详细描述

This helper type provides an easy way to generate a lightprobe/skybox texture in HDR format. Note that generating a lightprobe is an expensive process that can take significant time on embedded hardware.

The generated cubemap consists of three elements: the sky, the ground, and the sun. The sky and the ground cover the top and bottom hemispheres. The position of the sun can be specified by setting sunLatitude and sunLongitude .

        backgroundMode: SceneEnvironment.SkyBox
        lightProbe: Texture {

            }
        }
    }
}

特性文档编制

groundBottomColor : color

Specifies the ground color at the bottom of the skybox. The bottom half of the skybox has a gradient from groundHorizonColor to groundBottomColor .

groundCurve : real

Modifies the curve of the ground gradient.

groundEnergy : real

Specifies the intensity of the bottom half of the skybox. The ground gradient is multiplied with this factor.

groundHorizonColor : color

Specifies the ground color at the horizon. The bottom half of the skybox has a gradient from groundHorizonColor to groundBottomColor .

skyCurve : real

Modifies the curve of the sky gradient.

skyEnergy : real

Specifies the intensity of the top half of the skybox. The sky gradient is multiplied with this factor.

skyHorizonColor : color

Specifies the sky color at the horizon. The top half of the skybox has a gradient from skyHorizonColor to skyTopColor .

skyTopColor : color

Specifies the sky color at the top of the skybox. The top half of the skybox has a gradient from skyHorizonColor to skyTopColor .

sunAngleMax : real

Specifies the angle from the center of the sun to where it fades out completely.

sunAngleMin : real

Specifies the angle from the center of the sun to where it starts to fade.

sunColor : color

Specifies the color of the sun.

sunCurve : real

Modifies the curve of the sun gradient.

sunEnergy : float

Specifies the intensity of the sun.

sunLatitude : real

Specifies the angle between the horizon and the sun position.

sunLongitude : real

Specifies the angle between the forward direction and the sun position.

textureQuality : SkyTextureQuality

This property sets the quality of the sky texture. Supported values are:

常量	描述
`ProceduralSkyTextureData.SkyTextureQualityLow`	Generate a 512x512 texture
`ProceduralSkyTextureData.SkyTextureQualityMedium`	Generate a 1024x1024 texture
`ProceduralSkyTextureData.SkyTextureQualityHigh`	Generate a 2048x2048 texture
`ProceduralSkyTextureData.SkyTextureQualityVeryHigh`	Generate a 4096x4096 texture
