A Simulation Implementation Method of Filling and Mining

Abstract

The invention discloses a simulation realization method for cut and fill. The simulation realization method comprises the following steps: organizing whole spatial data by adopting a top-down layered tree structure to construct a scene graph of mine cut and fill simulation; carrying out three types of traversal operation to the constructed scene graph, wherein the three types of traversal operation are respectively updating, selecting and drawing; on the basis of the constructed scene graph, adopting an intersection test mesh deformation technology to simulate a cutting coal wall change process of a coal mining machine in a coal mining process, simulating by adopting a particle system by aiming at the falling of coal granules; and on the basis of the constructed scene graph, carrying out simulation realization to pipeline flowing and space filling effect in a filling animation. The real-time rendering speed of the system can be quickened, the motion control of the complex motion of coal mining equipment is solved, coal falling special effects and a filling simulation solution in a coal cutting scene are provided so as to improve a coal mining rate and a use ratio.

Description

Technical field [0001] The invention relates to the field of three-dimensional simulation technology, and in particular to a simulation realization method of filling mining. Background technique [0002] At present, with the increasing acceleration of the informatization process of the mining industry, research staff at home and abroad have begun to experimentally apply virtual reality technology in the field of mining. In developed countries with a relatively high degree of mining automation and informatization, such as Germany, France, the United States, Australia, Canada and South Africa, the earliest attempts to apply 3D visualization technology to the field of mining, the above technologies all involve scene organization, texture mapping, and particle systems And other key technologies. [0003] In order to facilitate the development of 3D graphics applications and optimize graphics performance, the concept of scene graphs was created. The scene database contains the geometr...

However, since Virtools does not provide menu functions, it takes a lot of energy to develop the user interface. When the number of models increases, the rendering speed of the system will drop severely, and the complex logic control will also reduce the display frame rate.
