Qt Quick 3D Physics - 材料示例

演示如何使用物理材料。

材质示例演示了如何控制物理体的材质属性。场景包含View3D 、PhysicsWorld 、PerspectiveCamera 和DirectionalLight 等常用模板。此外，场景还包含两个物理体，即一个略微倾斜的平面和一个盒子。每个物理体都有一个包含PhysicsMaterial 节点的physicsMaterial 属性。PhysicsMaterial 包含三个材料属性：staticFriction 、dynamicFriction 和restitution ，这些属性用于定义物理体在与其他物理体碰撞和滑动时的动作。有一个简单的用户界面可以交互式地调整盒子的材料，这样你就可以看到它是如何根据材料属性进行交互的。

这是材料的 QML 代码：

PhysicsMaterial {
    id: physicsMaterial
    staticFriction: staticFrictionSlider.value
    dynamicFriction: dynamicFrictionSlider.value
    restitution: restitutionSlider.value
}

材质只是参考了用户界面滑块的值。盒子和地板都使用相同的材质：

DynamicRigidBody {
    id: box
    physicsMaterial: physicsMaterial
    massMode: DynamicRigidBody.CustomDensity
    density: 10
    property vector3d startPosition: Qt.vector3d(700, 300, 0)
    position: startPosition
    Model {
        source: "#Cube"
        materials: PrincipledMaterial {
            baseColor: "red"
        }
    }
    collisionShapes: BoxShape {}
}
StaticRigidBody {
    eulerRotation: Qt.vector3d(-79, -90, 0)
    scale: Qt.vector3d(20, 30, 100)
    physicsMaterial: physicsMaterial
    collisionShapes: PlaneShape {}
    Model {
        source: "#Rectangle"
        materials: PrincipledMaterial {
            baseColor: "green"
        }
        castsShadows: false
        receivesShadows: true
    }
}
