23. Hyperwood – Open-Source Furniture (hyperwood.org) 109 points | 7 comments | by panic

Hyperwood – 开源家具项目总结

项目核心理念

  • 强度与稳定性：采用分层板条结构，类似工程胶合层积木材，使家具具有高强度、抗翘曲和稳定性。
  • 设计哲学：受舒马赫《小的是美丽的》启发，强调可持续性、本地韧性和通过简单技术赋能个人。
  • 开源传统：继承恩佐·马里的“自设计”理念，推动家具制作民主化，鼓励动手实践、设计素养和协作创新。

Hyperwood交换格式（HEF）

HEF是专为Hyperwood生态系统设计的文件格式，基于线段（而非体素）作为基本元素，促进不同软件和应用间的数据标准化交换。

数据结构

HEF文件分为三部分：

  1. 头部：包含格式标识、版本、网站链接、模型名称、生成参数（JSON格式）、板条规格及计算属性。
  2. 部件映射：列出所有部件名称（如板架、座椅、龙骨、腿），通过索引标识，名称长度不超过32字符。
  3. 板条数据：每行记录一块板条，包含：
    • 位置（X:Y:Z坐标）
    • 向量（各维度长度）
    • 层号
    • 部件索引（对应部件映射）

示例说明

文件以标准化头部开始，接着是模型参数和部件列表，最后逐行列出板条数据。例如，一个长凳模型可能包含多个板条行，每行定义其空间位置和所属部件。

关键特点

  • 开源与可扩展：鼓励社区参与设计和改进。
  • 技术标准化：HEF确保设计数据的一致性和可移植性。
  • 实用导向：聚焦于可亲手制作的家具设计，降低技术门槛。
