摘要 介绍了E CAD,一个模拟钢笔画绘制生成建筑场景以及设计图纸的CAD系统,以及系统中实现的一种参数化过程纹理描述语言。从系统的角度具体阐释了为了支持NPR绘制,系统在内核的选择、开发、实体造型、系统框架、渲染体系结构、控制流程和显示模块方面相应的设计和实现。 We describe ECAD,a system that is designed to produce penandink illustration for presentation of architectural drawings.In this paper,we present the solid model,system architecture,NPR pipeline,display module and techniques supporting the NPR technology.Examples illustrated in penandink,demonstrating the capabilities of presenting 3D scene are also given.
