FAQ

粒子背景对性能有影响吗?

粒子系统使用Canvas 2D渲染,现代浏览器对此有良好的性能支持。你可以通过调整粒子数量和速度来控制性能消耗。建议保持粒子数量在100-200之间以平衡视觉效果和性能。移动端建议使用更少的粒子。

可以商用吗?

可以。本工具生成的代码完全免费,可用于个人和商业项目,无需署名。生成的代码不包含任何版权限制。

粒子之间的连接线效果是怎么实现的?

连接线效果通过计算每两个粒子之间的距离来实现。如果两个粒子之间的距离小于设定的阈值(如150px),就在它们之间绘制一条半透明线条。距离越近,线条越明显。这种效果可以增强粒子系统的视觉连贯性。

可以添加鼠标交互吗?

可以。工具提供鼠标交互选项,开启后粒子会受到鼠标位置的影响,产生吸引或排斥效果,或者鼠标附近的粒子连接线会更亮。交互效果增强了页面的互动感和科技感。
