详细描述
Encapsulates the necessary information to create an OpenGL texture image from an image source.
It contains the necessary information mipmap level, layer, cube face and source URL to load at the proper place data into an OpenGL texture.
成员类型
enum QTextureImage::Status
This enumeration specifies the status values for texture image loading.
| Constant | Value | Description |
|---|---|---|
Qt3DRender::QTextureImage::None | 0 | The texture image loading has not been started yet. |
Qt3DRender::QTextureImage::Loading | 1 | The texture image loading has started, but not finised. |
Qt3DRender::QTextureImage::Ready | 2 | The texture image loading has finished. |
Qt3DRender::QTextureImage::Error | 3 | The texture image loading confronted an error. |
属性
mirrored : bool
This property specifies whether the image should be mirrored when loaded. This is a convenience to avoid having to manipulate images to match the origin of the texture coordinates used by the rendering API. By default this property is set to true. This has no effect when using compressed texture formats.
Note: OpenGL specifies the origin of texture coordinates from the lower left hand corner whereas DirectX uses the the upper left hand corner.
Note: When using cube map texture you'll probably want mirroring disabled as the cube map sampler takes a direction rather than regular texture coordinates.

成员函数
QTextureImage::QTextureImage(Qt3DCore::QNode *parent = nullptr)
Default constructs an instance of QTextureImage.
bool QTextureImage::isMirrored() const
Returns whether mirroring is enabled or not.
Note: Getter function for property mirrored.
[protected] void QTextureImage::sceneChangeEvent(const Qt3DCore::QSceneChangePtr &change)
Sets the scene change event to change. change
[slot] void QTextureImage::setMirrored(bool mirrored)
Sets mirroring to mirrored.
Note: This internally triggers a call to update the data generator.
Note: Setter function for property mirrored.
参见 isMirrored().
[slot] void QTextureImage::setSource(const QUrl &source)
Sets the source url of the texture image to source.
Note: This internally triggers a call to update the data generator.
Note: Setter function for property source.
参见 source().
[protected] void QTextureImage::setStatus(Status status)
Sets the status to status. status
参见 status().
QUrl QTextureImage::source() const
Returns the source url from which data for the texture image will be loaded.
Note: Getter function for property source.
参见 setSource().
Status QTextureImage::status() const
Returns the current status.
Note: Getter function for property status.
参见 setStatus().
