将菲利普斯展馆的几何结构转化为可演奏的音乐，实现建筑到声音的逆向生成。
Extending Xenakis: From Architectural Geometry to Sonification of the Philips Pavilion
- 从建筑表面提取生成线，反向生成连续音高滑奏。
- 3357个采样点生成五个能量块与稀疏管乐序列。
- 适合对建筑声学、交互音乐感兴趣的跨学科研究者。
建筑与音乐通过比例和时间结构相连，但建筑几何很少被视为生成音乐的来源。本文逆向重构申克尼斯从《元气》中的弦乐滑奏到菲利普斯展馆曲面的转化过程，将建成的展馆作为时间性作品进行声学转化。通过重建展馆为九个直纹面，提取其生成线，并在每个面上划分结构线与空间采样点。每面四个均匀分布的生成线生成连续弦乐滑奏，3357个采样点构成五个基于密度的能量块及稀疏铜管与木管乐段落。系统以Python实现，输出MIDI并在Ableton Live中渲染，配合实时3D可视化，展现建筑的运动、静止与结构对比。本研究为建筑几何转化为可演奏音乐结构提供路径，拓展了申克尼斯的建筑与音乐思想至声学化与互动音乐实践。
原文摘要 · Abstract (English)
Architecture and music have been linked through proportion and temporal structure, yet architectural geometry is rarely viewed as a source of generative music. Revisiting Xenakis' one-directional transformation from string glissandi in Metastaseis to the ruled surfaces of the Philips Pavilion, we invert this workflow and sonify the completed Pavilion as a temporal composition. We reconstruct the Pavilion as nine ruled surfaces, extract their governing ruling lines, and subdivide each surface into structural lines and spatial sampling points. Four evenly spaced ruling lines per surface generate continuous string glissandi, while 3357 sampled points develop five density-based energy blocks and a sparse brass and woodwind subsequence. Implemented in Python, the system produces MIDI rendered in Ableton Live, accompanied by a real-time 3D visualization that reveals architectural motion, stasis, and structural contrast through sound and image. In general, this work paves the way for the transfer of architectural geometry as a performable musical structure, extending Xenakis's architectural and musical thinking to sonification and interactive music practice.
