《始末》系列是关于 Dandelion 1.0 版本的个人回忆，而这是系列里关于实现过程和细节的最后一篇。完成前面的诸多工作之后，利用场景、物体数据和渲染机制，再配合独立性很强的求解器，物体就可以运动起来了。

原计划一口气写完《始末》这个系列，却在去年年初中断。写下这篇文章的时候已经是 2025 年，实在始料不及。这篇文章着重于 Dandelion “建模模式”背后的交互实现与数据同步机制，而不是几何算法，因为我认为前者是回忆录中更值得回顾的部分。

忙得有些生厌，遂出门闲逛。乍一想起来西安四年半了还未去过青龙寺，转念又想，没去过的地方且多了去，想到哪里去哪里逛逛就是了。 看过才知道，青龙寺实名青龙寺遗址，而所谓遗址当指的是被发掘的若干地基及文物，并无地上建筑存留。今之青龙寺遗址博物馆及寺院，多半是钢筋混凝土结构——样式不错，不过在西安也不算出奇。 此时立夏已一周，牡丹之类俱已开败，园子里已找不到多少花。然而初夏之际，草木茂盛最为可观，加上游人

GAMES 101 的实验中包含了经典的光栅化渲染、Whitted-Style Ray-Tracing 和路径追踪，加上闫老师高质量的课程内容，已经把局部光照渲染和全局光照渲染这两种视角展示得很不错了。但我从开始做 101 的实验时就产生了一个遗憾——为什么不能用我自己编写的工具来渲染任何我想要渲染的模型呢？而这正是 Dandelion 想要弥补的地方。

OpenGL 标准描述了一种 C/S 架构的 GPU 编程模式：CPU 上执行的程序是 Client ，通过调用 API 可以查询或更改全局状态，也可以请求渲染；GPU 是 Server ，响应查、改状态或渲染的请求。这种设计思路导致编程时需要时刻考虑许多状态，而每次进行渲染都要更改若干个状态。为了更方便地管理这些状态，我在 Dandelion 框架实现中对 OpenGL 略作封装，屏蔽了大部分细

当我有了初步的需求分析结果，下一步就可以开始写代码了。虽然当初动手实现之前已经有了一些思考和设计，但后来写出的代码还是有不少问题。这一篇文章回顾最初对代码结构的设计，其中有很多粗糙的地方后来被大幅度重构，但事件循环和交互处理的部分还是大致留存下来了。

和同学聊天时开玩笑说，建设一门课就好像养了一个孩子，时时处处需要关心。今年我为本科的图形学课程编写了全新的实验框架，也算是慢慢走出了完全模仿 CMU 15/462 的阶段，试图更好地在有限的教学条件下展现图形学的趣味。其实在此之前我并未写过如此规模的程序，完成框架的过程也因此成了锻炼自己的过程。如今框架初成，用这几篇文章回顾和总结一些设计与开发的经验，既是一段给后来开发者的说明，也是记一些自己的小

不幸上了一门干瘪枯燥的形式化方法课程，但课讲得不太好并不影响这些知识的趣味，毕竟还可以自己学嘛。课程内容更偏向软件形式化验证，不过会补充 λ 演算的内容，并且用到的证明器 Coq 也比较像是一种函数式语言。而相比于形式化验证，我对 λ 演算和函数式编程的兴趣更多一点。借着几篇博客和一些视频资料了解 λ 演算是什么之后，我也写下了几页的草稿和笔记。这里再整理一下自己的思路，从原始的 λ 演算系统开始
