用計(jì)算機(jī)程序制作三維立體畫(huà)

該程序寄生在Windows 3.1中的Pbrush軟件上。借助于它來(lái)構(gòu)筑立體形體(即立體形體水平剖面高低坐標(biāo)數(shù)據(jù)文件圖8),設(shè)計(jì)原始圖案(圖9)。程序運(yùn)行后,逐行輸入并處理以上兩個(gè)文件中的圖形,然后輸出立體畫(huà)結(jié)果文件(圖10)。最后,用Pbrush來(lái)觀賞立體畫(huà)result.bmp。當(dāng)然,要設(shè)計(jì)出令人賞心悅目的立體畫(huà),必須在立體形體和圖案素材的選擇和搭配上做到天衣無(wú)縫,獨(dú)具匠心。
