 * Runtime reloading of modified GLSL shaders attached to objects within scenes.
 * Multiple views of a scene at one time.
 * Camera control modes such as panning, orbiting, or following objects.
 * Save / load for scene data. The current inheritance model is temporary.
 * Basic text editor for quickly modifying shaders attached to objects.
 * Shader / object properties panel to modify related settings.
 * Reduce size of application resources and git references.
 The Qtk desktop application provides a model loader
 using [Assimp](https://assimp.org/) within a Qt widget application.
 For examples of using the Qtk API, see the `example-app` project in the root of
 this repository.
 To get textures loading on models look
 into [material files](http://www.paulbourke.net/dataformats/mtl/)
 and see some examples in the `resources/models/` directory.
 ### Source Builds
 Qtk was developed and tested using CLion
 and [Qt Creator](https://github.com/qt-creator/qt-creator).
 Simply open the root `CMakeLists.txt` with either of these editors and
 configurations will be loaded.
 This project has been ported to **Qt 6.6.0**, which is not yet available in
 Ubuntu apt repositories.
 To run this project, you will *need* to
 install [Qt6 Open Source Binaries](https://www.qt.io/download-qt-installer) for
 your system, **version 6.6.0** or later.
 Be sure to take note of the Qt6 installation directory, as we will need it to
 correctly set our `CMAKE_PREFIX_PATH` in the next steps.
 If you are building on **Windows / Mac**, consider setting
 the `-DQTK_ASSIMP_NEW_INTERFACE` cmake build option.
 If the build is configured with all options enabled, we can subsequently install
 individual components as needed with cmake.
 Once Qt6 is installed, to build and run `qtk` on Ubuntu -
 ```bash
-sudo apt update -y && sudo apt install libassimp-dev cmake build-essential git ccache libgl1-mesa-dev libglvnd-dev zlib1g-dev -y
+sudo apt update -y && sudo apt install libassimp-dev cmake build-essential git
-git clone https://github.com/shaunrd0/qtk
+git clone https://gitlab.com/shaunrd0/qtk && cd qtk
-cd qtk
+mkdir build && cd build
-# Configure the build with all components enabled
+cmake .. -DCMAKE_PREFIX_PATH=$HOME/Qt6/6.2.3/gcc_64 && cmake --build .
-cmake -B build-all -DQTK_GUI=ON -DQTK_PLUGINS=ON -DQTK_EXAMPLE=ON -DCMAKE_PREFIX_PATH=$HOME/Qt/6.6.0/gcc_64
+./qtk
 # Build all targets
 cmake --build build-all/
 ````
 By default, the build will not initialize Assimp as a git submodule and build
 from source.
 We can turn this on by setting the `-DQTK_SUBMODULES=ON` flag when running
 CMake.
 Building using this option will fetch and build Assimp for us, but builds will
 take longer as a result.
 Using `-DQTK_SUBMODULES=ON` supports providing assimp on cross-platform builds (
 Windows / Mac / Linux) and may be easier
 to configure.
 ```bash
 cmake -B build-all -DQTK_GUI=ON -DQTK_PLUGINS=ON -DQTK_EXAMPLE=ON -DQTK_SUBMODULES=ON -DCMAKE_PREFIX_PATH=$HOME/Qt/6.6.0/gcc_64
 ```
 #### Qtk GUI
 ```bash
 cmake --build build-all/ --target qtk_gui -- -j $(nproc)
 # Install Qtk desktop application (output removed)
 # Installation prefix path must be absolute, since Qtk uses Qt deploy tools.
 cmake --install build-all/ --component qtk_gui --prefix=$(pwd)/install
 ./install/bin/qtk_gui
 ```
 If any errors are encountered loading plugins, we can debug plugin loading by
 setting the following environment variable -
 ```bash
 QT_DEBUG_PLUGINS=1 ./install/bin/qtk_gui
 ```
 #### Qtk Library
 Qtk provides a simple library for working with QOpenGL.
 We can install this library on a system path or a custom path and then
 set `CMAKE_PREFIX_PATH` to point to this location when building an application
 using libqtk.
 ```bash
 # Install libqtk only
 cmake --build build-all/ --target qtk_library -- -j $(nproc)
 cmake --install build-all/ --component qtk_library --prefix=/usr/local
 -- Install configuration: "Release"

