away3d4.0中提供的建模指令LinearExtrude

用过三维造型建模软件的童鞋们肯定指导拉伸（挤压）这个指令（操作），away3d4..0也提供了这样一个类，其构造函数调用格式如下：

LinearExtrude(material:MaterialBase = null, vectors:Vector.<Vector3D> = null, axis:String, offset:Number = 10, subdivision:uint = 3, coverAll:Boolean = false, thickness:Number = 0, thicknessSubdivision:uint = 3, materials:MultipleMaterials = null, centerMesh:Boolean = false, closePath:Boolean = false, ignoreSides:String, flip:Boolean = false)

参数表：（原文貌似有点错位，做了些修改，望指正）

Parameters

	material:MaterialBase (default = null)
	vectors:Vector.<Vector3D> (default = null) — [optional]
	axis:String (default = NaN) — [optional]String. The axis to elevate along: X_AXIS, Y_AXIS or Z_AXIS. Default is LinearExtrusion.Y_AXIS.
	offset:Number (default = 10) — [optional] Number. The elevation offset along the defined axis.
	subdivision:uint (default = 3) — [optional] uint. The subdivision of the geometry between 2 vector3D. Default is 3.
	coverAll:Boolean (default = false) — [optional] Boolean. The way the uv mapping is spreaded across the shape. True covers an entire side of the geometry while false covers per segments. Default is false.
	thickness:Number (default = 0) — [optional] Number. If the shape must simulate a thickness. Default is 0.
	thicknessSubdivision:uint (default = 3) — [optional]uint. If thickness is higher than 0. Defines the subdivision of the thickness (top, left, right, bottom). Default is 3;
	materials:MultipleMaterials (default = null) — [optional]MultipleMaterials. Allows multiple material support when thickness is set higher to 1. Default is null. properties as MaterialBase are: bottom, top, left, right, front and back.
	centerMesh:Boolean (default = false) — [optional] Boolean. If the geometry needs to be recentered in its own object space. If the position after generation is set to 0,0,0, the object would be centered in worldspace. Default is false.
	closePath:Boolean (default = false) — [optional] Boolean. Defines if the last entered vector needs to be linked with the first one to form a closed shape. Default is false.
	ignoreSides:String — [optional] String. To prevent the generation of sides if thickness is set higher than 0. To avoid the bottom ignoreSides = "bottom", avoiding both top and bottom: ignoreSides = "bottom, top". Strings options: bottom, top, left, right, front and back. Default is "".
	flip:Boolean (default = false)[optional] Boolean. If the faces must be reversed depending on Vector3D's orientation. Default is false.
