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:
property sourceᅟ: QUrl

This property holds the source url from which data for the texture image will be loaded.

Access functions:
property statusᅟ: Qt3DRender.QTextureImage.Status

This property holds the status of the texture image loading.

Access functions:
__init__([parent=None])
Parameters:

parentQNode

Constructs a new QTextureImage instance with parent 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.

isMirrored()

Setter of property mirroredᅟ .

setSource(source)
Parameters:

sourceQUrl

Sets the source url of the texture image to source.

Note

This internally triggers a call to update the data generator.

source()

Setter of property sourceᅟ .

setStatus(status)
Parameters:

statusStatus

Sets the status to status. status

status()

source()
Return type:

QUrl

Returns the source url from which data for the texture image will be loaded.

setSource()

Getter of property sourceᅟ .

sourceChanged(source)
Parameters:

sourceQUrl

Notification signal of property sourceᅟ .

status()
Return type:

Status

Returns the current status.

setStatus()

Getter of property statusᅟ .

statusChanged(status)
Parameters:

statusStatus

Notification signal of property statusᅟ .
