ParametricGeometry 允许你用数学公式来定义形状。这里的 klein 函数生成了一个著名的数学模型——克莱因瓶。它是一个没有“内”和“外”之分的奇怪瓶子。对于初学者，你只需要知道：只要你能写出 x, y, z 的方程，Three.js 就能帮你画出模型。

How often does the "slow path" actually trigger? With 32 TLB entries covering 128 KB, Intel claimed a 98% hit rate for typical workloads of the era. That sounds impressive, but a 2% miss rate means a page walk every 50 memory accesses -- still quite frequent. So the 386 overlaps page walks with normal instruction execution wherever possible. A dedicated hardware state machine performs each walk:
HTMLMediaElement.prototype.play = function () {
