摘要
利用计算机软硬件技术,在不使用附加板卡的普通微机上开发实用的公路立体线形三维动画显示系统。采用能模拟公路的路面、边坡、挡墙、桥梁、隧道和交通工程设施等的可见部分表面模型,通过透视变换、消隐处理、加上颜色纹理进行着色,生成一幅幅具有较强真实感的公路全景透视图。通过色彩压缩和数据压缩,生成动画序列,将动画序列调入内存,进行解压缩处理,形成电影式的动画片。
: The main motive of the paper is to develop a 3D animation performance system in highway alignment realization simulation, on PC with no additional panel or card installed. We use perspective shifting, hiding, coloring and mapping method to render the surface model of engineering structure, such as pavement, slope, retaining- wall, bridge, tunnel, and other traffic engineering facilities. A series of full- view perspective of highway alignment are revealed. By color and data compressing, animation series are generated, where after the series are transferred to memory for decompressing. As the result, movie- like animation is come into being.
