详细描述

Texture defines an image and how it is mapped to meshes in a 3d scene.

Texture components can use image data either from a file using the source property, or a Qt Quick item using the sourceItem 特性。

flipV : bool

This property sets the use of the vertically flipped coordinates.

format : enumeration

This property controls the color format of the texture assigned in source 特性。

By default, it is automatically determined. However, it can be manually set if the automatic format is not what is wanted.

常量	描述

Texture.RG8	The color format is considered as 8-bit integer in R and G channels.
Texture.RGBA8	The color format is considered as 8-bit integer in R, G, B and alpha channels.
Texture.RGB8	The color format is considered as 8-bit integer in R, G and B channels.
Texture.SRGB8	The color format is considered as 8-bit integer in R, G and B channels in standard RGB color space.
Texture.SRGB8A8	The color format is considered as 8-bit integer in R, G, B and alpha channels in standard RGB color space.
Texture.RGB565	The color format is considered as 5-bit integer in R and B channels and 6-bit integer in G channel.
Texture.RGBA5551	The color format is considered as 5-bit integer in R, G, B channels and boolean alpha channel.
Texture.Alpha8	The color format is considered as 8-bit alpha map.
Texture.Luminance8	The color format is considered as 8-bit luminance map.
Texture.Luminance16	The color format is considered as 16-bit luminance map.
Texture.LuminanceAlpha8	The color format is considered as 8-bit luminance and alpha map.
Texture.RGBA16F	The color format is considered as 16-bit float in R,G,B and alpha channels.
Texture.RG16F	The color format is considered as 16-bit float in R and G channels.
Texture.RG32F	The color format is considered as 32-bit float in R and G channels.
Texture.RGB32F	The color format is considered as 32-bit float in R, G and B channels.
Texture.RGBA32F	The color format is considered as 32-bit float in R, G, B and alpha channels.
Texture.R11G11B10	The color format is considered as 11-bit integer in R and G channels and 10-bit integer in B channel.
Texture.RGB9E5	The color format is considered as 9-bit mantissa in R, G and B channels and 5-bit shared exponent.
Texture.RGBA_DXT1	The color format is considered as DXT1 compressed format with R, G, B and alpha channels.
Texture.RGB_DXT1	The color format is considered as DXT1 compressed format with R, G and B channels.
Texture.RGBA_DXT3	The color format is considered as DXT3 compressed format with R, G, B and alpha channels.
Texture.RGBA_DXT5	The color format is considered as DXT5 compressed format with R, G, B and alpha channels.
Texture.Depth16	The color format is considered as 16-bit depth map.
Texture.Depth24	The color format is considered as 24-bit depth map.
Texture.Depth32	The color format is considered as 32-bit depth map.
Texture.Depth24Stencil8	The color format is considered as 24-bit depth and 8-bit stencil map.

mappingMode : enumeration

This property defines which method of mapping to use when sampling this texture.

常量	描述
Texture.UV	The default for diffuse and opacity maps, this causes the image to be stuck to the mesh. The same portion of the image will always appear on the same vertex (unless the UV properties are animated).
Texture.Environment	The default for specular reflection, this causes the image to be ‘projected’ onto the material as though it is being reflected. Using Environmental Mapping for diffuse maps provides a mirror effect.
Texture.LightProbe	The default for HDRI sphere maps used by light probes.

pivotU : float

This property sets the pivot U position.

pivotV : float

This property sets the pivot V position.

另请参阅 rotationUV .

positionU : float

This property offsets the U coordinate mapping from left to right.

positionV : float

This property offsets the V coordinate mapping from bottom to top.

rotationUV : float

This property rotates the texture around the pivot point. This is defined using euler angles and for a positve value rotation is clockwise.

另请参阅 pivotU and pivotV .

scaleU : float

This property defines how to scale the U texture coordinate when mapping to a mesh's UV coordinates.

Scaling the U value when using horizontal tiling will define how many times the texture is repeated from left to right.

另请参阅 tilingModeHorizontal .

scaleV : float

This property defines how to scale the V texture coordinate when mapping to a mesh's UV coordinates.

Scaling the V value when using vertical tiling will define how many times a texture is repeated from bottom to top.

另请参阅 tilingModeVertical .

source : url

This property holds the location of an image file containing the data used by the texture.

另请参阅 sourceItem .

sourceItem : Item

This property defines a Item to be used as the source of the texture. Using this property allows any 2D Qt Quick content to be used as a texture source by renderind that item as an offscreen layer.

If this property is used, then the value of source 将被忽略。

注意： Currently there is no way to forward input events to the Item used as a texture source.

tilingModeHorizontal : enumeration

Controls how the texture is mapped when the U scaling value is greater than 1.

常量	描述
Texture.ClampToEdge	Texture is not tiled, but the value on the edge is used instead.
Texture.MirroredRepeat	Texture is repeated and mirrored over the X axis.
Texture.Repeat	Texture is repeated over the X axis.

tilingModeVertical : enumeration

This property controls how the texture is mapped when the V scaling value is greater than 1.

常量	描述
Texture.ClampToEdge	Texture is not tiled, but the value on the edge is used instead.
Texture.MirroredRepeat	Texture is repeated and mirrored over the Y axis.
Texture.Repeat	Texture is repeated over the Y axis.
