Abstract
at presentthere are a lot of problems with model simplification al gorithms when rendering3dgeometric and terrain models testing the relationshi p between quality and the dis pla y effect.in order to maintain visual characteristics of the modela reasonable implementation model for simplifica tion is put forward.this model simplification al gorithm solves the reflection of the lod simplifiedmodel by introducing a vertex curvature characteristic factorlimitin g narrow trian gle formation andsi gning trian gles whose color changed quite differentl y.experimental results show thatthe al gorithmis efficient when guaranteeing the visual features of the simplified modelandcan be used to the terrainrendering of 3dscene.
