Welcome to the Flux Rendering Engine repository. This application is meant to be an exploration into modern rendering techniques used in the game industry. One of the major improvements over its progenitor Radiant are its Physically Based Rendering capabilities.

The first step is to pull the repository from GitHub. You can do this in any way you like, but here is one possible way:

1. Create a local folder for the project on your computer
2. Go into the folder and open GitBash or a terminal with git enabled
3. Execute the command git init to initialize the Git repository
4. Execute the command git remote add origin [email protected]:JulianThijssen/Flux.git to link your local repository to the remote GitHub one.
5. Fetch all branches from the repository using git fetch -a
6. Now you can pull in the source files from the master branch by executing git pull origin master
7. If you get a permission denied message on the last step be sure that you have an SSH-key pair and have added the public one to your GitHub account. See: https://help.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh

1. Launch CMake (available here: https://cmake.org/)
2. In the source code field browse to the local folder from the last section (which contains CMakeLists.txt).
3. In the build field copy the source code field but append /Build at the end. This will put all files necessary for building in the Build folder (it will create it if it doesn't exist).
4. Press Configure and select the generator for your IDE of choice with the platform of x64. Press Finish to configure the project.
5. If no errors appear in the CMake log on the bottom, press Generate to generate the solution for your given IDE.
6. Press Open Project to launch the IDE and the project.

1. At the top of Visual Studio set the build mode (where it says Debug) to Release.
2. Right click the project TestProject in the Solution Explorer and select Set as StartUp Project.
3. Right click the project Flux and press Build, if that succeeds, right click the TestProject project and press Build.
4. If all is well both builds should succeed and if you run the project with Ctrl+F5 it will launch TestProject.exe.

This depends on your IDE / compiler. Follow their instructions for compiling source code. The code is untested on these platforms.

A test scene is available at: https://github.com/JulianThijssen/Flux/releases/download/v0.1.0/TestScene.zip

Place the contents of this .zip file in a folder called res in your Build folder.
