With hidden - line elimination , ambiguity of graphic can be eliminated , which is important in getting a realistic scene 消隱可以消除圖形的二義性,它是得到場景真實感的一個很重要的方面。
Furthermore , unlike other algorithm , it is free of the definition of weight and estimation of parameters in order to get a realistic image , it is necessary to do processing works , such as transform of plot , hidden - line elimination , illumination , texture mapping , to the 3d models constructed through interpolation 通過插值建立它的三維模型后,要得到真實感圖像,還必須對三維模型施以繪圖變換、消隱、光照、紋理映射等處理。
