Research on STK-Based 3D Model Transformation and Optimization

It is necessary to establish a 3D model with vivid effects in order to improve human–computer interaction (HCI) efficiency in the field of operation simulation. Based on the particularity of the 3D model format in the Satellite Tool Kit (STK)/VO module, this paper analyzes the data structure of the STK 3D model, describes how to directly acquire the model in MDL format, and analyzes its shortcomings and deficiencies. Taking the common 3D modeling software 3DMax as an example, this paper focuses on the description of how to transform 3D models in different formats into MDL models and subsequently forms a model solution for STK software to achieve high complexity, streamlined structure data, and vivid lighting effects during mission simulation, including the model transformation process, geometry data optimization of the model, and optimization solutions in model transformation. Practice has proven that the proposed method offers effective optimization and more vivid effects and can greatly improve the efficiency and effectiveness of HCI.
