White mold building stroking method and device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a white mold building stroking method and device, computer equipment and a storage medium. The method comprises the following steps: analyzing GeoJson data; setting a two-dimensional data array; geometric white mold building height information is extracted; traversing the two-dimensional data array; creating a vertex array and an inner hole array, and determining a data arrangement direction of a current ring to obtain a first direction; circularly traversing the residual ring array data in the two-dimensional data array by using whle; judging whether the data arrangement direction of the traversed current ring is consistent with the first direction or not; if yes, determining a vertex index; creating a position data array; constructing top patch index data; constructing stroke index data; constructing side index data; judging whether the two-dimensional data array is traversed or not; and if yes, constructing a geometric white mold stroking building. By implementing the method provided by the embodiment of the invention, no art design intervention is needed, the personnel cost demand is reduced, the memory consumption in the model drawing process is reduced, and the rendering performance is improved.

Description

technical field [0001] The present invention relates to a method for processing GIS geometric white mold strokes, and more specifically to a white mold architectural stroke method, device, computer equipment and storage medium. Background technique [0002] The number of GIS (Geographic Information System) buildings is huge, and the white model stroke effect of geometric buildings is manually completed. The process is cumbersome and prone to errors and omissions. Generally, the visual effect of geometric white model building strokes after post-processing is also difficult to match with real ones. Compared with the white model stroke of a single geometric building, or after the geometric building is stretched and created, the wireframe of the white model building is used to add a stroke effect, and the rendering performance is poor and the memory consumption is large. [0003] In the actual development process, the stroked geometric white model building is an important scene ...

Problems solved by technology

Stroke luminous translucent top and side architectural effects, but it is difficult for general program developers to achieve this effect, most of them can only be manually set by artists to make geometric stroke architectural white molds in designated areas, which is difficult to target at the whole country or the world Volumetric data are processed
