Since: Qt 5.5
Instantiated By: SkyboxEntity
Inherits: Qt3DCore::QEntity

This class was introduced in Qt 5.5.

Properties

Public Functions

QSkyboxEntity(Qt3DCore::QNode *parent = nullptr)
QString baseName() const
QString extension() const
bool isGammaCorrectEnabled() const

Public Slots

void setBaseName(const QString &baseName)
void setExtension(const QString &extension)
void setGammaCorrectEnabled(bool enabled)

Signals

void baseNameChanged(const QString &path)
void extensionChanged(const QString &extension)
void gammaCorrectEnabledChanged(bool enabled)

Detailed Description

By specifying a base name and an extension, Qt3DExtras::QSkyboxEntity will take care of building a TextureCubeMap to be rendered at runtime. The images in the source directory should match the pattern: base name + * "_posx|_posy|_posz|_negx|_negy|_negz" + extension

By default the extension defaults to .png.

Be sure to disable frustum culling in the FrameGraph through which the skybox rendering happens.

Note: Please note that you shouldn't try to render a skybox with an orthographic projection.
