 Flags::RequiresSecondaryUpdate indicates that the object needs a secondary update, meaning an additional call to updateSpatialNode() will be made after the first one.

Constructor & Destructor Documentation

◆ QQuick3DTextureProviderExtensionPrivate()

QQuick3DTextureProviderExtensionPrivate::QQuick3DTextureProviderExtensionPrivate ( )

\qmlproperty enumeration TextureProviderExtension::samplerHint

This property contains a hint about the type of texture that will be provided by the extension. This is necessary because the texture data will not be provided until it is necessary, but materials that use the Texture component need to know what type of sampler to provide. This property should be set to one of the following values:

\value TextureProviderExtension.Sampler2D The texture will be a 2D texture. \value TextureProviderExtension.Sampler2DArray The texture will be an array texture. \value TextureProviderExtension.Sampler3D The texture will be a 3D texture. \value TextureProviderExtension.SamplerCube The texture will be a cube map texture. \value TextureProviderExtension.SamplerCubeArray The texture will be an array of cube map textures. \value TextureProviderExtension.SamplerBuffer The texture will be a buffer texture.

The default value is TextureProviderExtension.Sampler2D.

Note
This property is only used when using CustomMaterials.
