极坐标这种方式虽然有所限制但却十分简单。

Below you will find the same functions in the cartesian graph and in a polar coordinates shader example (between *lines 21 and 25*). Uncomment the functions one-by-one, paying attention the relationship between one coordinate system and the other.

下面你会看到在同样在笛卡尔坐标下图形在极坐标下的着色器案例(在 *lines 21 和 25*之间)。对这些函数一个个取消注释,看看两坐标系之间的联系。

<div class="simpleFunction" data="y = cos(x*3.);

//y = abs(cos(x*3.));
