===== gloom

A minimalistic boilerplate for OpenGL with C++ derived from Glitter. Its intended use is to get smaller OpenGL projects quickly up and running for the graphics courses at NTNU.

The following libraries are included with this project:

+---------+---------------------------------------+ | Library | Function | +=========+=======================================+ | glad_ | OpenGL function loader | +---------+---------------------------------------+ | glfw_ | Window creation and input handler | +---------+---------------------------------------+ | glm_ | OpenGL mathematics | +---------+---------------------------------------+ | stb_ | Various libraries, e.g. image loading | +---------+---------------------------------------+

Additional functionality can be added by altering CMakeLists.txt.

Dependencies

• CMake_ (v.3.*) is used to generate platform-specific makefiles and workspaces.

Please refer to the individual library repositories for more information about additional dependencies.

Getting started

Download

The project and all third-party libraries can be downloaded by cloning this repository with the --recursive flag.

.. code-block:: bash

git clone --recursive https://github.com/senbon/gloom.git

If you have already cloned the repository and missed the --recursive flag, then the following grabs all dependencies.

.. code-block:: bash

git submodule update --init

Compilation

Linux (command-line)

With all dependencies installed, compiling the project is as easy as running CMake followed by the ``make`` command.

.. code-block:: bash

  # Change into the directory where you want your makefiles
  cd ./gloom/build

  # Generate UNIX Makefile (point CMake to CMakeLists.txt)
  cmake ..

  # Execute make command
  make

  # Run executable
  ./gloom/gloom

Specific generators can also be specified with CMake if you want to create workspaces for an IDE, for example:

.. code-block::

  cmake -G "CodeBlocks - Unix Makefiles"


Windows (cmake-gui)
~~~~~~~~~~~~~~~~~~~

1. Set the source code file to the root directory containing ``CMakeLists.txt``
2. Binaries can be built in the directory of your choice, e.g. ``gloom\build\``
3. Click the configure button and select which generator you would like to use
4. Click the generate button
5. If your generator is an IDE such as Visual Studio, then open up the newly created .sln file and build ``ALL_BUILD``. After this you might want to set ``gloom`` as you StartUp Project.

Documentation
=============

The full documentation can be found on the `repository wiki`_.
Among other things, the wiki includes information on how to use the shader and camera class bundled with gloom.
