OGRE engine-based large ship diesel main engine virtual reality system

Abstract

The invention discloses an OGRE engine-based large ship diesel main engine virtual reality system. The system comprises a model building unit and a collision detection unit. The model building unit acquires target diesel main engine parameters and related real ship parameters, and builds a three-dimensional simulation model of a ship diesel main engine. The collision detection unit calls the three-dimensional simulation model, receives the three-dimensional simulation model as a dynamic moving object and a static environment object, calculates intersection situations of hierarchical bounding boxes of other models of ray sections in combination with a model running distance by constructing the ray sections of the vertexes of models possibly generating motion conflicts in the dynamic moving object, and judging whether part models in the current dynamic moving object, the dynamic moving object and the environment object are collided or not. The purposes of simulating ship driving and controlling a ship in an engine room are achieved. The system is high in integration level and good in expansibility due to modular design; and the system can be applied to development operation of other main engine simulators as long as corresponding field models are built and functions are slightly modified.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, in particular to an OGRE engine-based virtual reality system for a large ship diesel engine. Background technique [0002] In recent years, with the continuous development of virtual reality (VR) technology, using virtual reality technology and computer simulation technology to establish a multi-mode virtual environment with hearing, vision and touch, with the help of virtual reality input and output devices, designers Human-computer interaction can be carried out in a virtual environment.

[0003] Due to the construction and use of the physical test platform, regardless of the utilization rate of the test platform, a large amount of water, electricity, diesel and other resources will be consumed, and certain equipment depreciation, repair, maintenance and environmental governance costs will be generated.

When it is necessary to verify some new schemes and new equipment, the physical test platform must purchase a large number of new equipment, which is expensive and has a long procurement cycle, and there are certain technical risks in the application of new technologies. Once a problem occurs, it is easy to cause equipment damage. damage
