We present a haptically enabled immersive environment for the segmentation and visualization of volumetric data. The environment uses a client/server design and allows multiple, remotely separated users to work in a shared visual space. The environment incorporates several distinct segmentation methods that are based on the local application of computationally expensive algorithms and provides the user with continuous fine-grained control. The environment uses haptic feedback to both provide a sense of touch for segmented structures and to provide additional user control over the segmentation algorithms.
