With the development of China 's digital entertainment industry , as online games core game engine technology , especially in the study of the 3D game engine is very valuable . As the most important external characteristics of the face , plays a very important role in a person - to - person communication in the exchange process . It is able to pass the many non-verbal information to enhance understanding and emotional expression , and thus become the key of the game character modeling technology , general face model of the specific subject to the attention of more and more companies in the gaming scene . In order to meet the requirements of the personalized game character modeling accuracy and efficiency must be balanced , the paper design a a photo personalized face game engine . Its main work includes the following aspects : 1 . Designed to face the main structure of the game engine . Defined for the game and can effectively support personalized deformation and real-time display of three-dimensional neutral face model data structure . Method based on orthogonal photos personalized the game human face shape , using two orthogonal face the positive side of the photo synthetic 3D face . First given in the photo of the front and side of the face reflect the face shape features extracted feature points , and then these feature points using radial basis function interpolation method to deform the neutral face model to a specific face model . Photorealistic rendering of personalized face model under different illumination face model and texture model . Positive side photo face texture information on a specific face model , texture mapping, and eventually get a realistic virtual 3D face . Using a feature constraint - based real-time continuous multi-resolution drawing methods to draw models to meet the real-time rendering requirements of the game .
