Abstract

The invention relates to the technical field of three-dimensional visualization, and discloses a method for three-dimensional underground space visualization, and the method comprises the steps: obtaining a terrain boundary sampling point and a building boundary sampling point of an underground space in a three-dimensional scene; obtaining an outer boundary line of the section of the underground space according to the terrain boundary sampling points, and obtaining a building boundary line according to the building boundary sampling points of the underground space; acquiring the section of the underground space according to the outer boundary line and the building boundary line at the section; and loading and displaying the section of the underground space through a preset three-dimensional engine. According to the method, the effect of carrying out three-dimensional visual display on the underground space is improved. The invention further discloses a device for three-dimensional underground space visualization, a computer and a storage medium.

Description

technical field [0001] The present application relates to the technical field of three-dimensional visualization, for example, to a method and device for three-dimensional underground space visualization, a computer, and a storage medium. Background technique [0002] With the continuous progress and development of modern urban construction, more and more attention has been paid to the utilization and development of urban underground space. However, because the subjects involved in urban underground space are often hidden, the display of buildings in underground space is often more difficult than that of buildings on the ground. more difficult. At present, the underground space of the city is mainly displayed and analyzed by hiding or translucent the ground. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: [0004] In the prior art, the underground space is displaye...
