详细描述

使用 ExtendedSceneEnvironment 代替。

警告： All pre-made standalone effects in QtQuick3D .Effects are considered deprecated starting with Qt 6.5. To apply glow and bloom to the scene, use ExtendedSceneEnvironment 代替。

The HDRBloomTonemap effect provides two features:

• Adjusting the gamma and exposure of the high-dynamic range rendered content to achieve the image quality you want.
• Applying an adjustable bloom effect to bright areas (like the sun glinting off a car).

特性文档编制

bloomThreshold : real

Sets the threshold for the bloom effect. Any part of the scene brighter than this value will bloom. A value of 1.0 corresponds to white. Lowering this value causes more areas of the rendered scene to bloom. At a value of 0.0 everything in the scene blooms. The range is [0...1] 。默认值为 1 .

blurFalloff : real

Adjusts the amount of bloom. Lower values result in a stronger bloom effect, and higher values make the effect more subtle. The range is [0...10] 。默认值为 0 .

channelThreshold : real

Specifies the white point for the image. There is usually no need to adjust this. The range is [0...1] 。默认值为 1 .

exposure : real

Sets a linear multiplier on the lighting, brightening, or darkening the image overall. A value of 0.0 causes no adjustment to the image. The range is [-9...9] 。默认值为 0 .

gamma : real

Affects the non-linear curve of the lighting. Higher values increase the exposure of mid tones, lightening the image and decreasing the contrast. A value of 1.0 causes no adjustment to the image. Sensible values are in the range [0.1...4] 。默认值为 1 .

tonemappingLerp : real

Specifies the strength of the overall bloom effect. There is usually no need to adjust this. The range is [0...1] ，采用 0 being no blur and 1 being full bloom. The default value is 1 .
