Qt Graphs Integration with Qt Quick 3D

As Qt Graphs for 3D is based on Qt Quick 3D, it is possible to integrate Qt Quick 3D scenes into the graphs.

Scene Environment

Adjusting a Qt Quick 3D scene environment in a graph requires defining either SceneEnvironment or ExtendedSceneEnvironment 在 environment property of the graph as follows:

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
}

Non-supported Features

Overriding anti-aliasing mode or scene clear color do not work, which means that setting value for SceneEnvironment.antialiasingMode and SceneEnvironment.clearColor does nothing. However, if the backgroundMode 不是 SceneEnvironment.Color , background will be affected by the settings.

Scene Integration

Integrating a Qt Quick 3D scene into a graph requires setting a Node 到 importScene property of the graph as follows:

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
            }
        ]
    }
}
