CUDA 编译器，链接 OpenVDB 在 Blender 中查看导出的结果 边界条件 边界条件：初始化 边界条件：添加判断边界的版本 边界条件：仅在第一层额外判断边界条件 进一步改进 VDB 导出：支持导出多个网格，并指定名称 进一步改进 VDB 导出： P-IMPL 模式 进一步改进 VDB 导出： F-IMPL 模式 Blender 渲染结果 改进 改进边界条件：外部边界流出而不是反弹，内部边界可以流出速度 改进边界条件：外部边界流出而不是反弹，内部边界可以流出速度 Blender 中调整一下材质 Blender 中调整一下材质 改进对流：让烟雾随时间逐渐褪色 改进对流：让烟雾随时间逐渐褪色 改进褪色：不是褪色 density ，而是褪色 temperature 改进褪色：不是褪色 density ，而是褪色 temperature 改进褪色：不是单纯地乘以 decayRate ，还和周围环境温度求平均值

函数，从而保证 pool 解 构时会自动等待全部线程执行完毕。 小彭老师快乐吐槽时间 • 多线程、异步、无阻塞、并发，能提升程序响应速度，对现实世界中的软件工程至关重要 。 • 反面教材： blender 在运行物理解算的时候，界面会卡住，算完一帧后窗口才能刷新一遍 ，导致解算过程中基本别想做事，这一定程度上归功于 opengl 原始的单线程设计。 • 正面教材： zeno 可以在解算过程中

Everything Runs on UI Thread* • Plugins created with native code • React Support • API Access via Native Modules • UI Thread vs JS Thread • Angular/Vue/Vanilla vs React • Progress vs Facebook • Apache 2.0 vs native APIs still available at JavaScript layer for platform-specific scenarios o NativeScript modules follow Node module conventions (CommonJS) Example: NativeScript file module BUT HOW DO I TURN Pages/Views o XML markup structure o Elements (e.g. , ) are NativeScript modules NativeScript Modules for UIs UI Widgets o Button o Label o TextField o TextView o SearchBar o Switch o Slider
