The Application And Expression Of Geometric Figures In The Design Of Contemporary Public Welfare Posters

As a carrier of information dissemination,the public welfare poster has the function of disseminating information beyond language and ethnicity,and has gradually become an internationalized communication method.The geometry formed by the combination of points,lines,and faces can express and interpret the content more intuitively,and the viewer can obtain related information through visual visual images.Therefore,the use of geometric representation techniques makes public service posters more concise,intuitive,eye-catching,and memorable.This article explains the characteristics and symbolic meaning of geometric figures from theory and practice application.Through the analysis of the use of geometric figures in the design of public welfare posters at home and abroad,the basic application methods and laws of geometric figures in the design of public welfare posters are grasped;The graphic is used in the design of public placards to integrate with the traditional modeling meanings.Through repeated practice,it seeks out its new structure combination and gives the visual image a new meaning.In practice,the superposition and reorganization of points,lines,surfaces,and basic geometric shapes such as circles,squares,and triangles are used to enhance the visual expression.The process is not a simple listing and consolidation of geometric figures.It is based on the addition or subtraction of the geometric shapes to extract required basic elements of the shapes,and use it for the reorganization and reconstruction of the image,The purpose is to use simplified and generalized geometric figures to enhance the expression and visual appeal of the work.The research in this paper focuses on the visual perception brought by the use of geometrical figures.In conjunction with the thematic expressions of public welfare posters,this symbolism hidden behind geometric forms can be perceived and disseminated,facilitating the visual information change and communication of people in rapid social life.The practice part of this article mainly focuses on the design practice of using geometric figures for selected public service posters,and explores the issues involved.
