With the development of digitalization in various fields, the water conservancy field is gradually developing digital three-dimensional visualization research to promote the development of digital watershed construction. This paper deeply analyzes and discusses the theory and application of three-dimensional visualization of river water scenes and realizes an interactive visual simulation system based on virtual reality technology, which simulates simulation and operation management, which can greatly accelerate the data. The processing speed makes the huge data be effectively utilized to provide visual interaction means for numerical simulation and data analysis, improve the efficiency of numerical calculation, and realize human-computer interaction communication, so that people can observe the phenomena and laws that are difficult to observe by traditional methods. The rationality of the mathematical model is analyzed for effectiveness.

To simulate arbitrary three dimensional models, this technology of triangular polyhedron 3D human-computer interaction modeling was proposed. Achieving the technology has following three steps. Firstly, the coordinates of 3D nodes were projected onto the plane by the method of 3D geometric transformation. Then, this information which was made up of triangles and sides and nodes was picked up by 3D picking methods. Finally, the technique of rubber membrane was used to modify the nodes of triangles, and the 3D modification was achieved by means of anti-transformation. Moreover, the method of global and local mesh encryption was also designed to modify 3D topology structure, which was aimed at better simulate complex 3D models. This technology combined geophysical forwarding compute and formed the method of data-interaction simulation, which provided a means of visualization for geophysical data interpretation.

The three-dimensional virtual reality technology was introduced into the visualized substation. The virtual substation models of main electrical equipment and the whole scene were built by using 3dsMax modeling software. After the design of special events response routing and editting the corresponding script language, users can interact with virtual objects in the scene model, resulting in feelings and experiences on the ground. Compared with the real substation, the virtual substation has the advantages of low cost, interactive operation safety, and is of great significance to improve the technical level of the operators.

With the continuous development and progress of virtual reality technology in recent years, the application of virtual reality technology in all aspects of real life is no longer limited to the military field, medical, or film production fields, but it gradually appears in front of the public, into the lives of ordinary people. The human-computer interaction method in virtual reality and the presentation effect of the virtual scene are the two most important aspects of the virtual reality experience. How to provide a good human-computer interaction method for virtual reality applications and how to improve the final presentation effect of the virtual reality scene is also becoming an important research direction. This paper takes the virtual fitness club experience system as the application background, analyzes the function and performance requirements of the virtual reality experience system in the virtual reality environment, and proposes the use of Kinect as a video acquisition device to extract the user’s somatosensory operation actions through in-depth information to achieve somatosensory control. This article adopts a real human-computer interaction solution, uses Unity 3D game engine to build a virtual reality scene, defines shaders to improve the rendering effect of the scene, and uses Oculus Rift DK2 to complete an immersive 3D scene demonstration. This process greatly reduces resource consumption; it not only enables users to experience unprecedented immersion as users but also helps people create unprecedented scenes and experiences through virtual imagination. The virtual fitness club experience system probably reduces resource consumption by nearly 70%.

The Mathematical Model

The three-dimensional figure of a toroidal worm is obtained according the simulation based on the mathematical model. The key of this is the authenticity of the worm surface expressed. Comparing a simulating worm with the true worm, the conformational degree between them can be found out. As the worm surfaces are complex space surfaces, so it is difficult to determine the measuring method and reference for the surfaces of a worm. According to the entire analysis's, the symmetry section of the worm is defined as a representing section. The space surface measuring is converted to a plane curve measuring, and the possibly existing error will be analyzed. The experiments for checking two true worms are made to prove the truthfulness and reliability of the simulation program of the plane enveloping toroidal worm.
