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 PySide2.Qt3DRender.Qt3DRender.QTextureImage([parent=None])

Constructs a new QTextureImage instance with parent as parent.

PySide2.Qt3DRender.Qt3DRender.QTextureImage.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.
PySide2.Qt3DRender.Qt3DRender.QTextureImage.isMirrored()
Return type:

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 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.

PySide2.Qt3DRender.Qt3DRender.QTextureImage.mirroredChanged(mirrored)
Parameters:
