KISS

Subject:    Focus on Problems vs. Focus on Solutions-Don’t miss reading


1.One of the most memorable case studies on Japanese management was the case of the empty soap box, which happened in one of Japan’s biggest cosmetics companies. The company received a complaint that a consumer had bought a soap box that was empty. Immediately the authorities isolated the problem to the assembly line, which transported all the packaged soap to the delivery department. For some reason, one soap box went through the assembly line empty. Management asked its engineers to solve the problem.
Post-haste, the engineers worked hard to devise an X-ray machine with high-resolution monitors manned by two people to watch all the soap boxes that passed through the line to make sure they were not empty. No doubt, they worked hard and they worked fast but they spent whoopee amount to do so.
But when a rank-and-file employee in a small company was posed with the same problem, did not get into complications of X-rays, etc but instead came out with another solution. He bought a strong industrial electric fan and pointed it at the assembly line. He switched the fan on, and as each soap box passed the fan, it simply blew the empty boxes out of the line.
Moral of the story: KISS (Keep It Simple,Stupid) i.e. always look for simple solutions. Devise the simplest possible solution that solves the problem.


2.When NASA began the launch of astronauts into space, they found out that the pens wouldn’t work at zero gravity (Ink won’t flow down to the writing surface).
In order to solve this problem, it took them one decade and $12 million. They developed a pen that worked at zero gravity, upside down, underwater, in practically any surface including crystal and in a temperature range from below freezing to over 300 degrees C.
And what did Russians do………………………..??

以上短文的大概意思如下:
  日本最大的化妆品公司收到客户抱怨买来的肥皂盒里面是空的,于是他们为了预防生产线再次发生这样的事情,工程师便很"努力辛苦"的发明了一台X-光监视器去透视每一台出货的肥皂盒。
  而同样的问题发生在另一家小公司,他们的解决方法是买一台强力工业用电扇去吹每个肥皂盒,被吹走的便是没放肥皂的空盒。

 

### KISS3D生成器的使用与文档 KISS3D 是一种用于三维图形渲染的 Rust 库,它提供了简单易用的功能来创建和操作 3D 场景。以下是关于如何使用 KISS3D 的一些基本指导以及其功能概述。 #### 安装与配置 为了在项目中使用 KISS3D,需将其作为依赖项添加到 `Cargo.toml` 文件中: ```toml [dependencies] kiss3d = "0.27" nalgebra = "0.28" # kiss3d 使用 nalgebra 进行线性代数运算 ``` 完成上述设置后,可以通过运行 `cargo build` 或者 `cargo run` 来构建并测试程序[^1]。 #### 基本场景初始化 以下是一个简单的例子,展示如何通过 KISS3D 创建一个窗口并在其中显示立方体对象: ```rust extern crate kiss3d; extern crate nalgebra as na; use kiss3d::window::Window; use kiss3d::scene::SceneNode; use na::{Point3, Vector3}; fn main() { let mut window = Window::new("KISS3D Example"); // 添加一个立方体节点至场景 let mut cube: SceneNode = window.add_cube(1.0, 1.0); // 设置初始位置 cube.set_position(Point3::new(-0.5, -0.5, 0.0)); while !window.should_close() { // 更新每一帧的内容 window.render(); // 修改物体的位置或其他属性 cube.prepend_to_translation(&Vector3::new(0.01f32, 0.0, 0.0)); } } ``` 此代码片段展示了如何启动一个新窗口,并向该窗口添加一个立方体模型。还演示了如何更新每帧中的内容以实现动态效果[^2]。 #### 高级特性支持 除了基础的对象绘制外,KISS3D 支持多种高级特性,比如光照、材质贴图、相机控制等。这些都可以进一步增强所开发应用的表现力。例如,可以自定义光源方向及其强度;或者加载外部纹理文件应用于特定几何形状上。 对于更复杂的交互需求,还可以利用键盘输入事件处理机制调整视图角度或移动虚拟摄像机视角[^3]。 ---
