示例1: InverseTransform

 /**
  * returns the inverse of transformation matrix 
  * @readonly
  * @type {GLM.IArray}
  */
 public get InverseTransform(): GLM.IArray {
     if (this.mInverseTransVersion !== this.mVersion) {
         mat3.invert(this.mCachedInverse, this.mTransformation);
         this.mInverseTransVersion = this.mVersion;
     }
     //TODO should reset mIsTransformationDirty to false, maybe should also call an abstract function so children of this class can do some recalculations as well 
     return this.mCachedInverse;
