Qt Quick 3D 物理——材料示例
演示如何使用物理材质。
“材质”示例演示了如何控制物理体的材质属性。该场景包含View3D 、PhysicsWorld 、PerspectiveCamera 和DirectionalLight 等常规组件。此外，场景中还包含两个物理体，即一个略微倾斜的平面和一个盒子。 每个物理体都具有一个名为 `physicsMaterial ` 的属性，该属性包含一个 `PhysicsMaterial ` 节点。`PhysicsMaterial ` 包含以下三个材质属性：staticFriction 、dynamicFriction 和restitution ，这些属性用于定义物理体在与其他物体碰撞和滑动时的行为。系统提供了一个简单的用户界面，允许用户交互式地调整方块的材质，以便观察其根据不同材质属性的交互效果。
以下是该材质的 QML 代码：
PhysicsMaterial {
id: physicsMaterial
staticFriction: staticFrictionSlider.value
dynamicFriction: dynamicFrictionSlider.value
restitution: restitutionSlider.value
}该材质仅引用了用户界面中滑块的数值。随后，该材质被同时应用于方块和地板：
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
}
