Detailed Description¶
It contains the necessary information mipmap level, layer, cube face and source URL to load at the proper place data into an OpenGL texture.
- class Status¶
This enumeration specifies the status values for texture image loading.
Constant
Description
Qt3DRender.QTextureImage.None
The texture image loading has not been started yet.
Qt3DRender.QTextureImage.Loading
The texture image loading has started, but not finised.
Qt3DRender.QTextureImage.Ready
The texture image loading has finished.
Qt3DRender.QTextureImage.Error
The texture image loading confronted an error.
Note
Properties can be used directly when
from __feature__ import true_property
is used or via accessor functions otherwise.- property mirroredᅟ: 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 GPU compressed texture formats.
Warning
This property results in a performance price payed at runtime when loading uncompressed or CPU compressed image formats such as PNG. To avoid this performance price it is better to set this property to false and load texture assets that have been pre-mirrored.
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.
- Access functions:
This property holds the source url from which data for the texture image will be loaded.

- property statusᅟ: Qt3DRender.QTextureImage.Status¶
This property holds the status of the texture image loading.

- __init__([parent=None])¶
- Parameters:
parent –
QNode
Constructs a new
QTextureImage
instance withparent
as parent.- isMirrored()¶
- Return type:
bool
Returns whether mirroring is enabled or not.
Getter of property
mirroredᅟ
.- mirroredChanged(mirrored)¶
- Parameters:
mirrored – bool
Notification signal of property
mirroredᅟ
.- setMirrored(mirrored)¶
- Parameters:
mirrored – bool
Sets mirroring to
mirrored
.Note
This internally triggers a call to update the data generator.
