Abstract


Computer-aided design and engineering applications to craniofacial plastic surgery program development process for doctors and patients to provide the visual image of the three-dimensional craniofacial reshaping effects . Analyze and summarize previous work based on in-depth study of craniofacial anatomical features , the organizational structure of the facial muscles , as well as the cheekbones anatomical structures , the geometric model of the three - dimensional craniofacial , and creatively put elastic deformation theory into the cranial to predict the state of the dough changes in the surface after shaping method . The article mainly includes the following aspects . . Use of craniofacial computer tomographic images (CT) reconstruction the craniofacial bones dough three-dimensional model , and simultaneously added lighting, material and other property , to achieve the realistic effect . By amplification of the three-dimensional model , pan , rotate, etc. , from any angle , the position of the graphics , and even some local details . 2 proposed a skinned mesh model based on the elastic deformation , using the model so that the dough can produce continuous deformation of the natural , to faithfully reproduce the craniofacial plastic effect . 3 . Deformation algorithms from the the craniofacial bone to the epidermis . The algorithm uses the minimum distance method reveals the relationship of craniofacial bone to the dough . Ideas on an algorithm to achieve the state of the forecast from the bone to the dough deformation finish shaping behind the cheekbones skin changes . Finally , using the above method combined with visual programming language Visual C + + and OpenGL graphics library craniofacial reshaping effects visualization .
