笔记 Notes
这里记录形状、运动和声音怎样从数学关系变成可以运行的代码。图片和代码都来自项目本身。 These notes follow form, motion, and sound from mathematical relationships into working code. The images and excerpts come from the projects themselves.

从公式到一首歌：用代码和数学合成音乐From Formula to Song: Making Music with Code and Mathematics
From Formula to Song: Making Music with Code and Mathematics
声音在文件里只是一列数字。音高来自周期，音色来自谐波，起伏来自时间。把这些关系分层写进代码，一首歌就可以从零生成。 In a file, sound is only a column of numbers. Pitch comes from periodicity, timbre from harmonics, and phrasing from time. Layer those relationships in code and a complete piece can be generated from nothing.

海上列车：用 Three.js 写一片安静的海Sea Train: Writing a Quiet Ocean in Three.js
Sea Train: Writing a Quiet Ocean in Three.js
这个场景只有几样东西：水、列车、电线和夕阳。画面能不能成立，取决于镜头、反射和时间之间的关系。 This scene contains only water, a train, wires, and a setting sun. Whether the image holds together depends on the relationships between lens, reflection, and time.

用 Three.js 造一辆自行车：先算几何，再画模型Building a Bicycle in Three.js: Geometry Before Meshes
Building a Bicycle in Three.js: Geometry Before Meshes
自行车看上去是车架、轮组和传动，底下其实是一组互相约束的点。先把这些关系算清楚，再让 Three.js 负责画出来。 A bicycle looks like a frame, wheels, and a drivetrain. Underneath, it is a set of points constrained by one another. Solve those relationships first, then let Three.js draw the result.
