Abstract

In order to solve the problems of real-time, robustness and accuracy of the current profile generation, in this paper it proposes to solve the calculation bottleneck of the cutting problem from the perspective of image space by using the double stencil buffer technology. With the help of Render To Texture camera technology and high-resolution technology, the high-precision output of the profile under arbitrary route cutting is realized. Finally, the profile is vectorized to obtain the vector geological profile with attributes. Experiments show that the real-time generation technology of vector geological profile based on three-dimensional geological model is feasible. Compared with the traditional cutting, it is proved that our method has greatly improved the cutting efficiency, realizing the real-time generation of the profile and the exquisite and beautiful output of the vector profile. It provides a new idea for real-time profile generation based on three-dimensional geological model under the background of geological industry entering the era of three-dimensionalization, and achieves a multiplier effect.
