Detailed Description

QAbstractTextureImage should be used as the means of providing image data to a QAbstractTexture. 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 QTextureImageDataGenerator 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.

Member Function Documentation

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

Constructs a new QAbstractTextureImage instance with parent as parent.

[slot] void QAbstractTextureImage::setFace(QAbstractTexture::CubeMapFace face)

Sets the texture image face to face. face

Note: Setter function for property face.

See also face().

[slot] void QAbstractTextureImage::setLayer(int layer)

Sets the layer of a texture to layer. layer

Note: Setter function for property layer.

See also layer().

[slot] void QAbstractTextureImage::setMipLevel(int level)

Sets the mip level of a texture to level. level

Note: Setter function for property mipLevel.

See also mipLevel().

[pure virtual protected] Qt3DRender::QTextureImageDataGeneratorPtr QAbstractTextureImage::dataGenerator() const

Implement this method to return the QTextureImageDataGeneratorPtr instance, which will provide the data for the texture image.

[protected] void QAbstractTextureImage::notifyDataGeneratorChanged()

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