Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] refer to figure 1 A preferred embodiment of a method for realizing a 3D cloud layer simulation of the present invention comprises the following steps:

[0026] Step S1. Create a 3D sky dynamic background that changes over time: the sky background effect that gradually changes over time can be achieved through UV coordinate transformation animation. The method is to use only one picture, and move from left to right in this picture It reflects the gradient effect of the sky color within a day, and switches the UV coordinate range of the sky sphere according to the time, so that it can appear ...

Abstract

The invention provides a method for realizing 3D cloud layer simulation, which comprises the following steps of: A. making a 3D sky dynamic background varying with time; B. drawing a plurality of design sketches for a cloud sheet to form cloud form images; C. generating a single cloudlet by arranging a plurality of cloud sheets in a cubic space, carrying out the random sampling from the cloud form images by using random setting of UV coordinates according to different heights of cloud layers; D. setting the position attribution of each cloudlet after generating a plurality of the single cloudlets so as to generate a cloud layer; E. regulating the display of the 3D dynamic sky background in real time and setting real-time colors of the cloud layers according to current time; F. adding the dynamic effect for the cloud layers. By adopting the method, efficient and complicated cloud layer effects can be made by using several 2D design sketches of cirrus clouds or cumulus clouds and regulating the quantity of the cloud sheets and clouds, then more real and natural cloud layers can be simulated by regulation of a light source and addition of the dynamic effects.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to a method for realizing 3D cloud layer simulation. Background technique [0002] In the existing simulated cloud layer display technologies, either 2D animation is used, which cannot play a better role in 3D space, or the use of PC platform requires a lot of calculations and complex image processing, which is not suitable for those with poor processing capabilities. mobile platform and smart TV platform. At present, there is no method for displaying 3D cloud layers and dynamic effects on platforms with low computing power (such as portable electronic devices such as mobile phones). Contents of the invention [0003] The purpose of the present invention is to provide a method for realizing 3D cloud layer simulation, which can conveniently and quickly display 3D cloud layer on a platform with low computing power, and provide the dynamic effect of cloud layer. [0004] Technic...
