Since pixel - level contrapose pixel coordinate , trigonometric function must be used to translate polar coordinates to pixel coordinate when the curve is described by polar coordinate . so research is very little on algorithms for generating this sort of curve by now 由于逐点是针对象素坐标系而言,而对极坐标系下描述的曲线,在转换到象素坐标系时要用到三角函数运算,因此目前很少提到对极坐标曲线生成算法的研究。
