+ \example canvas3d/threejs/oneqt
+ \since QtCanvas3D 1.0
+ \title One Qt Example
+ \ingroup qtcanvas3d-examples
+ \brief Demonstrates combining Qt Quick and three.js rendering.
+
+ One Qt example demonstrates how to implement a simple QML 3D control that combines the use
+ of \c{three.js} library-based Canvas3D rendering with Qt Quick 2D elements. The example shows
+ a view with various benefits of using Qt with related images picked from
+ \l {http://qt.io} {http://qt.io}. The images are displayed on the side of a spinning 3D cube
+ that spins to show the correct image when the tabs at the top of the application are selected.
+ You can also use swipe gestures to spin the cube to navigate between the tabs. The 3D cube
+ control has been implemented as a simple QML type that internaly uses \c{three.js} library and
+ \l{Qt Canvas 3D}.
+
+ \image oneqt-example.png
+
+ \section1 Main QML File
+
+ In \l{canvas3d/threejs/oneqt/oneqt.qml}{oneqt.qml}, we build the 2D content as normal in QML.
+ Then we add a custom \c {ImageCube} type into the scene behind the text elements.
+ This custom type, implemented using \c{three.js} library, handles the painting of the 3D
+ cube.
+
+ \snippet canvas3d/threejs/oneqt/oneqt.qml 0
+ \dots
+
+ \note The \c {ImageCube} 3D UI component can be created and anchored just like any other
+ QML type.
+
+ \section1 The Custom 3D QML Control
+
+ The \l{canvas3d/threejs/oneqt/ImageCube.qml}{ImageCube.qml} takes six images that it loads
+ and places to the sides of the cube. In addition, the type has a state that defines which of
+ these images are visible and a \c {backgroundColor} property that is used when painting the 3D
+ cube. The \c {angleOffset} property can be used to adjust the cube's direction when displaying
+ the selected image. In this example the cube component sits on the right edge of the screen so
+ we twist it slightly to the left so that it appears to be facing the rest of the content.
+ This angle is also used by the 3D light so that the light always illuminates the selected face
+ of the cube.
+
+ \snippet canvas3d/threejs/oneqt/ImageCube.qml 0
+ \dots
+
+ The custom type defines six states, one for each side of the cube along with the x-, y-, and
+ z-rotations, that must be set to show the face of the cube corresponding to the state.
+
+ \snippet canvas3d/threejs/oneqt/ImageCube.qml 1
+ \dots
+
+ We use \c {RotationAnimation} to animate the transition between angles. It enables us to get
+ smooth transitions between different cube orientations and to always rotate the cube along the
+ shortest possible angle distance.
+
+ \snippet canvas3d/threejs/oneqt/ImageCube.qml 2
+ \dots
+
+ We call the JavaScript code that uses \c{three.js} to do the rendering of the cube, calling
+ it on the \c{initializeGL}, \c{paintGL}, and \c{resizeGL} signals.
+
+ \snippet canvas3d/threejs/oneqt/ImageCube.qml 3
+
+ \section1 The JavaScript Code
+
+ The JavaScript side of the implementation,
+ \l{canvas3d/threejs/oneqt/imagecube.js}{imagecube.js},
+ is done using a version of \c{three.js} that is ported for \l{Qt Canvas 3D}:
+ \l{https://github.com/tronlec/three.js}{three.js}.
+
+ In \l{canvas3d/threejs/oneqt/imagecube.js}{imagecube.js}, we start by creating the camera and
+ the scene that contains all the rest of the \c{three.js} objects.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 0
+ \dots
+
+ Then we start the asynchronous loading of the textures and create a material array for the sides
+ of the cube (note that the cube needs 12 materials as each side consists of two triangles).
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 1
+ \dots
+
+ We then create the needed geometry as \c {BoxGeometry} binding the created materials to the
+ faces of the cube. We then create a \c {MeshFaceMaterial} from the array of materials.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 2
+
+ Finally we create the cube mesh from the geometry and material, position it, and add it
+ to the 3D scene.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 3
+
+ Next we create and add some lights to the scene. \c{AmbientLight} defines the surrounding light
+ amount and the directional light is positioned so that it highlights the face of the cube that
+ is currently selected.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 6
+
+ Final step in the initialization phase is to create the \c {Canvas3D} renderer and set the
+ initial size and clear color (color of the background) to the renderer.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 4
+
+ When we need to render the scene in response to the \c{paintGL} signal from Canvas3D, we just
+ copy the current rotation values from the QML side to the cube mesh in the \c{paintGL()} method.
