“…As can be seen from the analysis Figure 7, the detection accuracy of the collision in the scene simulation using three methods is not the same. When the number of simulation scenes is 2, the detection accuracy of this method is about 81%, that of Yoder et al (2018) method is about 67%, and that of Levac (2017) method is about 49%. When the number of simulation scenes is 8, the detection accuracy of this method is about 98%, that of Yoder et al (2018) method is about 90%, and that of Levac (2017) method is about 88%.…”

“…In Yoder et al (2018), aiming at the problem that most of the existing physical based fluid algorithms are only suitable for small-scale scenes, and it is difficult to effectively simulate the effect of solid-liquid coupling in large-scale complex fluid scenes, an efficient solid-liquid coupling simulation method for complex scenes is proposed. Firstly, a hybrid calculation framework based on the implicit particle method and the SPH method with zero divergence is proposed, At the same time of ensuring the physical properties of the fluid, we make full use of the fine-grained implicit particles to enrich the details of the fluid movement and improve the reality of the scene simulation; then we use a multi-dimensional fluid solid coupling separation and combination calculation strategy to improve the efficiency of the fluid solid coupling; in order to achieve the solid crushing effect under the impact of the fluid, A method of physical and geometric mixing is adopted: the distribution of fragments is determined based on the strain energy density model in fracture mechanics, and the fragments are generated quickly by the geometric Voronoi method.…”

In view of the problems in traditional 3D scene simulation, such as the poor simulation effect and the inability to really feel the scene, this paper proposes the research of nano particle system scene construction based on virtual technology. By analyzing the advantages of virtual reality technology, the role of virtual reality in three-dimensional scene is determined; the method of three-dimensional geometry transformation is used to determine the scene building algorithm of virtual technology; the concept of nano particle system hierarchy is introduced to build nano particle subsystem with object-oriented concept. The functions of the system are mainly divided into system control module, user interaction module, scene management module, and nanoparticles management module. Based on the analysis of virtual technology and the construction of nano particle system, the construction of nano particle system scene based on virtual technology is realized. The experimental results show that: Based on the virtual technology, the nano particle system scene construction effect is better, and the scene construction time is less than 6 min, the work efficiency is higher, the scene is more realistic, and has a certain feasibility.
