The advent of the Virtual Reality Modeling Language (VRML) as a portable file format for describing three-dimensional (3-D) scenes has created the ability for researchers, educators and students to share anatomical models on the WWW. The implication for medical teaching is that students can interactively examine anatomical structures and their 3-D spatial relationships, using current personal computer (PC) technology. The work of this thesis creates, for the first time, a high-resolution middle-ear model that is accessible on the World Wide Web (WWW). The 3-D model is created by automated aligning of the source images (histological sections), interactive segmentation, and 3-D surface reconstruction. The resulting model is translated into VRML format. Images of the histological sections can be superimposed on the model, allowing students to view a section in its 3-D context. To enhance the viewing of these scenes, a VRML browser is modified to support transparent rendering of surfaces. Finally, a WWW interface is designed to allow users to selectively choose the model structures, section images and associated viewing parameters, in order to build their own 3-D scene.
