我有以下测试代码,我尝试用圆圈剪辑 MeshView。我还尝试将 meshView 放入一个组中,然后对其进行剪辑,但这会导致一个黑色圆圈。
有没有办法剪辑一个MeshView,最好不要把它放到一个组中?

val clipCircle = Circle(150.0)
val meshView = new MeshView(new RectangleMesh(500,500)) {
// takes a while to load
material = new PhongMaterial(Color.White, new Image("https://peach.blender.org/wp-content/uploads/bbb-splash.png"), null, null, null)
}
// val meshGroup = new Group(meshView)
meshView.setClip(clipCircle)
root = new Group {children = meshView; translateX = 250.0; translateY = 250.0; translateZ = 560.0}
camera = new PerspectiveCamera(false)
}
}
