About the Project

This is a repository resource loaded with high-resolution skyboxes for use with OpenGL (C++). Most of the skyboxes here are open source but are cited below for reference. Tutorials are linked below to demonstrate Photoshop's best practices for preserving detail and resolution when working with the images.

Function

The skyboxes use the following C++ function to create the skybox with OpenGL. Note that left and right are horizontally reflected. Also, front and back are horizontally reflected.

    vector<std::string> faces
    {
        "resources/textures/space/right.jpg", // right 
        "resources/textures/space/left.jpg", // left 
        "resources/textures/space/top.jpg", // top  
        "resources/textures/space/bottom.jpg", // bottom  
        "resources/textures/space/front.jpg", // front
        "resources/textures/space/back.jpg", // back
    };
    unsigned int cubemapTexture = texture.loadCubemap(faces)

XCode Usage

Open a terminal in the project directory and run the code to remove the old build folder and generate a new one with the Xcode project file.

mkdir build
cd build
cmake -G Xcode ..

#Usage: when updating the build folder, remove it first then regenerate the folder as above
rm -rf build 

Set the working directory in Xcode using Product > Scheme > Edit Scheme > Run Debug > Options > Working Directory > (Check Set Custom) > Project directory/build.

Build and run the project.
