Embodiment Construction

[0019] The implementation of the present invention will be specifically described below.

[0020] In the three-dimensional virtual scene, the movement of objects under special conditions is simulated, and the method of the invention is suitable for virtual simulation of the hoisting process of tower legs in the construction process of transmission lines.

[0021] The main simulation directions include: the moving process of the tower legs, the continuous pulling of the rope by the motorized winch, in order to prevent the tower legs from colliding with the already assembled tower body during the moving process of the tower legs, there are staff at the end of the tower legs passing through the control rope and The motorized winch controls the horizontal distance between the tower legs and the tower body.

[0022] The movement methods include: the motorized winch slowly retracts and releases the hoisting rope, and the staff retracts and releases the control rope according to the ...

Abstract

Provided is a method for performing a three-dimensional virtual simulation transmission line tower group tower leg hoisting process. A three-dimensional engine renders all related scenarios. In the process of tower material rendering, the positions of two fixed points on a tower material are calculated according to the following method. Then, the central position and the orientation of the whole tower material are determined, and the position is determined by calculating each frame. Finally, intermediate interpolation is carried out to complete the smooth movement process of hoisting. The method of the invention is used under a three-dimensional virtual simulation condition. During virtual transmission line construction, virtual simulation using the algorithm is adopted in simulation of a tower leg hoisting process to enable the tower leg movement rule to be more in line with the actual situation and the hoisting process to be more realistic. The method of the invention is based on a three-dimensional rendering module and a script control module and is realized by the use of a physical engine of a DirectX. By adopting the method, tower leg movement can be controlled under an ordinary three-dimensional rendering condition.

Description

technical field [0001] The invention belongs to the technical field of computer three-dimensional simulation, is used for three-dimensional virtual simulation of the hoisting process of tower legs in the construction of power transmission lines, and is a method for three-dimensional virtual simulation of the hoisting process of tower legs of transmission line pole tower groups Background technique [0002] During the hoisting process of the tower leg in the construction process of the three-dimensional virtual simulation transmission line, when using the original physical engine to simulate the hoisting process of the tower leg in reality, because the calculation of the rigid body and the principle of object movement balance are not accurate enough, when the tower leg is hoisted, the rope pulls After a while, there will be shaking and jumping of the tower legs. In order to avoid this problem, the present invention proposes a new solution to specifically calculate the moving ...
