Embodiment Construction
[0041] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0042] In the 3D scene of the webgis system of the smart city business, the 3D building is required as the basic element of the visual scene, and the amount of building data constructed by modeling is usually too large. When the application is stable, too long data transmission time will seriously affect the application experience. In the context of the increasing demand for high-performance rendering of 3D buildings in the 3D visualization of the webgis system, a solution that can solve the problem of compressing building data and high-performance rendering on the web is needed for automati...

The invention discloses an urban three-dimensional building visualization construction method, terminal equipment and a storage medium. The method comprises the following steps: acquiring original three-dimensional building data, and compressing the original three-dimensional building data to obtain compressed three-dimensional building data; decoding the compressed three-dimensional building data, and constructing vertex information of a building geometric object; and building an urban three-dimensional building model according to the vertex information, and carrying out visualization processing on the urban three-dimensional building model. By means of the technical scheme, the visual display of urban three-dimensional buildings can be achieved, and the stereoscopic impression of the building effect is improved.
Description
technical field [0001] The present invention relates to the technical field of three-dimensional display, and in particular to a method for constructing a visualized urban three-dimensional building, a terminal device and a storage medium. Background technique [0002] In the 3D scene of the webgis system of the smart city business, the 3D building is required as the basic element of the visual scene, and the amount of building data constructed by modeling is usually too large. When the application is stable, too long data transmission time will seriously affect the application experience. In the context of the increasing demand for high-performance rendering of 3D buildings in the 3D visualization of the webgis system, a solution that can solve the problem of compressing building data and high-performance rendering on the web is needed for automatic construction and rendering of 3D buildings. [0003] Therefore, the prior art still needs to be improved and improved. Cont...
