People have always longed for the virtual world, and the new information technology is also affecting the way people explore the virtual world. Since the emergence of VR technology, the form of entertainment has undergone tremendous changes. This technology has even penetrated into the film industry, causing some two-dimensional movies to be affected. At present, intelligent system technology is widely used in various industries, including aviation, aerospace, medical security and other fields. These fields have relatively high security requirements for intelligent systems, and the requirements will become higher and higher in the future. In order to have a better grasp of the security of the intelligent system, we modeled it and evaluated it through the model. In this research, we established a model of intelligent system by using computer language. This model mainly uses hierarchical modeling and proposes a method for reliability assessment of intelligent systems. In the process of implementation, we used Eclipse to design and formed a basic platform. We can evaluate the reliability of intelligent systems in a relatively short time on this platform, which is simpler than other methods and can save time. The validity of this study can be demonstrated by comparing the performance results with the expected results. Using this platform, we can model and evaluate some instances faster, and the results can be displayed visually. At the same time, we also explored how two-dimensional animated films should change their style.
