\title Basket Example
\section2 Basket in QML
The QML version of the basket example is very similar in
structure to the C++ version above, but much simpler.
We start by defining a viewport with a specific camera position:
\snippet quick3d/basket/qml/basket.qml 1
We then add an \l Item3D object to load the basket model and
apply the desired texture to it:
\snippet quick3d/basket/qml/basket.qml 2
And then we apply an animation to the rotation component of
the item's transform property:
\snippet quick3d/basket/qml/basket.qml 3
\section2 Basket in Qt3D
The Basket example shows how Qt3D can be used to draw an animated
object covered in a texture. The basic application shell is similar
to the \l{qt3d/teapot}{Hello Teapot} example. In this case, we create
the basket object and add a texture to it as follows:
\snippet qt3d/basket/basketview.cpp 1
For this animation, we want to spin the basket around its Y axis,
once every 2 seconds. We first declare an \c angle property in the
class declaration (calling \c{update()} will force the view to
redraw whenever the angle changes):
\snippet qt3d/basket/basketview.h 1
Then we create a QPropertyAnimation object that will update
\c angle every time through the event loop with a new value
between 0 and 360 degrees:
\snippet qt3d/basket/basketview.cpp 2
Now all we have to do is draw the basket using the \c angle
property every time \c{paintGL()} is called:
\snippet qt3d/basket/basketview.cpp 3
