摘要： Disclosed herein is a method and system for transforming the muscles of a character model. The muscles of a target model are created using the muscle information of a reference model. The system includes a reference model processor and a target model processor. The reference model processor creates a reference feature volume, that is, a 3D geometric shape, based on the skeleton and appearance information of the reference model, and subordinates the muscle information of the reference model to the feature volume. The target model processor deforms the reference feature volume to be suitable for the target model, and applies the muscle information of the reference model to the target model, thereby creating muscles for the target model based on the extent of the deformation of the reference feature volume.
