A texture refers to the characteristics of a surface and the appearance of an object. A texture is generally described as being smooth or rough, soft or hard, or, matt or glossy. The lacking of in-class tools has been a challenge for design students in learning to choose the suitable texture with the 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 conventionally use static rendered images and photographs in conjunction with lecture sessions. In this paper, we present our findings from a pilot study that was conducted on architecture and interior design students. Specifically for this study, we developed an interactive Virtual Environment utilizing a next-generation 3D Game Engine. Computer graphics technology, especially the ones employed in many next generation video games (such as developed for the Xbox360 and Playstation 3), allows for realistic game environment to be displayed on the TV screen. The Virtual Environment in this study utilizes an image-texturing technique known as bump-mapping that allows for more realistic material representation. Real-time dynamic lighting was also used in the Virtual Environment. This paper also describes the development process of the interactive Virtual Environment to support photorealistic 3D textures in combination with different lighting conditions.
