mirrored : bool

This property specifies whether the texture 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.

警告: 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.

注意: OpenGL specifies the origin of texture coordinates from the lower left hand corner whereas DirectX uses the the upper left hand corner.

注意: When using cube map texture you'll probably want mirroring disabled as the cube map sampler takes a direction rather than regular texture coordinates.

QTextureLoader:: QTextureLoader ( Qt3DCore::QNode * parent = nullptr)

構造新的 Qt3DRender::QTextureLoader 實例與 parent 作為父級。

Note that by default, if not contradicted by the file metadata, the loaded texture will have the following properties set: - wrapMode set to Repeat - minificationFilter 設為 LinearMipMapLinear - magnificationFilter set to Linear - generateMipMaps set to true - maximumAnisotropy set to 16.0f - target set to TargetAutomatic

[slot] void QTextureLoader:: setMirrored ( bool mirrored )

Sets mirroring to mirrored .

注意: This internally triggers a call to update the data generator.

[slot] void QTextureLoader:: setSource (const QUrl & source )

Sets the texture loader source to source . source

注意: setter 函數對於特性 source .
