# WebGL 插件的限制

### 大小限制

iOS 浏览器对 WebGL 构建的大小施加严格限制。这些限制主要是由于：

* 内存限制：iOS 设备可用于 Web 应用程序的可用内存有限，这会影响运行大型 WebGL 构建的性能和可行性。
* 浏览器存储配额：Safari 和其他 iOS 浏览器会限制可在本地存储的数据量。这包括缓存和 Indexed DB，它们通常用于存储 WebGL 构建的资源。

### 主要限制

* 可下载资源的最大大小：iOS 浏览器可能会限制单个可下载资源的大小。大型资源可能无法加载，导致应用程序崩溃。
* 总构建大小：为保证流畅性能，所有资源合计的总大小最好控制在 50-100 MB 以下。超过此限制可能会导致崩溃或极其缓慢的加载时间。
* 内存使用：与桌面环境相比，iOS 设备通常可用的 RAM 更少。WebGL 构建的高内存占用可能会导致浏览器频繁崩溃。

### 浏览器兼容性

* Safari：iOS 上的默认浏览器 Safari 通常是 WebGL 构建的最佳选择，但与其他桌面浏览器相比，它仍然有明显的限制。
