A Study on Visual Perception of 3D Texture
A texture refers to the characteristics of a surface and the appearance of an object. It is generally described as being smooth or rough, soft or hard, matt or glossy. Inadequacy of in-class tools has been a challenge for design students in learning to choose correct texture with right lighting condition for a specific space. The learning experience of architecture and interior design students in this subject matter can be enhanced through the use of interactive virtual environment. Using an interactive virtual environment can enhance the present teaching methods that mostly use static rendered images and photographs in conjunction with lecture sessions. In this paper, we present our findings from a pilot study that we conducted on the visual perception of texture depths (3D texture) used in different lighting conditions. The data for this study was gathered from an experiment conducted on students of architecture and interior design major. Specifically for this study, we developed an interactive VE utilizing a next generation 3D Game Engine. Computer graphics technology especially those employ in many next generation video games (such as the ones developed for the Xbox360 and Playstation 3) allows for realistic game environment to be displayed on the TV screen. The VE also utilized an image-texturing technique known as bump-mapping to allow a more realistic material representation. Real-time dynamic lighting was also used in the VE. This paper also describes the development process of the interactive VE to support photorealistic 3D textures in combination with different lighting conditions.
