In addition , java3d can only accomplish the regular geometry sculpting and ca n ' t accomplish the irregular geometry sculpting . to solve this flaw , a new way of sculpting the gyre - solid and changing - section - brace by approaching the solid with small slice is put forward . at the same time , rendering and third dimension disposing are settled in this paper 另外,在系統(tǒng)開發(fā)過程中,針對java3d三維造型功能類中僅包含標準幾何形體的問題,這里用四邊形面片逼近曲面的方法解決了回轉(zhuǎn)體和變截面曲柄的三維建模,以及這種建模方式下的渲染和真實感處理問題。
