## Primary sections

- [About Chihyu Tsai](https://chihyu-tsai.com/about/): Profile, design approach, and selected work.
- [Portfolio](https://chihyu-tsai.com/portfolio/): Selected works in architecture, interior design, and visualization. Professional projects developed through practice, collaboration, and construction.
- [Lab](https://chihyu-tsai.com/lab/): Experiments, studies, and unfinished investigations. A place for testing ideas, workflows, and speculative possibilities.
- [LoopFlow](https://chihyu-tsai.com/loopflow/): A Rhino-centered design, documentation, and visualization workflow toolkit.
- [Creative](https://chihyu-tsai.com/creative/): Personal explorations in atmosphere, environment, and speculative worlds. Most images begin without a story or destination, simply lingering a little longer in places that exist only for a moment. Collected here as an evolving archive of light, weather, and imagined environments — fragments of scenes that were never meant to be built, only felt.
- [Fragments](https://chihyu-tsai.com/fragments/): Fragments is an archive of imagined worlds. Each image represents a single moment, a fragment extracted from a larger narrative. The complete story may never be told.
- [Professional portfolio](https://portfolio.chihyu-tsai.com/llms.txt): Selected projects, practice notes, systems, studies, and profile.
- [Fragments Editions](https://editions.chihyu-tsai.com/llms.txt): Bilingual digital art books derived from the Fragments worlds.

## Portfolio

- [逢甲大學資電館 FCU IEB](https://chihyu-tsai.com/portfolio/project_011_ieb/): The renovation of Feng Chia University’s Information and Electrical Engineering Building involved the planning of shared interior spaces throughout the academic building, including activity zones, informal lounges, and discussion areas.
- [住宅C Residence C](https://chihyu-tsai.com/portfolio/project_010_c_residence/): This residential interior and pre-construction modification project brings three apartments together as one home. Given the larger scale and more complex inherited layout, the process began by identifying unworkable elements in the previous scheme and reorganizing the residence as a coherent whole.
- [住宅K Residence K](https://chihyu-tsai.com/portfolio/project_009_k_residence/): This residential interior and pre-construction modification project combines two apartments into a single home. After reviewing the inherited scheme and identifying elements that could not be executed, the design was reworked around the residents’ needs and the actual spatial constraints.
- [吉光片羽 Selected Works](https://chihyu-tsai.com/portfolio/project_008_selected_works/): A collection of selected works drawn from multiple projects, bringing together built designs, unbuilt studies, and proposals set aside during development. Though not every fragment became a standalone project, each preserves a particular line of thought, experiment, or design decision.
- [逢甲大學共善樓 FCU Virtuosi Hall](https://chihyu-tsai.com/portfolio/project_007_fcu_virtuosi_hall/): FCU Virtuosi Hall is a new educational building comprising one basement level and one floor above ground, with the architecture designed by Kengo Kuma & Associates. The scope combined overall interior planning with the translation of the original design into buildable construction documents, including the practical demands of setting-out and on-site coordination.
- [逢甲大學女生宿舍 FCU Dormitory](https://chihyu-tsai.com/portfolio/project_006_fcu_dormitory_03/): This renovation of Feng Chia University’s female dormitory focused on shared spaces across selected floors, including areas for activity, rest, informal gathering, and dining rather than the residential rooms themselves.
- [逢甲大學男生宿舍 FCU Dormitory](https://chihyu-tsai.com/portfolio/project_005_fcu_dormitory_02/): This renovation of Feng Chia University’s male dormitory covered both the residential units and shared spaces throughout the building. In contrast to the light, warm palette of the earlier FCU Dormitory, dark grey and orange create a bolder visual identity for the campus residence.
- [興達電廠國際競圖 otsotm](https://chihyu-tsai.com/portfolio/project_004_otsotm/): Developed with colleagues for the Hsing Ta Power Plant international competition, the proposal began by examining an unfamiliar building type and the relationships between the site, its existing facilities, and the infrastructure that supports them.
- [逢甲大學精采學舍 FCU Dormitory](https://chihyu-tsai.com/portfolio/project_003_fcu_dormitory_01/): This new student residence for Feng Chia University involved the interior planning of the entire building, including a range of dormitory room types and shared facilities.
- [住宅T Residence T](https://chihyu-tsai.com/portfolio/project_002_t_residence/): This residential interior and pre-construction modification project reconsidered how limited floor area could be allocated more closely to the residents’ actual patterns of use.
- [海口四十二番地 Haikao No.42](https://chihyu-tsai.com/portfolio/project_001_haikao/): Located in Haikou, Pingtung, this small hotel was conceived as an integrated architectural and interior project, introducing a contemporary hospitality experience within the context of a rural township.

