【摘要】 以建筑物"台阶"为例,介绍了应用AutoCAD2000的AEM模块,准确地构造出三维实体的方法,通过设置光源,模拟常用光线使建筑三维实体产生阴影。并利用多视窗功能,采用渲染的方法自动生成阴影的投影,将生成的阴影图应用于阴影透视CAI课件中,取得了良好的教学效果。更多还原

【Abstract】 Taking a flight of stairs as an example, the way to construct 3D solid exactly by using AEM Model of Auto CAD 2000 is showed. 3D solid is caused to form shadows by setting light sources and simulating commonly used light. In addition, by making use of multiviewports, the author uses "Render" to automatically form projections of the shadows and applies the drawings of the shadows to Shadow Perspective CAI courseware. Good teaching effect has been achieved.更多还原
