用平行线绘制瓶子

通过这种绘画方式，仅用平行线就能营造出三维视觉效果。六年级学生使用记号笔绘制了这些瓶子，他们选取三至四种颜色的序列，并反复运用该序列来完成整个瓶子的绘制。背景也采用相同技法绘制，但使用了不同的颜色序列。

我们首先在绘图纸上用铅笔画出五至六个瓶子；瓶子需画得较大，以占据画纸约一半的空间。瓶子顶部的瓶颈须略向外弯曲，从而营造出体积感。我们在整个瓶子上重复绘制三至四种颜色的序列，线条须紧密、平行且保持相同的弧度。背景则从画纸中央起始，以微小的弧线为起点，绘制弯曲的平行线。我们另选一组颜色序列，以增强瓶子与背景之间的对比度。如想查看类似作品，请点击此处欣赏三维蛇形图案，以及此处欣赏三维树形图案。

Drawing bottles with parallel lines

With this drawing you can create a three-dimensional visual effect just with parallel lines. Students of Grade 6th have drawn these bottles with felt-tip pens, choosing a sequence of three or four colours and repeating it to complete the bottle. The background has been drew with the same technique but with different colours.

We start drawing five or six bottles with a pencil on a drawing paper; the bottles have to be quite large in order to fill half of the space on the drawing sheet. The neck of the bottle at he top must be slightly curved outwards, to give the illusion of volume. We draw a sequence of three or four colors repeating them on the whole bottle. The lines must be close and parallel, with the same curve. For the background we draw curved, parallel lines starting with a little arc from the middle of the drawing sheet. We choose a different sequence of colors to create more contrast between the bottles and the background.