 ```
 #### Qtk Plugin Collection
 This project defines a collection of widget plugins for use with Qt Designer.
 These plugins were used to build the interface for the Qtk desktop application.
 Qt Designer will list Qtk widgets in the side panel when editing a UI file
 within the designer.
 Qtk widgets will also render and behave correctly within the UI preview in
 designer.
 The widgets in the Qtk collection were created by implementing
 the [QDesignerCustomWidgetInterface](https://doc.qt.io/qt-6/qdesignercustomwidgetinterface.html#details)
 and [QDesignerCustomWidgetCollectionInterface](https://doc.qt.io/qt-6/qdesignercustomwidgetcollectioninterface.html)
 interfaces.
 To build and install the Qtk plugin collection -
 ```bash
 cmake --build build-all/ --target qtk_plugins -- -j $(nproc)
 # Install Qtk widget collection to use Qt Designer
 # The path here should be initialized during build configuration, so no need for --prefix
 cmake --install build-all/ --component qtk_plugins
 -- Install configuration: "Release"
 -- Up-to-date: /home/shaun/Qt/6.6.0/gcc_64/../../Tools/QtCreator/lib/Qt/lib/libqtk_library.a
 -- Up-to-date: /home/shaun/Qt/6.6.0/gcc_64/../../Tools/QtCreator/lib/Qt/lib/libqtk_plugin_library.a
 -- Up-to-date: /home/shaun/Qt/6.6.0/gcc_64/../../Tools/QtCreator/lib/Qt/plugins/designer/libqtk_collection.so
 ```
 To uninstall after a previous installation, we can run the following command
 from the root of the repository.
 ```bash
 xargs rm < build/install_manifest.txt
 ```
 #### Qtk Example
 There is a simple example of using libqtk in the [example-app/](example-app)
 directory. The example can be built standalone using `find_package` or as a
 target within any qtk build.
 ```bash
 # Build the example from a configured qtk build tree
 cmake --build build-all/ --target qtk_example -- -j $(nproc)
 cmake --install build-all/ --component qtk_example --prefix=install
 ./install/bin/qtk_example
 ```
 See the README in the [example-app/](example-app) subdirectory for instructions
 on standalone builds.
 ### Controls
 You can fly around the scene if you hold the right mouse button and use WASD.
 If you see a small triangle floating by a model it represents the light source
 that is being used for the shader rendering the model. These appear on models
 using phong, specular, and diffuse lighting techniques.
 Object names can be double-clicked in the tree view panel for quick camera
 navigation. All panels and toolbars are dockable widgets that can be popped out
 and reorganized as needed. Panels can be stacked to create a docked widget with
 tabs. The central widget that provides the camera view into the scene cannot be
 detached from the main window in this way. See the `View` menu to enable debug
 console widgets for open scenes or reopen previously closed panels.