+
+ \snippet canvas3d/threejs/oneqt/imagecube.js 5
+
+ For more information on how to use \c {three.js} the documentation is available here:
+ \l{http://threejs.org/docs/}{three.js/docs}

+/*!
+ \example canvas3d/threejs/planets
+ \since QtCanvas3D 1.0
+ \title Planets Example
+ \ingroup qtcanvas3d-examples
+ \brief Demonstrates combining Qt Quick and three.js rendering.
+
+ The Planets example demonstrates how to implement an application that combines the use of
+ three.js library-based Canvas3D rendering with Qt Quick 2D elements. The example shows the eight
+ planets of our Solar System with the Sun.
+
+ \image planets-example.jpg
+
+ The planets are rotating around the Sun based on their orbit at a given time. The rotation
+ starts at 2000 Jan 0.0 UT. The planet positions are calculated based on the formulas found here:
+ \l {http://www.stjarnhimlen.se/comp/ppcomp.html}{http://www.stjarnhimlen.se/comp/ppcomp.html}
+ and \l {http://www.davidcolarusso.com/astro/}{http://www.davidcolarusso.com/astro/}.
+
+ \section1 Qt Quick Implementation
+
+ The Qt Quick Implementation \l{canvas3d/threejs/planets/planets.qml}{planets.qml} of the example
+ renders the 3D content using Canvas3D type. The type calls JavaScript code that uses
+ \c{three.js} to initialize, paint, and resize the 3D view.
+
+ \snippet canvas3d/threejs/planets/planets.qml 0
+
+ The planet related information is stored into \c{ListModel}. The selection buttons for the
+ planets and the information sheet are created based on the model. The 2D elements, selection
+ buttons and sliders, are implemented in the QML side.
+
+ The selection buttons change the \c{focusedPlanet} property of the mainview. As the property
+ changes the planet information is updated and the camera is animated to the new position. The
+ camera position and the camera look at point are updated based on values that are animated on
+ QML side.
+
+ \snippet canvas3d/threejs/planets/planets.qml 1
+
+ The sliders are used to adjust the rotation speed, the planet size, and the viewing distance.
+ When the slider value changes, JavaScript code is called to adjust the given property. For
+ example, changing the value of the "Viewing Distance" slider calls the \c{setCameraDistence()}
+ method.
+
+ \snippet canvas3d/threejs/planets/planets.qml 2
+
+ \section1 The JavaScript Code
+
+ The JavaScript side of the implementation, \l{canvas3d/threejs/planets/planets.js}{planets.js},
+ is done using a version of \c{three.js} that is ported for \l{Qt Canvas 3D}:
+ \l{https://github.com/tronlec/three.js}{three.js}.
+
+ The \c{initializeGL()} method creates the camera and the scene. It also adds the lights to the
+ scene and creates the planet meshes. The Canvas3D renderer needs to be created at initialization
+ phase too.
+
+ Planet texture maps are Copyright (c) by James Hastings-Trew
+ \l{http://planetpixelemporium.com/planets.html}{http://planetpixelemporium.com/planets.html}
+ used with permission. To calculate the ring geometry for the planets with rings, the
+ \c{_RingGeometry()} method from
+ \l{https://github.com/jeromeetienne/threex.planets}{three.xplanets} extension is used.
+
+ The scene is rendered in \c{paintGL()} method. That is also the place where the positions for
+ all of the planets are calculated. The planets are rotated based on their axial tilt and their
+ sidereal rotation period. In the \c{paintGL()} method the camera position and look at point are
+ updated based on the focused planet.
+
+ For more information on how to use \c {three.js} the documentation is available here:
+ \l{http://threejs.org/docs/}{three.js/docs}
+
+ \section1 Handling the Mouse Events
+
+ In order to handle the mouse event in JavaScript code the Canvas3D type has to include the
+ \c{ControlEventSource} type.
