Shaun Reed 194888ed19 Refactor build system and UI 
+ Install configs for Qt Designer plugins and Qtk application
+ Add Qtk plugin collection for Qt Designer
+ QtkWidget plugin
+ TreeView widget plugin
+ DebugConsole widget plugin
+ All widgets are fully integrated with Qt Designer
+ All widgets can be popped out or docked within the window
+ All widgets can be stacked to use tab view for side panels
+ All widgets can be toggled on/off through the view context menu
+ QtkWidget debug console
+ QtkWidget active scene TreeVew
+ QtkWidget dockable tool bar
+ Double-click an object name in the TreeView to focus camera
+ Separate libaray from widgets

There is still a lot to do here, but the major refactoring should be
done after this commit. Some of the new features were put together as
POC for working with the new UI. A few placeholder buttons were added
that have no functionality.

Model loader using [Assimp](https://assimp.org/) within a Qt widget application. Qtk is a Qt OpenGL graphics library created primarily for my own learning
purposes. The library wraps some QOpenGL functionality in convenience classes
that allow rendering geometry in 2D and 3D using custom GLSL shader programs.
You can import your own models within `app/examplescene.cpp`, inside the The long-term goal for this project is to create a tool that I can use to
`ExampleScene::init()` function. Rotations and translations practice shader coding or graphics programming techniques. In doing this I hope
happen in `ExampleScene::update()`. to also learn more about the Qt UI framework, and the CMake build system.
Key features that are planned:
* Runtime loading of `.obj` or similar 3D models.
* Drag-and-drop interaction for adding objects to the scene.
* 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.
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/) 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. and see some examples in the `resources/models/` directory.
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++
// From: qtk/app/examplescene.cpp
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", ":/models/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++
// From: qtk/app/examplescene.cpp
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);
}
```

By default, the build will initialize Assimp as a git submodule and build from source. By default, the build will not initialize Assimp as a git submodule and build from source.
We can turn this off by setting the `-DQTK_UPDATE_SUBMODULES=OFF` flag when running CMake. We can turn this on by setting the `-DQTK_UPDATE_SUBMODULES=ON` flag when running CMake.
This will greatly increase build speed, but we will need to make sure Assimp is available either system-wide or using a custom `CMAKE_PREFIX_PATH`. Building using this option will fetch and build Assimp for us, but builds will take longer as a result.
Using `-DQTK_UPDATE_SUBMODULES=ON` supports providing assimp on cross-platform builds (Windows / Mac / Linux) and may be easier to configure. Using `-DQTK_UPDATE_SUBMODULES=ON` supports providing assimp on cross-platform builds (Windows / Mac / Linux) and may be easier to configure.

### 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 -S /path/to/qtk -B /path/to/qtk/build -DCMAKE_PREFIX_PATH=$HOME/Qt/6.3.1/gcc_64
cmake --build /path/to/qtk/build --target qtk-collection
cmake --install /path/to/qtk/build
```
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
```
### 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.

cmake --build build --target package_source

# Generate all install packages
cpack -C Release
# Generate a specific install package (ZIP)
cpack -C Release -G ZIP
# Generate a specific install package (DEB)
cpack -C Release -G DEB
```
Spartan with normals - ##### Resources
![](resources/spartan-normals.png) Some useful links and resources that I have found while working on this project.
[Qt Designer UI file format](https://doc.qt.io/qt-6/designer-ui-file-format.html)
### QtkWidget in Qt Creator [QtPlugin Import / Export plugins](https://doc.qt.io/qt-6/qtplugin.html)
We can add more QtkWidgets to view and render the scene from multiple perspectives.
There is still some work to be done here, so there isn't a builtin way to add an additional view within the application.
![](resources/qtk-views.png)
After building Qtk, we can drag and drop an `OpenGL Widget` onto the `mainwindow.ui`.
Then right-click the new OpenGLWidget and `Promote To->QtkWidget` to add a second view.
![](resources/qtk-views-setup.png)
If we demote or delete all widgets in `mainwindow.ui` and rebuild the project, Qt Creator will drop `QtkWidget` from the list of possible promoted widgets.
Add an `OpenGL Widget` to the UI, right-click it and navigate to `Promote Widget...` and enter the information below.
![](resources/qtk-reference.png)
After you fill out the `New Promoted Class` form, click `Add` *and*`Promote`, then rebuild.
After following these steps Qt Creator will list `QtkWidget` as an option to promote `OpenGL Widgets` again.

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, but could be modified for different uses if needed.
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
```
After this, we can run the example application -
```bash
./path/to/qtk/example-app/build/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,

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.

contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or

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
