可以快速的导出Maya的mesh到wrl格式(For my GF)

例如，上图Tshape所导出wrl为：

#VRML V2.0 utf8 (Converted to ASCII)
#Exported from Maya by SU&WEI
Shape {
	geometry IndexedFaceSet {
		coord Coordinate {
			point [
			-0.5  -0.5  0.5  -1
			0.5  -0.5  0.5  -1
			-0.5  0.5  0.5  -1
			0.5  0.5  0.5  -1
			-0.5  0.5  -0.5  -1
			0.5  0.5  -0.5  -1

		}
		coordIndex [
