產品表現技法之倒影應用研究

The Application Study of Reflection in Product Rendering

電腦繪圖之基礎與觀念建立於傳統之表現技法，然概念設計仍需大量依靠手繪表現，故表現技法並未因電腦繪圖軟體的研發及技術與應用之普及而遭淘汰，反而更應加以重視，以避免實際運用時之困擾與偏差。坊間表現技法的相關書籍多側重粉彩、麥克筆於對象物上著色過程的介紹，一般的透視書籍則偏重說明對象物在地面、桌面或牆面上產生倒影的情況，對於對象物本身因環境物反射光線之影響而於自身產生倒影的相關理念則明顯的缺乏。 本研究首先針對銘傳大學商品設計系學生，實施影響表現技法學習成效的原因調查，對學生於倒影學習方面作統合性研究，就學生於學習上之問題點，藉由相關文獻與理論之整合，以簡易的圖解方式補充教學資訊之不足，使手繪概念展示圖，於快速設定倒影以表現光澤效果時有脈絡可循，並加強電腦繪圖基本概念之認識，以期對教學上與政府推動產業之升級均有所助益。

The fundamental concepts of computer graphics are based on traditional presentation drawing, however, it hasn't been eliminating through computer technologies and applications; instead, more emphases should be put on to prevent the aberrations in actual practices. Current books of presentation drawing mainly focus on the process of coloration, scenography publications stress reflections on ground, tables or walls. References about the inverted images result from reflex illuminant to object itself are obliviously inadequate. This study probed the students' learning outcomes of presentation drawing at the Product Design Department in Ming Chuan University for the overall research of reflection learning. With references and theories related to the subject in a simple graphic method try to supplement the shortage of teaching information in various learning aspects. Therefore, locating the reflection can be easy in accordance with the manual drawing concept exhibit and understanding more about the basic computer drawing. We consider it advantageous to both learners and industries upgrading promotion.
