Qt Quick 3D - 细节级别辅助工具示例

演示了细节级别(LOD)助手的使用方法。

带有不同细节等级实例化对象的半身像雕塑

本示例演示了 LODManager 辅助工具的使用方法。LODManager 通过根据与指定摄像机的距离来更改其节点子节点的可见性来工作。distances 属性是一个距离阈值列表,用于确定何时更改子节点的可见性。当距离最近时显示第一个子节点,当距离最远时显示最后一个子节点。

LodManager {
    camera: camera
    distances: [100, 140, 180]
    fadeDistance: 10

    Model {
        scale: Qt.vector3d(100, 100, 100);
        source: "meshes/marble_bust_01_LOD_0.mesh"
        materials: [ marbleMaterial ]
    }

    Model {
        scale: Qt.vector3d(100, 100, 100);
        source: "meshes/marble_bust_01_LOD_1.mesh"
        materials: [ marbleMaterial ]
    }

    Model {
        scale: Qt.vector3d(100, 100, 100);
        source: "meshes/marble_bust_01_LOD_2.mesh"
        materials: [ marbleMaterial ]
    }

    Model {
        scale: Qt.vector3d(100, 100, 100);
        source: "meshes/marble_bust_01_LOD_3.mesh"
        materials: [ marbleMaterial ]
    }
}
