摘　　要：CGA形状语法是一种新的模拟计算机图形的语言,能够程序化地产生高视觉效果和详细几何信息的建筑。它能够以很低的成本广泛地用于电脑游戏和电影等的建筑物建模。清晰的等级规则可以让用户方便地指定建筑物之间的层次关系。CGA形状语法表明它能够有效地产生大规模的具有非常详细程度的城市,能够解决以前大规模模型建立过程中在任意方向和形状方面的详细程度问题。CGA shape grammar is a new simulation computer graphics language which is able to produce a high visual impact of the globalization process and detailed geometric information architecture. It can be widely used at very low cost for the modeling of build- ings in computer games and movies. Context sensitive shape rules allow the user to specify interactions between the entities of the hier- archical shape descriptions. CGA language suggests that it can effectively produce large - scale and a very detailed level of cities, which is able to solve large - scale model building process before the arbitrary direction and shape of the level of details.
