- \example canvasswitch
- \since QtCanvas3D 1.0
- \title Canvas Switch Example
- \ingroup qtcanvas3d-examples
- \brief Switch between canvases on run-time
-
- The Canvas Switch example shows how to create a Canvas3D dynamically and how to switch between
- two canvases on run-time.
-
- \image canvasswitch-example.png
-
- \section1 Dynamic Canvas Creation
-
- First we'll add a function call to the \c{Component.onCompleted} of the main component:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 0
-
- The function handles the initial canvas creation:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 1
-
- In the function we create the Canvas3D dynamically:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 2
-
- We also need to anchor it to the layout we have added inside the function, as we'll call the
- function again when switching canvases.
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 3
-
- \section1 Switching Canvas
-
- First we import the content for both canvases:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 4
-
- Then, we have a button for switching the content we want to show:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 5
-
- The content switching itself is done by destroying the old canvas and
- creating a new one in the \c{Button}'s \c{onClicked}:
-
- \snippet canvasswitch/qml/canvasswitch/main.qml 6

- \example plasmaeffects
- \since QtCanvas3D 1.0
- \title Plasma Effects Example
- \ingroup qtcanvas3d-examples
- \brief Apply oldsk00l plasma effects into a canvas
-
- The Plasma Effects Example concentrates on showing how to use different shaders in Canvas3D.
- These shaders are of "old school graphics demo" variety that achieve their effects with raw
- computations based on combining output of trigonometrical functions in various ways. But they
- demonstrate how you can hand over high intensity calculations to the Graphics Processing Unit
- (GPU) when using QtCanvas3D.
-
- For a more thorough look into the QML side see the \l {Textured Cube Example} and
- for a more thorough look into the JavaScript side see the \l {Lit and Textured Cube Example}.
-
- \image plasmaeffects-example.png
-
- \section1 Initialization
-
- During \c{initGL}'s shader initialization, we'll create two separate shader programs.
-
- First for the cubes:
-
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 0
-
- Then for the background:
-
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 1
-
- We'll need to use them one by one to get the uniform locations:
-
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 2
- \dots 0
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 3
-
- \section1 Usage
-
- To use the shaders, simply take the right one into use before drawing in \c{renderGL}:
-
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 4
- \dots 0
- \snippet plasmaeffects/qml/plasmaeffects/plasmaeffects.js 5

- \example pureqml
- \since QtCanvas3D 1.0
- \title Pure QML Example
- \ingroup qtcanvas3d-examples
- \brief A pure QML application project
-
- The Pure QML Example demonstrates the use of Canvas3D in a pure Qt Quick UI project, that
- has no compilable parts at all. It also briefly demonstrates how to interact with the object
- in Canvas3D using a MouseArea.
-
- \image pureqml-example.png
-
- \section1 Pure QML
-
- Our main qml file is similar to a normal Qt Quick Application. The main difference is that
- there is no \c{.pro} file and nothing to compile. We create the Canvas3D the normal way:
-
- \snippet pureqml/pureqml.qml 0
-
- \section1 MouseArea Interaction
-
- We added properties for x and y rotations into the Canvas3D:
-
- \snippet pureqml/pureqml.qml 1
-
- Then we add a \c MouseArea that fills the whole window, and connect the Canvas3D properties
- to \c mouseX and \c mouseY on their correspodinh onChanged functions:
-
- \snippet pureqml/pureqml.qml 2
-
- An finally, we just use the Canvas3D properties on the JavaScript side directly for matrix
- rotations:
-
- \snippet pureqml/cube.js 0
-

- \since QtCanvas3D 1.0
- \title Textured Cube Example
- \ingroup qtcanvas3d-examples
- \brief A simple textured cube
-
- The Textured Cube example shows how to create a simple Canvas3D displaying a single moving
- textured cube.
-
- \image texturedcube-example.png
-
- \section1 Creating Canvas3D
-
- We'll add a Canvas3D component into the main component:
-
- \snippet texturedcube/qml/texturedcube/main.qml 0
- \dots
-
- Inside it, we catch the \c initGL and \c renderGL signals to forward the initialization
- and rendering calls to the js object:
-
- \snippet texturedcube/qml/texturedcube/main.qml 1
-
- \section1 The JavaScript Object
-
- First we import the js object in the QML:
-
- \snippet texturedcube/qml/texturedcube/main.qml 4
-
- In the \c initGL function of the js object, we initialize the OpenGL state. We also create the
- TextureImage and register handlers for image load success and fail signals. In the case of
- load success the OpenGL texture is created and the loaded image is used to fill the texture
- with pixel data:
-
- \snippet texturedcube/qml/texturedcube/texturedcube.js 0
-
- The \c renderGL function does the actual drawing into the canvas:
-
- \snippet texturedcube/qml/texturedcube/texturedcube.js 1
-
- \section1 The Animation
-
- Animating the cube is done simply by adding a \c SequantialAnimation for different Canvas3D
- properties. Here's one as an example, affecting the x rotation of the cube:
-
- \snippet texturedcube/qml/texturedcube/main.qml 5
