Where ever you move the corners\n * the texture will be projected to look like it is in 3d space. Great for mapping a 2D mesh into a 3D scene.\n *\n * The calculations is done at the uv level. This means that the more vertices you have the more smooth\n * the perspective will be. If you have a low amount of vertices you may see the texture stretch. Too many vertices\n * could be slower. It is a balance between performance and quality! We leave that to you to decide.\n *\n * IMPORTANT: This is not a full 3D mesh, it is a 2D mesh with a perspective projection applied to it :)\n * @example\n * ```js\n * const meshPlane = new PerspectiveMesh({\n *  texture: Texture.from('snake.png'),\n *  verticesX: 20,\n *  verticesY: 20,\n *  x0: 0,\n *  y0: 0,\n *  x1: 100,\n *  y1: 0,\n *  x2: 100,\n *  y2: 100,\n *  x3: 0,\n *  y3: 100\n * });\n * @see {@link scene.PerspectiveMesh}\n * @memberof scene\n */\nexport class PerspectiveMesh extends Mesh<PerspectivePlaneGeometry>\n{\n    /** default options for the mesh */\n    public static defaultOptions: PerspectivePlaneOptions = {\n        texture: Texture.WHITE,\n        verticesX: 10,\n        verticesY: 10,\n        x0: 0,\n        y0: 0,\n        x1: 100,\n        y1: 0,\n        x2: 100,\n        y2: 100,\n        x3: 0,\n        y3: 100\n    };\n\n    /**\n     * @param options -
