Qt 图形与 Qt Quick 3D集成

由于Qt Graphs for 3D基于Qt Quick 3D，因此可以将Qt Quick 3D场景集成到图表中。

场景环境

调整图表中的Qt Quick 3D场景环境，需要在图表的environment属性中定义SceneEnvironment或ExtendedSceneEnvironment，如下所示

environment: ExtendedSceneEnvironment {
    aoEnabled: true
    aoDither: true
    ditheringEnabled: true
    lightProbe: Texture {
        textureData: ProceduralSkyTextureData {
            groundBottomColor: "black"
            skyTopColor: "white"
        }
    }
    backgroundMode: SceneEnvironment.SkyBox
    lensFlareEnabled: true
    lensFlareGhostCount: 10
    lensFlareApplyStarburstTexture: true
    lensFlareBloomBias: 0.4
}

不支持的功能

重写抗锯齿模式或场景清除颜色不起作用，这意味着为SceneEnvironment.antialiasingMode和SceneEnvironment.clearColor设置值没有任何效果。但是，如果backgroundMode不是SceneEnvironment.Color，则背景将受到设置的影响。

场景集成

将Qt Quick 3D场景集成到图表中需要在图表的importScene属性中设置一个Node，如下所示

importScene: Node {
    Model {
        scale: Qt.vector3d(0.01, 0.01, 0.01)
        source: "#Sphere"
        x: 2.5
        z: 2
        y: 1
        castsReflections: false
        receivesReflections: true
        materials: [
            PrincipledMaterial {
                baseColor: "gold"
                metalness: 1.0
                roughness: 0.1
            }
        ]
        ReflectionProbe {
            boxSize: Qt.vector3d(6, 3, 5)
            boxOffset: Qt.vector3d(-1.5, -1, -1.5)
            parallaxCorrection: true
            quality: ReflectionProbe.High
        }
    }
    Model {
        scale: Qt.vector3d(0.01, 0.01, 0.01)
        source: "#Sphere"
        x: -2.5
        z: -2
        y: 1
        castsReflections: false
        receivesReflections: true
        materials: [
            PrincipledMaterial {
                baseColor: "white"
                metalness: 0.0
                roughness: 0.0
                transmissionFactor: 1.0
                thicknessFactor: 50
            }
        ]
    }
}
