在一些讨论几何画板使用方法的群里,很多网友询问如何给图形加上阴影,这里把平时积累的一些制作方法写出来,与同行们分享.给图形加上阴影的方法,总起来说主要有构造内部和构造轨迹两种方法.构造内部和构造轨迹的命令都在几何画板的【构造】菜单里.根据选中对象的不同,【内部】命令会相应地显示为【n边形内部】、【圆内部】、【弧内部】(又分为【扇形内部】和【弓形内部】),执行这些命令可直接构造出阴影:【轨迹】命令可构造线
In some groups discussing how to use geometry palettes, many netizens ask how to add shadows to their shapes, and here they write out some production methods they usually accumulate and share them with their counterparts. Construct the interior and the construction of the two methods of the track.Construct the internal and construction of the trajectory of the command are in the geometry board 【Structure】 menu.According to the selected object, the 【Internal】 command will be displayed corresponding to the 【n inside the polygon】 【 Circle inside】, 【arc inside】 (divided into “fan inside” and “bow inside”), execute these commands to construct the shadow directly: 【trace】 command can construct the line
