SVG stroke-dasharray偏移不一致

我认为你的设置有两个轻微的错误.

第一个是点的间距是stroke-dash数组的2个参数的总和.由于第一个参数始终为0.001,因此第二个参数应为公式减去0.001的结果.

第二个是你在圆圈周围放置36个点.从点到点的角度给出10度.所以,你的动画应该特定10deg,20deg,30deg为系列,而不是15deg 30deg 45deg ...这会在每个周期结束时产生5度的跳跃.

我认为我或多或少都在工作

小提琴

初始轮换也存在问题; 我希望现在这就是你想要的.

而且,由于svg的小尺寸,还有一些回合; 将它设置为600平方的效果要好得多.

我还在10度处添加了一条线来检查点的正确对齐.

并且还优化了一点风格

好吧,经过大量时间花在这个问题上,我几乎可以肯定在某种舍入/精度中存在某种错误.

我完全改变了这个想法以避免这个问题.目标是在结束动画之前使圆圈成为圆圈,以便动画的开头和结尾始终保持同步.

由于这会产生巨大的关键帧样式,我想重用它; 为了达到这个目的,我以嵌套的方式对圆圈进行了分组; 并将动画应用于每个组:

和新的演示 (对不起,只有webkit)

这是我尝试调查错误.我改变了系统,而不是动画,我有2组圆圈,一组颜色,另一组黑色,旋转10度.色圈不应该显示; 偏移量是衡量误差的一个指标.(可能需要滚动才能看到圆圈

抵消演示
