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.
Note: : QAbstractTextureImage should never be shared. Expect crashes, undefined behavior at best if this rule is not respected.
Property Documentation
face : Qt3DRender::QAbstractTexture::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:
| QAbstractTexture::CubeMapFace | face() const |
| void | setFace(QAbstractTexture::CubeMapFace face) |
Notifier signal:
| void | faceChanged(QAbstractTexture::CubeMapFace face) |
layer : int
Returns the layer of the texture image.
Access functions:
| int | layer() const |
| void | setLayer(int layer) |
Notifier signal:
| void | layerChanged(int layer) |
mipLevel : int
Holds the mipmap level of the texture image.
Access functions:
| int | mipLevel() const |
| void | setMipLevel(int level) |
Notifier signal:
| void | mipLevelChanged(int mipLevel) |
