本研究嘗試了解人類視覺感知系統的運作，以及分析視錯覺在二維平面與三維空間的特性與表現；並使用一套電腦運算工作流程，結合物理基礎彩現、知覺基礎色調對映、立體圖像合成技術以及立體屏幕顯示，進而產生一種數位圖像環境。此數位圖像環境可以在電腦顯示器屏幕上，模擬與視覺化呈現出光與空間藝術團體的特殊作品效果。並且按照數位運算模擬下的數值條件，以實體的空間裝置模型製作，來檢證整合數位模擬輔助設計光環境空間的可行性與準確性。因此，利用上述數位圖像環境的工作流程與呈現方法為基礎，結合心理學上的視錯覺研究理論，進一步模擬試驗與設計出特殊的光與空間之場域特定藝術空間裝置，探究光線在建築空間設計思考上的豐富想像。 Visual perception is the primary sense humans utilize to perceive the space and environment around them. However, visual perception does not always deliver true information. Optical illusions occur because of ambiguous perceptual judgments of visual information, and can be observed in the visual perception of both 2-D planar and 3-D spatial systems. Because these illusions can be impactful to people who have normal vision, it has been utilized as one of the design parameters for art and architecture.
Light is one of the essential factors that contributes to the intangible characteristics of an architectural space, and it is also the primary intermediary that induces visual perception. Many artists of the Light and Space modern art movement have been using light as both a material and a medium to create art installations that provide specific visual and spatial perception. This art installation method involves complex site environment interaction and trial and error remain as the primary design methods. Additionally, the exhibition is often restricted to the physical site.
This thesis presents an innovative approach for utilizing light, and visual illusions resulting from the perception of light, as parameters to design a three-dimensional space through a computer-aided design process. A computational workflow that employs physically-based rendering, perceptually-based tone-reproduction, and stereo display technology to assist the design process of art installations that utilize light and illusion was explored and validated. To conclude the study, a site-specific art installation with architectural scale was designed and evaluated employing this innovative computer-aided design tool.
