Abstract

The invention discloses a method for simulating work of a crane cable based on a game engine. The method comprises the following steps of: a, editing cable simulation relevant parameters in an off-line way; b, dynamically constructing physical models of a main cable and an auxiliary cable; and c, dynamically rendering a cable geometrical model to realize real simulation of the working state of the crane cable. Due to the adoption of the method for simulating work of the crane cable disclosed by the invention, real simulation of the working state of the crane cable can be realized, and the real-time reaction of the operation of a crane driver can be met; and the method has high expansibility, and is convenient to use. The method is based on a game engine Unity 3D; and in a platform, a most advanced graphics technology is adopted, a most popular physical engine PhysX is integrated, and the cost is low.

Description

technical field [0001] The invention relates to the fields of computer graphics and computer physics animation, in particular to a method for simulating crane sling work based on a game engine. Background technique [0002] The crane sling is the most important tool in the crane's work. The analysis and description of its motion characteristics has always been a difficult problem in the crane simulation and even in the design of the crane. In the study of the crane simulation training system, the real simulated working state of the crane sling plays a vital role in whether the training system can truly and efficiently train the crane operators. [0003] There are strict requirements for the simulation of the crane sling work in the simulation training system. Not only is the simulation required to be authentic and can completely simulate the real working conditions of the crane sling, but it is also required to be real-time and interactive, and the simulation can respond to ...
