◆ QQuick3DTextureDataFrontend()

QT_BEGIN_NAMESPACE QQuick3DTextureDataFrontend::QQuick3DTextureDataFrontend ( )

\qmlproperty int ProceduralTextureData::width

\qmltype ProceduralTextureData
\inqmlmodule QtQuick3D.Helpers
\inherits TextureData
\brief Allows creation and population of TextureData from QML.
\since 6.6

ProceduralTextureData is a helper type that allows creation of TextureData from QML.
The TextureData component is Abstract, and is usually created from C++. With
ProceduralTextureData, it is possible to populate a TextureData from QML.

\qml
ProceduralTextureData {
    id: dynamicTextureData
    property color color1: "red"
    property color color2: "black"
    width: 32
    height: 32
    hasTransparency: false
    format: TextureData.RGBA8
    textureData: generateTextureData(color1, color2)

    function generateTextureData(newColor1: color, newColor2 : color) : ArrayBuffer {
        let dataBuffer = new ArrayBuffer(width * height * 4)
        let data = new Uint8Array(dataBuffer)

Create a checkered pattern using newColor1 and newColor2 for (let x = 0; x < width; x++) { for (let y = 0; y < height; y++) { let index = (x + y * width) * 4 let color = (x % 2 === y % 2) ? newColor1 : newColor2 data[index + 0] = color.r * 255 data[index + 1] = color.g * 255 data[index + 2] = color.b * 255 data[index + 3] = 255 } } return dataBuffer } } \endqml

In the above code snippet, the function generateTextureData is used to generate a checkerboard pattern using the two colors color1 and color2. By filling an ArrayBuffer with the generated data, the textureData property of the TextureData is populated.

This property holds the width of the texture data in pixels. \default 0

\qmlproperty int ProceduralTextureData::height

This property holds the height of the texture data in pixels. \default 0

\qmlproperty int ProceduralTextureData::depth

This property holds the depth of the texture data in pixels. \default 0 Setting the depth above 0 means that the texture is handled as a 3D texture.

\qmlproperty bool ProceduralTextureData::hasTransparency

This property holds whether the texture data has transparency.

\qmlproperty enumeration ProceduralTextureData::format

This property holds the format of the texture data.

\default TextureData.RGBA8

\value TexureData.None The color format is not defined \value TexureData.RGBA8 The color format is considered as 8-bit integer in R, G, B and alpha channels. \value TexureData.RGBA16F The color format is considered as 16-bit float in R,G,B and alpha channels. \value TexureData.RGBA32F The color format is considered as 32-bit float in R, G, B and alpha channels. \value TexureData.RGBE8 The color format is considered as 8-bit mantissa in the R, G, and B channels and 8-bit shared exponent. \value TexureData.R8 The color format is considered as 8-bit integer in R channel. \value TexureData.R16 The color format is considered as 16-bit integer in R channel. \value TexureData.R16F The color format is considered as 16-bit float in R channel. \value TexureData.R32F The color format is considered as 32-bit float R channel. \value TexureData.BC1 The color format is considered as BC1 compressed format with R, G, B, and alpha channels. \value TexureData.BC2 The color format is considered as BC2 compressed format with R, G, B, and alpha channels. \value TexureData.BC3 The color format is considered as BC3 compressed format with R, G, B, and alpha channels. \value TexureData.BC4 The color format is considered as BC4 compressed format with one color channel. \value TexureData.BC5 The color format is considered as BC5 compressed format with two color channels. \value TexureData.BC6H The color format is considered as BC6H compressed format with three high dynamic range color channels. \value TexureData.BC7 The color format is considered as BC7 compressed format with R, G, B, and alpha channels. \value TexureData.DXT1_RGBA The color format is considered as DXT1 compressed format with R, G, B and alpha channels. \value TexureData.DXT1_RGB The color format is considered as DXT1 compressed format with R, G and B channels. \value TexureData.DXT3_RGBA The color format is considered as DXT3 compressed format with R, G, B and alpha channels. \value TexureData.DXT5_RGBA The color format is considered as DXT5 compressed format with R, G, B and alpha channels. \value TexureData.ETC2_RGB8 The color format is considered as ETC2 compressed format for RGB888 data \value TexureData.ETC2_RGB8A1 The color format is considered as ETC2 compressed format for RGBA data where alpha is 1-bit. \value TexureData.ETC2_RGBA8 The color format is considered as ETC2 compressed format with RGBA8888 data. \value TexureData.ASTC_4x4 The color format is considered as ASTC compressed format with 4x4 block footprint. \value TexureData.ASTC_5x4 The color format is considered as ASTC compressed format with 5x4 block footprint. \value TexureData.ASTC_5x5 The color format is considered as ASTC compressed format with 5x5 block footprint. \value TexureData.ASTC_6x5 The color format is considered as ASTC compressed format with 6x5 block footprint. \value TexureData.ASTC_6x6 The color format is considered as ASTC compressed format with 6x6 block footprint. \value TexureData.ASTC_8x5 The color format is considered as ASTC compressed format with 8x5 block footprint. \value TexureData.ASTC_8x6 The color format is considered as ASTC compressed format with 8x6 block footprint. \value TexureData.ASTC_8x8 The color format is considered as ASTC compressed format with 8x8 block footprint. \value TexureData.ASTC_10x5 The color format is considered as ASTC compressed format with 10x5 block footprint. \value TexureData.ASTC_10x6 The color format is considered as ASTC compressed format with 10x6 block footprint. \value TexureData.ASTC_10x8 The color format is considered as ASTC compressed format with 10x8 block footprint. \value TexureData.ASTC_10x10 The color format is considered as ASTC compressed format with 10x10 block footprint. \value TexureData.ASTC_12x10 The color format is considered as ASTC compressed format with 12x10 block footprint. \value TexureData.ASTC_12x12 The color format is considered as ASTC compressed format with 12x12 block footprint.

Note: With the exception of TexureData.RGBA8, not every format is supported at runtime as this depends on which backend is being used as well which hardware is being used.; TexureData.RGBE is internally represented as an TexureData.RGBA8 but is interpreted as described when used as a lightProbe or skybox texture.; Using the value TexureData.None will assume the default value of TexureData.RGBA8

\qmlproperty ArrayBuffer ProceduralTextureData::textureData

This property holds the texture data.
