Abstract

The invention relates to a processing method and device for simulating an explosion flame effect in a GIS system based on graphics. The method comprises the steps that entities and expressions are abstracted into geometries and materials in advance; the explosion special effect is compiled for materials, and codes of a vertex shader and a fragment shader are directly compiled by utilizing self-defined coloring material materials to define the materials; taking an initial vertex of a three-dimensional sphere geometry as basic data of a flame explosion special effect; obtaining normal vectors ofvertexes of the three-dimensional spherical surface needing to simulate the explosion flame through a vertex shader; obtaining a current time and a position coordinate position; calculating the latest position of the current vertex through a Berlin noise algorithm; and loading the flame special effect chartlet by using a fragment shader to finish overall special effect rendering. According to theinvention, the special effect of flame explosion can be conveniently realized, the explosion flame effect can be simulated in a GIS system, the user operation and use are convenient, the realizationis simple, and the reliability is high.

Description

technical field [0001] This application relates to the technical field of network geographic information systems, in particular to a method and device, computer equipment, and a readable storage medium for processing simulated explosion flame effects in a GIS system based on graphics. Background technique [0002] In the field of webgis (web geographic information system), it is often necessary to visualize and restore some events or effects. For example, to restore the flame, combustion and explosion effects of fire accidents, these special effects are often difficult to achieve, or the implementation efficiency is so poor that they cannot be integrated and used. [0003] The existing webgis system itself is more inclined to professional geographic attribute functions, and basically does not provide some vivid special effects integration, but in practice, some requirements will be encountered when using the webgis system for business development, such as in disaster analysi...