## Lab

- [From Drawings to Release](https://chihyu-tsai.com/lab/lab_007_loopflow_release/): LoopFlow 2.0 rebuilt relationships rather than buttons: markdown as construction drawings, multi-model review, and a Package Manager release that does not mix with 1.0.
- [From Prototype to Protocol](https://chihyu-tsai.com/lab/lab_006_loopflow_prototype/): LoopFlow 1.0 began as field research inside Rhino: whether schematic design, design development, and construction documentation could stay in one model, with automation that the designer still controls.
- [Building the System](https://chihyu-tsai.com/lab/lab_005_atlas_framework_3/): How editable sources, local tools, AI collaboration, validation, and publishing workflows allow ATLAS to grow as a maintainable creative system.
- [Designing the Experience](https://chihyu-tsai.com/lab/lab_004_atlas_framework_2/): How ATLAS uses navigation, attention, continuity, and authored sequence to support different ways of viewing without losing orientation.
- [The Purpose and the Container](https://chihyu-tsai.com/lab/lab_003_atlas_framework_1/): Why ATLAS exists, how Fragments became its first container, and how different forms of creative work found distinct ways to be viewed.
- [Street House Builder](https://chihyu-tsai.com/lab/lab_002_builder/): Taiwan’s streets are shaped by informal additions, extensions, window grilles, and signs. Added by different occupants at different times to meet changing spatial needs, these elements accumulate into an architectural expression that appears chaotic yet carries its own order and a distinct sense of vitality.
- [L-System Growth Study](https://chihyu-tsai.com/lab/lab_001_biomorpher/): Form holds infinite possibilities.
Beginning with the growth of a tree, this study translates branching patterns into a controllable set of generative rules, exploring how forms develop and transform as different variables are introduced.

## LoopFlow products

- [LoopFlow overview](https://chihyu-tsai.com/loopflow/intro/): LoopFlow 是一套以 Rhino 為核心、貫穿 SD（Schematic Design）、DD（Design Development）至 CD（Construction Documentation）的半自動化設計與文件工作流。它不是試圖取代設計者，也不是另一套封閉式 BIM 系統，而是在保留 Rhino 自由建模能力的前提下，讓模型資料、圖面與文件隨著設計發展持續流動。 在傳統工作方式中，設計修改往往伴隨大量重複更新：模型、圖面、標註、圖號、Render 資料需要分別維護。LoopFlow 透過物件資料追蹤與同步機制，將這些重複性工作交由系統處理，但保留人的判斷與控制。
- [LoopFlow series](https://chihyu-tsai.com/loopflow/): Built around the Rhino 3D model as the single source of truth, LoopFlow carries a project from schematic design (SD), through design development (DD), to construction documentation (CD). The wider LoopFlow series extends the same model data through two connected paths: 1. **Design & Documentation** — SD → DD → CD inside Rhino, from the 3D model to 2D Layout documentation  ( LoopFlow ) 2. **Rendering** — Rhino 3D Model → OctaneRender Sync / Blender Sync
- [LoopFlow for Rhino](https://chihyu-tsai.com/loopflow/lf/): LoopFlow 2.0 是一套以 Rhino 8 為核心、貫穿 SD（Schematic Design）、DD（Design Development）至 CD（Construction Documentation）的半自動化設計與文件工作流。它不是另一個 BIM 系統，也不要求使用固定範本或參數化流程；你仍然掌控每個步驟，LoopFlow 負責資料更新、圖紙同步與其他重複工作。 主要流程都在 Rhino 中完成，讓模型資料、圖面與 Layout 文件能隨著設計發展持續演進。LoopFlow 已在多個實際設計專案中使用，目標是保留 Rhino 的設計自由，同時減少設計變更後的重複整理。
- [Rhino to Blender Sync](https://chihyu-tsai.com/loopflow/r2b/): Rhino 端裝一份 `.yak`（內含 Blender Sync zip）。跑正式指令後，zip 會拷到「文件\LoopFlow\Rhino to Blender Sync」。 - **模型同步** — 從作業中的 Rhino 檔匯出乾淨 3dm；Blender 可更新幾何並維持既有材質 - **選取物件** — 把目前選取匯成另一份無材質 3dm，像 FBX 一樣累加進場景 - **相機同步** — 將 Rhino 作用視角同步到 Blender - **燈光對齊** — Rhino 燈光圖層上的 Point 位置，用來對齊 Blender 裡預先準備的燈與燈具 - **Box Projection** — Shader Editor 裡載入 PBR 貼圖、世界／物件座標，不寫 UV
- [Rhino to Octane Sync](https://chihyu-tsai.com/loopflow/r2o/): Rhino 端裝一份 `.yak`（內含 Octane Lua）。跑正式指令後，lua 會拷到「文件\LoopFlow\Rhino to OctaneRender Sync\lua」。 - **模型同步** — 從作業中的 Rhino 檔匯出乾淨 USDZ；Octane 載入後接材質，之後更新靠關再開 - **選取物件** — 把目前選取匯成另一份時戳 USDZ，自行載入當組件 - **相機同步** — 將 Rhino 作用視角寫出；Octane 套用一次 - **點位對齊** — Rhino `R2O::` 圖層上的 Point 與 Block，用來對齊 Octane Scatter 上的燈與家具 Proxy
