它是怎么做的
- 第 1 步鼠标轨迹生成一串带速度的粒子。
- 第 2 步粒子受噪声场与弹性约束影响缓慢漂移。
- 第 3 步相邻粒子之间以低透明度描线，叠加混合产生发光感。
- 第 4 步按旋转/镜像对称把同一笔画复制多份。
复刻配方
一段技术配方，可以直接交给 AI 编程助手，也可以自己照着写。想指定技术栈、位置和性能预算，就把它加入实现方案。
On drag, emit points into a list with velocity from pointer movement. Each frame advect points through a slowly evolving 2D noise field and dampen velocity, then stroke a polyline through them with very low alpha and 'lighter' composite mode so overlaps glow. Draw the same polyline N times rotated around the canvas center (and optionally mirrored) for symmetry. Never clear the canvas while drawing, so strokes accumulate; add a soft ambient pad with WebAudio whose filter cutoff follows stroke speed.
