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.

Property Documentation

cubeMapFace : Qt3DRender::QAbstractTextureProvider::CubeMapFace

Holds the cube map face of the texture image.

Note: The cube map face has a meaning only for TargetCubeMap and TargetCubeMapArray.

Access functions:

QAbstractTextureProvider::CubeMapFace cubeMapFace() const
void setCubeMapFace(QAbstractTextureProvider::CubeMapFace face)

Notifier signal:

void cubeMapFaceChanged(QAbstractTextureProvider::CubeMapFace cubeMapFace)

layer : int

Holds the layer of the texture image.

Access functions:

int layer() const
void setLayer(int layer)

Notifier signal:

void layerChanged(int layer)

mipmapLevel : int

Holds the mipmap level of the texture image.

Access functions:

int mipmapLevel() const
void setMipmapLevel(int level)

Notifier signal:

void mipmapLevelChanged(int mipmapLevel)
