Problems solved by technology
[0003] The slings or cables in the virtual simulation system belong to the simulation of linear flexible objects. The existing research results on flexible ropes have problems of poor real-time and fidelity. Among them, the model that is more suitable for the physical characteristics of flexible ropes is the honeycomb structure model. The simulation effect is more realistic, but the curvature between each particle layer cannot be effectively limited, and the phenomenon of two particle layers bending 180 is prone to occur. To solve this problem, the present invention improves its model to improve the physical reality of the model

An improved method of honeycomb flexible rope truthfulness in virtual simulation is characterized in that the method comprises the steps of: 1) establishing a honeycomb particle of the flexible rope through a plurality of hexagonal columns surrounding the honeycomb particle-spring model; 2) based on the honeycomb particle-spring model, distributing the mass of flexible rope is distributed uniformly on the mass point, wherein the mass point is connected with the mass point by many kinds of springs. Different elastic coefficients and damping coefficients are set for different types of springs tosimulate the internal forces in different directions of the rope. A limit bending spring is added between the central mass points between each alternate mass point layer to limit the abnormal phenomenon of bending 180 degree between adjacent mass point layers, and the accuracy of the model and the simulation reality are improved.
Description
technical field [0001] The invention relates to the processing of a virtual simulation system, in particular to a method for improving the realism of a honeycomb flexible rope in virtual simulation. Background technique [0002] Virtual simulation: Simulation technology, or simulation technology, is the technology of using one system to imitate another real system. A virtual simulation is actually a computer system that creates and experiences virtual worlds. This kind of virtual world is generated by computer, which can be a reproduction of the real world or an imaginary world. Users can interact naturally with the virtual world through various sensory channels such as vision, hearing and touch. It creates a three-dimensional virtual world that reflects the changes and interactions of physical objects in real time for users in a simulated way, and provides users with a three-dimensional interface for observing and interacting with the virtual world through auxiliary sensin...
