We describe the use of the weighted distance transform (WDT) to enhance applications designed for volume visualization of segmented anatomical datasets. The WDT is presented as a general technique to generate a derived characteristic of a scalar field that can be used in multiple ways during rendering. We obtain real-time interaction with the volume by(More)
Simulated environments are increasingly being used to evaluate human behavior in a wide variety of situations. These virtual environments are particularly useful in the study of behavior involving dangerous conditions. Quantifying the impact of these environments on the subject is essential to validate the efficacy of the simulation as a virtualization of(More)
