浮光掠影—動態光影創作研究

Abstract

「浮光掠影」，指像「物體表面反射的光」和「一閃而過的影子」，都是指虛幻而難以深入觀察的事物。而人生就像浮光掠影般，虛幻不真實的感覺，也可詮釋現代社會因為資訊的多元，只了解表面、膚淺而不夠深刻仔細。科技藝術是近年發展的趨勢，本研究藉由科技藝術的手法，來表現浮光掠影形而上的抽象概念。其中，光影─變化的創作歷程主要是以「構成（Gestaltung）、轉化（Transform）、結果」為主軸；研究者藉由文獻回顧幾何造型的基本結構，並延伸探討柏拉圖立體來提升作品的寓意和視覺的表現。另外，幾何造型結合光影的「時間（Time）、空間（Space）、媒介（Medium）」不同元素的轉換下，不同的方式來呈現，例：動態影像和靜態的作品等，讓觀者在觀看過程中產生視覺錯視的效果與體驗。

因為希臘哲學家亞里斯多德認為，數學與幾何才是最純粹和永恆的，本創作利用幾何造型來呈現具有複雜的結構的圖像；在藝術上幾何造型的運用非常頻繁，從建築到家具等，都與生活非常貼近，所以可從東方與西方的幾何造型思維來分析符號寓意與運用至作品表現上。

從榮格心理學中提出曼荼羅（Mandala）的原型象徵來討論為主，曼荼羅是透過圖像來表現形而上學的觀念，從宗教和哲學的角度來增加觀者對圖像與造型內涵的了解；光影創造出時間與空間，主要是在不同媒介產生出不同的效果，與幾何造型的基本結構一樣會讓視覺產生錯覺，所以將此兩種元素結合，利用不同條件和限制，應用到視覺創作的表現上。

本研究創作的方式主要將「光影」加入「動態」的元素，分別用「手動、光動、心動」，這三種方式進行表現。手動：經由互動裝置觸碰或是利用手機軟體QR Code程式等方式，透過科技媒介與觀者的互動過程中產生連結。心動：運用幾何造型基本結構的平面作品，在移動的過程，透過視覺變化讓觀者心理產生對空間的錯覺將二維平面的創作變為三維立體的效果。光動：利用光是觀者無法控制的因素，作品透過燈光閃爍或是動態影像的投影過程，讓觀者產生遺像（After-image）的效果。此研究創作將以思考「光影」與「幾何造型」的結合，呈現出不同的視覺效果與未來發展可能性。

“Fleeting Lights” refer to "the lights reflected by a surface" and "fleeting shadows," both of which are too surreal to be observed in depth. Our life resembles fleeting lights in that both are surreal and unreal, depicting life in the modern society having abundant sources of messages but they are at best superficially consumed due to their vast number. Techart is the trend in recent years of development. The current study adopts the techniques of Tech-art to represent the abstract, metaphysical concepts of fleeting lights.

The procedure of this project is mainly composed of three main steps: formation, transformation, and the final products. The researcher reviewed the fundamental constructs of geometric shapes using literature review and then further explored Platonic solids to capitalize on a variety of strengths to raise the meaning and representation of the works in this study. In addition, polyhedrons can be manifested differently based on the “time, space, and medium,” three elements of light art. For instance, dynamic images and static works create the effects of optical illusions for the audience while observing them. The current project’s works are designed using polyhedrons to represent complex structures because according to Greek philosopher Aristotle, mathematics and geometry are the purest and eternal. Geometry is frequently adopted in art, ranging from constructions to household appliances, highly related to everyday life. Thus, one can analyze polyhedrons and geometric shapes from the viewpoints of the east and the west and to use those concepts to related works. In the perspective of psychology, Jung also proposed the prototype of Mandala that visualizes metaphysical ideas through the images of religion and philosophy. The sense of time and space can be created through lights using different media of representation, which is the same case with geometric shapes in that both can create optical illusions. Hence, the current study combines the elements of media and geometry in its visual art.

The technique adopted by this thesis is fusing lights with dynamics and the researcher represents them using tactile, optical, and perceptual transactions. Tactile interactions are achieved by creating interactions between the audience and the works via interactive touch-screen devices or smartphones’ Quick Response (QR) Codes. Perceptual interactions are accomplished by creating three-dimensional effects using two-dimensional geometric works to construct such perceptual illusions. Optical interactions are the results of blinking lights or dynamic images, things beyond the control of the audience, to produce after-image effects for the audience. This study combines lights and geometric designs to create different visual effects and the accompanying possibilities.
