Detailed Description

Encapsulates the necessary information to create an OpenGL texture image.

QAbstractTextureImage should be used as the means of providing image data to a QAbstractTextureProvider. It contains the necessary information: mipmap level, layer, cube face load at the proper place data into an OpenGL texture.

The actual data is provided through a QTextureDataFunctor that will be executed by Aspect jobs in the backend. QAbstractTextureImage should be subclassed to provide a functor and eventual additional properties needed by the functor to load actual data.

Note: : QAbstractTextureImage should never be shared. Expect crashes, undefined behavior at best if this rule is not respected.

QAbstractTextureImage::QAbstractTextureImage(Qt3DCore::QNode *parent = Q_NULLPTR)

Default constructs an instance of QAbstractTextureImage.

[protected] QAbstractTextureImage::QAbstractTextureImage(QAbstractTextureImagePrivate &dd, Qt3DCore::QNode *parent = Q_NULLPTR)

Copy constructor.

[virtual] QAbstractTextureImage::~QAbstractTextureImage()

The destructor.

[protected] void QAbstractTextureImage::copy(const Qt3DCore::QNode *ref)

[pure virtual] QTextureDataFunctorPtr QAbstractTextureImage::dataFunctor() const

void QAbstractTextureImage::update()

Triggers an update of the data functor that is sent to the backend.