 #### Development
 This project uses version `15.0.5` of `clang-format`.
 Before merging any branch we should run `clang-tidy` followed by `clang-format`.
 ```bash
 git clone git@github.com:llvm/llvm-project.git -b llvmorg-15.0.5
 cd llvm-project
 cmake -B build -DLLVM_ENABLE_PROJECTS=clang -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi" -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" llvm
 cmake --build build -j $(nproc --ignore=2)
 sudo cmake --build build -j $(nproc --ignore=2) --target install
 ```
 If the `clang-format` version is any earlier than `15.0.0`,
 running `clang-format` will fail because this project uses configuration options
 made available since `15.0.0`.
 ```bash
 clang-format --version
 clang-format version 15.0.5 (git@github.com:llvm/llvm-project.git 154e88af7ec97d9b9f389e55d45bf07108a9a097)
 ```
 CLion has integration for IDE code reformatting actions with `clang-format`.
 If you're using CLion, the `.clang-format` configuration will be picked up by
 CLion automatically.
 `clang-tidy` can be run with the following commands.
 ```bash
 # Move to the root of the repo
 cd qtk
 # Build
 cmake -B build && cmake --build build -- -j $(nproc)
 clang-tidy -p build/ --fix --config-file=.clang-tidy src/*.cpp src/*.h app/*.cpp app/*.h
 ```
 Last we need to run `clang-format`, this can be done with the command directly.
 This will reformat all the code in the repository.
 ```bash
 clang-format -i --style=file:.clang-format src/app/*.cpp src/app/*.h src/qtk/*.cpp src/qtk/*.h example-app/*.cpp example-app/*.h
 ```
 `clang-format` can be run with git integration (or CLion if you prefer).
 Git will only reformat the lines you modified, which can be useful.
 ```bash
 # If we want to format the last N commits
 # git clang-format HEAD~N
 # 3 commits
 git clang-format HEAD~3
 changed files:
    app/examplescene.h
    app/mainwindow.h
    src/abstractscene.cpp
    src/skybox.h
    src/texture.cpp
    src/texture.h
    src/transform3D.h
 ```
 ##### Packaging
 Packaging for Qtk is in early development.
 This section documents how to package Qtk, but only source builds have been
 verified on Windows / Mac / Linux.
 For this reason, it is recommended to install Qtk by strictly building from
 source at this time.
 Below are the steps to package a Qtk release.
 ```bash
 cd /path/to/qtk && cmake -B build
 # Package Qtk
 cmake --build build --target package
 # Package Qtk including source files
 cmake --build build --target package_source
 ```
 Alternatively, we can use `cpack` directly -
 ```bash
 cd /path/to/qtk && cmake -B build
 # Generate all install packages
 cpack -C Release
 # Generate a specific archive package (ZIP)
 cpack -C Release -G ZIP
 # Generate a specific archive package (TGZ)
 cpack -C Release -G TGZ
 # Generate debian package (DEB)
 cpack -C Release -G DEB
 # Generate NSIS install package (NSIS)
 cpack -C Release -G NSIS
 ```
 Any of the above options can be appended with `--trace-expand` to debug package
 generation issues.
 The contents of all packages will depend on how the build was configured.
 To generate packages for Qtk desktop application, we should
 set `-DQTK_GUI=ON`. If this option is not set we will only package libqtk.
 The NSIS installer will allow component-specific path modification for all of

