Virtual molecules, rendering speed, and image quality
In this paper we present a system for investigating molecule data by means of Virtual Reality techniques. This allows new insights into the structure of individual molecules as well as into the interaction between multiple molecules. Scientific Visualization, especially when performed in Virtual Environments, must consider two opposing demands: Maximum image quality at sufficient frame rates. With this in mind we discuss a general scheme for determining the quality of (3D) graphical computer systems. For this scheme, we are focusing on the user's perception of the system. Therefore, we do not include factors like memory size or processor speed directly, even though they may influence other features which we consider crucial for Graphics System Quality (GSQ), e.g., rendering speed. We identify three components of Graphics System Quality: Data quality, image quality, and interaction quality. We show that our system for immensive investigation of molecule data is unique in its advanced co mbination of image quality and interaction quality.
