How to remove custom shape ?

[luckyxutao]

very thanks

 document.addEventListener("DOMContentLoaded", function () {
        stage = new NGL.Stage("viewport", { background: "#000" });
        // Code for example: component/shape-buffer

        var shape = new NGL.Shape("shape", { dashedCylinder: true })
        shape.addMesh(
          [ 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 1, 0, 1, 0, 0, 0, 1 ],
          [ 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0 ],
          undefined, undefined, "My mesh"
        )
        shape.addSphere([ 0, 0, 9 ], [ 1, 0, 0 ], 1.5)
        shape.addSphere([ 12, 5, 15 ], [ 1, 0.5, 0 ], 1)
        shape.addEllipsoid([ 6, 0, 0 ], [ 1, 0, 0 ], 1.5, [ 3, 0, 0 ], [ 0, 2, 0 ])
        shape.addCylinder([ 0, 2, 7 ], [ 0, 0, 9 ], [ 1, 1, 0 ], 0.5, "My Cylinder")
        shape.addCone([ 0, 2, 7 ], [ 0, 3, 3 ], [ 1, 1, 0 ], 1.5)
        shape.addArrow([ 1, 2, 7 ], [ 30, 3, 3 ], [ 1, 0, 1 ], 1.0)
        shape.addArrow([ 2, 2, 7 ], [ 30, -3, -3 ], [ 1, 0.5, 1 ], 1.0)
        shape.addBox([ 23, 1, 2 ], [ 0, 1, 0 ], 2, [ 0, 1, 1 ], [ 1, 0, 1 ])
        shape.addTetrahedron([ 27, 0, 1 ], [ 0, 1, 0 ], 2, [ 0, 1, 1 ], [ 1, 0, 1 ])
        shape.addOctahedron([ 8, 5, 14 ], [ 0, 1, 0 ], 2, [ 0, 1, 1 ], [ 1, 0, 1 ])
        shape.addTorus([ 16, 5, 14 ], [ 0, 1, 0 ], 2, [ 0, 1, 1 ], [ 1, 0, 1 ])
        shape.addText([ 15, -4, 4 ], [ 0.2, 0.5, 0.8 ], 2.5, "Hello")

        var shapeComp = stage.addComponentFromObject(shape)
        shapeComp.addRepresentation("buffer")
        shapeComp.autoView()

stage.removeComponent(shapeComp)
