* @brief obtain the reconstructed real-size shape using c parameters and t parameters
* @param c Input -- PCA appearance parameters, including both shape non-rigid variance + texture variance
* @param t Input -- parameters required for global shape normalization, rigid variance, refer to "AAM Revisited equation (42)"
* @param modelAlignedShape Output -- the modeled aligned shape
* @param modelNormalizedTexture Output -- the modeled normalized texture
* @param oShape Output -- output shape after global shape normalization. Please make sure global shape normalization is not Procrustes Analysis.
* @param scale Input and Output -- scaling
* @param rotateAngles Input and Output -- rotation
* @param matCOG Input and Output -- translation