 This is an example application that is using the Qtk API to create custom Qt
 OpenGL widgets. This is very similar to `QtkWidget` in the Qtk desktop
 application source code, but could be modified for different uses if needed.
 There are no camera controls supported in this example. The camera is fixed.
 If these controls are desired, they can be implemented by the client.
 You can import your own models within `examplescene.cpp`, inside the
 `ExampleScene::init()` function. Rotations and translations
 are applied in `ExampleScene::update()`.
 The syntax for adding shapes and models is seen in the example below.
 This would result in a scene with a red cube and a miniature spartan model
 placed on top.
 ```C++
 void ExampleScene::init() {
  // Add a skybox to the scene using default cube map images and settings.
  setSkybox(new Qtk::Skybox("Skybox"));
  /* Create a red cube with a mini master chief on top. */
  auto myCube = new MeshRenderer("My cube", Cube(Qtk::QTK_DRAW_ELEMENTS));
  myCube->setColor(RED);
  mMeshes.push_back(myCube);
  auto mySpartan = new Model("My spartan", "/path/to/spartan/spartan.obj");
  mySpartan->getTransform().setTranslation(0.0f, 0.5f, 0.0f);
  mySpartan->getTransform().setScale(0.5f);
  mModels.push_back(mySpartan);
 }
 ```
 If we want to make our spartan spin, we need to apply rotation in `update`
 ```C++
 void ExampleScene::update() {
  auto mySpartan = Model::getInstance("My spartan");
  mySpartan->getTransform().rotate(0.75f, 0.0f, 1.0f, 0.0f);
  auto myCube = MeshRenderer::getInstance("My cube");
  myCube->getTransform().rotate(-0.75f, 0.0f, 1.0f, 0.0f);
 }
 ```
 Other examples can be found in the source files for this example project.
 ## Build Instructions
 Currently, this application requires manual build and installation of Qtk.
 In the future, once a release is published, I will be able to use `FetchContent`
 or similar cmake functionality to remove this requirement.
 For Qtk build instructions, see the README in the root of this repository.
 ```bash
 cmake -S /path/to/qtk/example-app/ -B /path/to/qtk/example-app/build
 cmake --build /path/to/qtk/example-app/build
 ```
 If Qtk was not installed system-wide, we can set `QTK_PATH` to point to the
 custom installation directory.
 ```bash
 cmake -S /path/to/qtk/example-app/ -B /path/to/qtk/example-app/build -DQTK_PATH=/path/to/qtk/install/
 cmake --build /path/to/qtk/example-app/build --target qtk_example -- -j $(nproc)
 cmake --install build/ --component qtk_example
 ```
 After this, we can run the example application -
 ```bash
 ./path/to/qtk/example-app/build/install/bin/example
 ```

 SIL OPEN FONT LICENSE
 Version 1.1 - 26 February 2007
 PREAMBLE
 The goals of the Open Font License (OFL) are to stimulate worldwide
 development of collaborative font projects, to support the font creation
 efforts of academic and linguistic communities, and to provide a free and
 open framework in which fonts may be shared and improved in partnership
 with others.
 The OFL allows the licensed fonts to be used, studied, modified and
 redistributed freely as long as they are not sold by themselves. The
 fonts, including any derivative works, can be bundled, embedded,
 redistributed and/or sold with any software provided that any reserved
 names are not used by derivative works. The fonts and derivatives,
 however, cannot be released under any other type of license. The
 requirement for fonts to remain under this license does not apply
 to any document created using the fonts or their derivatives.
 DEFINITIONS
 "Font Software" refers to the set of files released by the Copyright
 Holder(s) under this license and clearly marked as such. This may
 include source files, build scripts and documentation.
 "Reserved Font Name" refers to any names specified as such after the
 copyright statement(s).
 "Original Version" refers to the collection of Font Software components as
 distributed by the Copyright Holder(s).
 "Modified Version" refers to any derivative made by adding to, deleting,
 or substituting — in part or in whole — any of the components of the
 Original Version, by changing formats or by porting the Font Software to a
 new environment.
 "Author" refers to any designer, engineer, programmer, technical
 writer or other person who contributed to the Font Software.

 binary files as long as those fields can be easily viewed by the user.
 3) No Modified Version of the Font Software may use the Reserved Font
 Name(s) unless explicit written permission is granted by the corresponding
 Copyright Holder. This restriction only applies to the primary font name as
 presented to the users.
 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
 Software shall not be used to promote, endorse or advertise any
 Modified Version, except to acknowledge the contribution(s) of the
 Copyright Holder(s) and the Author(s) or with their explicit written
 permission.
 5) The Font Software, modified or unmodified, in part or in whole,
 must be distributed entirely under this license, and must not be

 * Example scene using QtkWidget to render 3D models and simple geometry within

 *
 * The Qtk::Scene base class provides containers for N pointers to MeshRenderer
 * and Model objects. We can create and insert as many as we like within this
 * child class implementation. This child class does not need to manually draw
 * objects inserted into these containers. The child class would only need to
 * update uniform or other data that may change per-frame.
 * See scene.h and `init()` for more information.
 *
 * To modify the scene objects should be initialized within the `init()` public
 * method. Any required movement or updates should be applied within `draw()` or
 * `update()`.
