TextureImage QML Type

  • Import Statement: import Qt3D.Render 2.5

  • Inherits: AbstractTextureImage

  • Instantiates:: QTextureImage

Detailed Description

 

Property Documentation

 

face : enumeration

Holds the cube map face of the texture image.

Constant

Description

CubeMapPositiveX

0x8515 GL_TEXTURE_CUBE_MAP_POSITIVE_X

CubeMapNegativeX

0x8516 GL_TEXTURE_CUBE_MAP_NEGATIVE_X

CubeMapPositiveY

0x8517 GL_TEXTURE_CUBE_MAP_POSITIVE_Y

CubeMapNegativeY

0x8518 GL_TEXTURE_CUBE_MAP_NEGATIVE_Y

CubeMapPositiveZ

0x8519 GL_TEXTURE_CUBE_MAP_POSITIVE_Z

CubeMapNegativeZ

0x851A GL_TEXTURE_CUBE_MAP_NEGATIVE_Z

The cube map face has a meaning only for TargetCubeMap and TargetCubeMapArray.

layer : int

Holds the layer of the texture image.

mipLevel : int

Holds the mipmap level of the texture image.

mirrored : 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.

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.

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

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

source : url

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

[read-only] status : enumeration

This property holds the status of the texture image loading.
