i关于本工具
用途说明
在线抽奖面向年会、团建、直播互动等职场与活动场景，支持自定义抽奖标题、抽取人数与姓名名单。开奖舞台基于 Three.js 构建粒子光环；点击开始滚动、再点击停止开奖，支持全屏展示与人名翻页动效。名单去重、本地随机抽取、中奖结果可复制；配置保存在本机浏览器，纯前端运行，不上传服务器。
使用步骤
- 填写抽奖标题，设置本轮抽取人数。
- 在名单框中输入姓名（每行一个，或用逗号分隔），可点击打乱名单并应用配置。
- 需要投屏时点击舞台右上角「全屏」。
- 点击舞台或「开始抽奖」开始滚动人名；再点击一次「停止开奖」锁定当前显示姓名。
- 若本轮需抽多人，停止后再次点击继续；在中奖名单中复制结果，或「重置结果」重来。
常见问题
Three.js 会拖慢其他工具吗？
不会。3D 引擎仅在打开本工具时按需加载，其他页面不会下载 three.min.js。
停止时以谁为准？
停止瞬间舞台上显示的姓名即为中奖者（来自剩余名单）。
可以一次抽多人吗？
可以。设置抽取人数后，每人需点击开始→停止；不会重复抽中同一人。
结果公平吗？
采用浏览器本地伪随机；适合娱乐互动，不构成公证或区块链抽奖。
数据会上传吗？
不会。标题、名单与结果仅保存在本机 localStorage。
上文已说明该工具是本地处理还是会调用第三方接口，请按场景选用。
What it is for
Lucky Draw is for workplace parties, team events, and livestream giveaways. Configure a title, winner count, and name list. The stage uses Three.js particle rings; click to start rolling, click again to stop. Fullscreen and name-flip transitions included. Names are de-duplicated, winners are drawn locally, and results can be copied. Settings stay in your browser — fully local.
How to use
- Enter a draw title and set how many winners to pick this round.
- Paste names (one per line or comma-separated); shuffle and Apply as needed.
- Use Fullscreen on the stage for presentations.
- Click the stage or Start to roll names; click again to Stop and lock the shown name.
- For multiple winners, click again to continue; copy results or Reset to start over.
FAQ
Will Three.js slow other tools?
No. The engine loads only when you open this tool.
Who wins when I stop?
The name shown on stage at the moment you stop becomes the winner (from the remaining pool).
Can I draw multiple winners?
Yes. Set the winner count; each person needs Start → Stop. No duplicates.
Is it cryptographically fair?
It uses local pseudo-randomness for entertainment — not a notarized or on-chain lottery.
Is data uploaded?
No. Title, names, and results stay in localStorage.
Processing notes above describe whether work stays in your browser or calls third-party APIs.
