沙发又被我抢了。{:4_170:} 本帖基于 three.js 的 webGPU API,仅为测试。
WebGPU 相对于 WebGL 更为强大,但是目前它的兼容性还做得不好,three.js 对此采用了一个回退机制,所以在非 https 协议的网站中,控制台会有一个警告级别的提示。 鼠标跟随能互动的超级好玩。。。
这个星星是彩色的,鼠标移动的方向跟星星运动方向不同

警告是无关紧要的。错误才是致命的:运行不了。

开始学代码时整过不能运行的,这个见过
论坛应该能兼容多数效果吧。。不然它会被用的人淘汰的 马黑黑 发表于 2025-5-3 17:55

你发的贴子啊,有补充说明是正常的。你总 不能把东西放在沙发上。。
所以回复的第一个人坐的就是沙发。{:4_173:} 马黑黑 发表于 2025-5-3 17:56

看到引用了两个JS,还有这么大一群代码,每个代码都是一颗星星的节奏。{:4_173:} 马黑黑 发表于 2025-5-3 17:57

各种颜色随机出现,这个色更好看些。。 花飞飞 发表于 2025-5-3 18:06
看到引用了两个JS,还有这么大一群代码,每个代码都是一颗星星的节奏。
第一个JS是引路用的,用来构造资源对象。three.js 需要引入太多资源,这些资源目前来源于那个 esm.sh 中转站,目前是比较好用的 花飞飞 发表于 2025-5-3 18:06

这个不是论坛的问题,是网站的协议,http 和 https ,前者现在被认为是不安全的,用个 WebGPU 接口也会警告有危险。