+
+ \snippet canvas3d/threejs/planets/planets.qml 3
+
+ This type is then passed to the JavaScript code on initialization.
+
+ \snippet canvas3d/threejs/planets/planets.qml 4
+
+ On JavaScript code in the \c{initializeGL()} method the \c{eventSource} object is saved to a
+ global variable. In this example \c{mouseDown} event is connected to the
+ \c{onDocumentMouseDown()} method.
+
+ \snippet canvas3d/threejs/planets/planets.js 5
+
+ Based on the mouse position variables passed to \c{onDocumentMouseDown()} method, it's checked
+ if the event takes place on top of a planet or not. The focused planet is changed according to
+ the mouse position.

- \example threejs/oneqt
- \since QtCanvas3D 1.0
- \title One Qt Example
- \ingroup qtcanvas3d-examples
- \brief Demonstrates combining Qt Quick and three.js based rendering.
-
- One Qt example demonstrates how to implement an application that combines the use of three.js
- library based Canvas3D rendering with Qt Quick 2D elements.
-
- \image oneqt-example.png
-
- \section1 Qt Quick Implementation
-
- In \l{threejs/oneqt/oneqt.qml}{oneqt.qml}, we build the 2D content as normally in Qt Quick.
- Then we add a custom ImageCube element in to the scene as the background element. This custom
- component fills the whole parent area and handles the painting of the background and the 3D cube
- for this view.
-
- \snippet threejs/oneqt/oneqt.qml 0
- \dots
-
- The custom component takes six images that it loads and places to the sides of the cube.
- In addition the component has a state that defines which of these images is visible.
-
- \section2 The Custom 3D Qt Quick Element
-
- In \l{threejs/oneqt/ImageCube.qml}{ImageCube.qml}, we define the cube rotation related
- properties and properties that contain the image file URLs to be loaded for the cube sides.
-
- \snippet threejs/oneqt/ImageCube.qml 0
- \dots
-
- The custom component defines six states, one for each side of the cube along with the x, y and
- z rotations that must be set to show that face of the cube.
-
- \snippet threejs/oneqt/ImageCube.qml 1
- \dots
-
- We use Qt Quick transitions to animate between the angles to get smooth transitions between
- different cube orientations.
-
- \snippet threejs/oneqt/ImageCube.qml 2
- \dots
-
- Finally we call the JavaScript code that uses three.js to do the rendering of the cube, calling
- it on the initializeGL, paintGL and resizeGL signals.
-
- \snippet threejs/oneqt/ImageCube.qml 3
-
- \section2 The three.js Code
-
- In \l{threejs/oneqt/imagecube.js}{imagecube.js}, we start by creating the camera and scene.
-
- \snippet threejs/oneqt/imagecube.js 0
- \dots
-
- Then we start the asynchronous loading of the textures and create a material array for the sides
- of the cube (note that the cube needs 12 materials as each side consists of two triangles).
-
- \snippet threejs/oneqt/imagecube.js 1
- \dots
-
- We then create the needed geometry as BoxGeometry binding the just created materials to the
- faces of the cube. We then create a MeshFaceMaterial from the array of materials.
-
- \snippet threejs/oneqt/imagecube.js 2
-
- Finally we create the cube mesh from the geometry and material, we position it and add it
- to the 3D scene.
-
- \snippet threejs/oneqt/imagecube.js 3
-
- Next we create and add some lights to the scene. AmbientLight defines the "surrounding light"
- amount and the directional light is positioned so that it highlights the face of the cube facing
- directly towards the camera.
-
- \snippet threejs/oneqt/imagecube.js 6
-
- Final step in the initialization phase is create the Canvas3D renderer and set the
- initial size and clear color (color of the background) to the renderer.
-
- \snippet threejs/oneqt/imagecube.js 4
-
- When we need to render the scene in response to the paintGL signal from Canvas3D we just copy
- the current rotation values from the Qt Quick component to the cube mesh in paintGL method.
-
- \snippet threejs/oneqt/imagecube.js 5
