Abstract: The training of petrochemical employees uses the model of classroom and book teaching with stereotyped content and single pattern. This training form has many deficiencies，such as loss of interest and puny abilities. With the aim of resolving the problems，a new scheme based on interactive environment was proposed. The system built the enterprise three-dimensional scene model，used inverse kinematics algorithm to resolve the data glove of interaction in scene，and a three-dimensional rendering acceleration method based on the idea of graphic processing unit was introduced. The three-dimension training system was developed based on virtual reality engine. The training made use of multimedia computer system to provide cognition cultivation，used human-computer interaction to enhance operation level，and evaluated performance by assessment modules. Finally，experimental results demonstrated that the system could help users master the operation and emergency treatment much better than traditional training and was approved by the enterprise.
