摘要

以空間形式呈現美感為主的室內設計，慣用3D繪圖的室內設計師，已普遍將3D繪圖運用在設計發展過程中，在虛擬空間中進行設計思考，繪製出空間感、分割比例、燈光效果及材質搭配等，皆能在設計發展時以渲染出的3D效果圖呈現，利用視覺思考進行設計調整，藉此提高設計發展過程的效率及設計思考結果的準確度，並表達出設計構想。

本研究問題在於軟體應用產生出的擬真度差異，將影響繪製過程中的視覺思考與行為模式，進而相對的影響設計發展過程中的流暢度與精準度，因此本研究目的為了解不同軟體之間的擬真度差異，運用案例進行問卷調查法，調查不同3D繪圖軟體之間的擬真度差異，以及驗證運用感知行為判斷擬真度的視覺思考方式；而探討擬真度差異如何影響視覺思考，再運用口語分析法進行實驗，利用編碼系統分析繪製3D效果圖的步驟中，渲染結果的擬真度影響受測者的反應與決定，藉此了解擬真度的差異是如何影響設計發展過程。

本研究範圍限制在設計階段前期的概念發想之後，進行深化與發展的單人操作過程，運用3D繪圖協助設計思考，觀察渲染結果判斷美感與合理性；3D效果圖以往運用在設計階段完成之後，藉此提高溝通與表達的效率，而在本研究中是協助設計發展的角色，利用檢視擬真度的呈現，進行視覺思考的3D繪製過程。

本研究分析結果明確指出，室內設計中普遍使用的3D繪圖軟體之間的優缺點及造成不同的擬真度，更確立了感知行為在檢視3D效果圖時，所運用的邏輯與方式，而口語分析法的編碼結果分析中，指出受測者在繪製過程中，每段的步驟運用的視覺思考與行為模式，進而了解視覺思考行為如何影響3D設計過程，以提高擬真度的方式，降低繪製過程中的思考與判斷時間，並達到符合設計者所思考的內容，利用3D效果圖加以精準的表達設計。

Abstract

Interior design mainly uses spaces to present the concept of beauty. Interior designers who are accustomed to using 3D drawings have been bringing it into the process of design development. Designers think and construct their designs in a virtual space to map out the sense of space, the split ratio, effects of lights, the combination of different materials, etc., which would help to create 3D renderings when developing a design and make adjustments accordingly through visual thinking. This in turns increases efficiency during design development and the accuracy for the results of design thinking and thus successfully convey design ideas.

This research discusses the differences in fidelity between software. Fidelity would affect visual thinking and behavioral patterns during the drawing process which would further affect the fluency and accuracy in design development. Therefore, the purpose of this research is to better understand the differences in fidelity among various software. To achieve this, cases and questionnaires are used to look into the differences in fidelity among different 3D drawing software, and verifications on how visual thinking is used as perceived behavior to determine fidelity are presented in this research. Furthermore, protocol analysis is used to experiment how the differences in fidelity affect visual thinking. Using the coding system to analyze the steps when producing 3D renders and observe how the fidelity of rendering outcomes affects respondents’ reaction and decision, how the differences in fidelity influence the design development process is better understood.

The scope of this research is limited to the first stage of the designing process, which is after designing concepts are being developed, and the deepening and developing process of a single person. 3D drawings are used to assist in design thinking in order to observe the rendering result for determining the sense of beauty and whether it is reasonable. 3D renders are generally used after designs are completed to better the efficiency in communication and expression. However, 3D renders act as a role which assists in the design development in this research; through observing the fidelity presented to trigger visual thinking in order to progress with the 3D rendering process.

The results analyzed by this research clearly identifies the pros and cons of various 3D drawing software that are commonly used in the field of interior design and also the differences in fidelity produced by software. In addition, the results also confirm the logic and methods of perceived behavior when looking at 3D renders. Additionally, the analysis of the coding results of protocol analysis also indicates respondents’ visual thinking and behavioral patterns of each step when drawing. Thus, this research realizes how visual thinking behavior affects the 3D designing process. Through higher fidelity, the amount of time for thinking and making decisions are reduced when drawing which makes the design presented to be aligned with the contents which the designers have in mind. As a result, using 3D renders can express one’s design more accurately.
