Application Of Parallel Volume Rendering Technology In Mine Engineering

The three-dimensional digital modeling of the ore body is one of the key technologies of the digital mine and the foundation for the realization of the digital mine.However,in practical engineering applications,it is difficult for the 3D modeling and visualization system of the ore body,especially the 3D visualization system based on the body mineralization model,to fully utilize its advantages.There is a massive contradiction between data representation and rendering efficiency.This paper introduces parallel technology into the field of mine visualization,and studies the parallel volume rendering algorithm based on the volume mineralization model.The research in this article mainly includes the following aspects:Firstly,this paper collects geological data such as exploration drilling data and production drilling data,and carries out coordinate transformation,discretization and regularization processing on the data;Secondly,according to the theory of mine compound field,the characteristics of the volume mineralization model are analyzed,and a parallel volume mineralization model is constructed;Thirdly,based on the analysis and design of the ray casting algorithm,the parallel ray casting algorithm is designed,and the parallel rendering of the volume mineralization model is realized;Finally,based on the data of a mine,the CPU + GPU architecture is used to realize the parallel rendering of the volume mineralization model on the GPU.The experimental results show that the rendering effect and rendering speed have been significantly improved.
