Due to development of computer graphics technology, entertainment industry has been widely applied for game, movie, Scenario-based 3D animation. And animation which is similar to real world appearing a number of characters is increased. 3D object motion is very important in computer animation such as movie, game etc. However, creating different motion on each character takes long time and high cost.Computer animation includes two parts; 3D model information and 3D motion information. 3D model is created by 3D modeling program, but there are three problems on the using of 3D modeling program to create 3D object motion. First, after edit the motion information, the file size would be increased than before. Second, 3D object motion only can be edited by 3D modeling program. Third, it takes long time and high cost to create motion information.The research is the implementation of modeler to solve three problems. This modeler can edit objects Attributes which is used animation and create Scenario which is expressed by motion.
