this repository is meant to be simple and self-evident at a glance: - `books/` -- This folder contains the three raytracing books (in HTML), and some supporting material. - `images/` -- Contains all of the images and figures of the books. Can also be used to compare your results. - `style/` -- Contains the css for the books and the site. - `src/` -- Contains the source. - `src/<book>/` -- Contains the final source code for each book. Source Code ----------- ### Intent This repository is not meant to act as its own tutorial. The source is provided so you can compare your work when progressing through the book. We strongly recommend reading and following along with the book to understand the source. Ideally, you'll be developing your own implementation as you go, in order to deeply understand how a raytracer works. ### Downloading The Source Code The [GitHub home][] for this project contains all source and documentation associated with the _Ray Tracing in One Weekend_ book series. To clone or download the source code, see the green "Clone or download" button in the upper right of the project home page. ### Programming Language This book is written in C++, and uses some modern features of C++11. The language and features were chosen to be broadly understood by the largest collection of programmers. It is not meant to represent ideal (or optimized) C++ code. ### Implementations in Other Languages The _Ray Tracing in One Weekend_ series has a long history of implementations in other programming languages (see [Implementations in Other Languages][implementations]), and across different operating systems. Feel free to add your own implementation to the list! ### Branches In general, ongoing development, with all of the latest changes, can be found in the `dev-patch`, `dev-minor`, and `dev-major` branches, minor and major changes, depending on the change level and release in progress. We try to keep CHANGELOG.md up to date, so you can easily browse what's new in each development branch. We may from time to time use additional development branches, so stay up to date by reviewing the [CONTRIBUTING][] page. The `release` branch contains the latest released (and live) assets. This is the branch from which GitHub pages serves up https://raytracing.github.io/. Building and Running --------------------- Copies of the source are provided for you to check your work and compare against. If you wish to build the provided source, this project uses CMake. To build, go to the root of the project directory and run the following commands to create the debug version of every executable: $ cmake -B build $ cmake --build build You should run `cmake -B build` whenever you change your project `CMakeLists.txt` file (like when adding a new source file). You can specify the target with the `--target <program>` option, where the program may be `inOneWeekend`, `theNextWeek`, `theRestOfYourLife`, or any of the demonstration programs. By default (with no `--target` option), CMake will build all targets. $ cmake --build build --target inOneWeekend ### Optimized Builds CMake supports Release and Debug configurations. These require slightly different invocations across Windows (MSVC) and Linux/macOS (using GCC or Clang). The following instructions will place optimized binaries under `build/Release` and debug binaries (unoptimized and containing debug symbols) under `build/Debug`: On Windows: ```shell $ cmake -B build $ cmake --build build --config Release # Create release binaries in `build\Release` $ cmake --build build --config Debug # Create debug binaries in `build\Debug` ``` On Linux / macOS: ```shell # Configure and build release binaries under `build/Release` $ cmake -B build/Release -DCMAKE_BUILD_TYPE=Release $ cmake --build build/Release # Configure and build debug binaries under `build/Debug` $ cmake -B build/Debug -DCMAKE_BUILD_TYPE=Debug $ cmake --build build/Debug ``` We recommend building and running the `Release` version (especially before the final render) for the fastest results, unless you need the extra debug information provided by the (default) debug build. ### CMake GUI on Windows You may choose to use the CMake GUI when building on windows. 1. Open CMake GUI on Windows 2. For "Where is the source code:", set to location of the copied directory. For example, `C:\Users\Peter\raytracing.github.io`. 3. Add the folder "build" within the location of the copied directory. For example, `C:\Users\Peter\raytracing.github.io\build`. 4. For "Where to build the binaries", set this to the newly-created "build" directory. 5. Click "Configure". 6. For "Specify the generator for this project", set this to your version of Visual Studio. 7. Click "Done". 8. Click "Configure" again. 9. Click "Generate". 10. In File Explorer, navigate to build directory and double click the newly-created `.sln` project. 11. Build in Visual Studio. If the project is succesfully cloned and built, you can then use the native terminal of your operating system to simply print the image to file. ### Running The Programs You can run the programs by executing the binaries placed in the build directory: $ build\Debug\inOneWeekend > image.ppm or, run the optimized version (if you compiled with the release configuration): $ build\Release\inOneWeekend > image.ppm The generated PPM file can be viewed directly as a regular computer image, if your operating system supports this image type. If your system doesn't handle PPM files, then you should be able to find PPM file viewers online. We like [ImageMagick][].
