巧用Illustrator渐变网格绘制苹果

<font face="Verdana">的渐变</font>网格工具能产生更为自由和丰富的渐变色彩填充,其色彩过渡的表现非常出色,甚至成为许多设计师进行艺术创作的主要工具。今天我们就来用这个神奇的工具绘制一个逼真的大苹果。<br/><br/>  网格工具(Mesh Tool) <img height="21"

方法二:有时网格线的分布要求会与色块形状产生冲突,不易设置,此时可先设网格线分布,然后用 Ctrl+7 裁切到边缘轮廓以内即可,如下图。 </p><table bordercolor="#999999" height="95" cellspacing="0" width="613" border="0"><tbody><tr><td class="style6"
