| Abstract: CHAI3D has powerful force-sensing rendering capabilities, but its related applications are not extensive. In view of this problem, this paper proposes to build a virtual surgical scene on the CHAI3D platform. The 3ds files of operating table and human body are imported, and visual representation of the system is enhanced through attribute setting, texture mapping, and perspective transformation. This paper elaborates the specific process of virtual surgical scene design on CHAI3D platform and the force rendering advantage of CHAI3D in virtual training system. Finally, virtual surgical training system from different perspectives is presented. The key program segments and training system examples fully reflect the convenience and efficiency of CHAI3D in the creation of virtual reality scenes and human-computer interaction, and the proposed system provides a reference for beginners to get started quickly. |
