The 3D Atlas reconstructions allow users to view 3D cochlear models created from complete 2D image stacks. The MCD has a variety of reconstructions available for viewing; including reconstructions of the normal CBA/J mouse cochlea and the mutant C57BL/J COL4A5 mouse cochlea. While most of the reconstructions are available for viewing as QuickTime VR Movies, some individual cochlear reconstructions are ... available for viewing using the EPL 3D Viewer. Both QuickTime and the EPL 3D Viewer are available as free downloads.

The virtual reality files in the first edition of the 3D Atlas of Ann Arbor were all made using a strategy involving Geographic Information System (GIS) software coupled with 3D graphic design software. The process was effective but often time-consuming and the files created were quite large. Indeed, in the latter vein, alternative strategies, such as linking one file to another in a hierarchical pattern were employed so that the reader never had too large a file on screen at a single time. Another issue involving the creation of these files was cost of the software. The process involved many thousands of dollars worth of software (and of time of experts using the software). Small cities had faint hope of being able to maintain a state-of-the-art 3D system without substantial donations of time, software, or both.

The 3D Tooth Atlas is a software-based virtual environment that allows users to examine the morphology of the human dentition in full three-dimensional clarity. Each tooth can be rotated in three axes, rendered completely transparent to expose the structures of its complex anatomy, and studied from all angles as well as from the inside out. This version includes all of the features that made the previous version so popular—models of all 26 primary teeth with interactive slide bar to reveal their eruption by age; highly annotated segments of the mandible and maxilla (ie, bones, teeth, and pulp) that can be viewed independently or together from any orientation (eg, through the sinus); three-dimensional views of all anatomic structures relevant to endodontic access and treatment; a mock National Board exam provided by the ADA; annotated view of the entire skull; and the official, unabridged edition of the Glossary of Prosthodontic Terms. The latest version ... features a number of new enhancements, including an expanded library of teeth, now comprising more than 300 interactive three-dimensional models; a larger collection of skull models, including several with mixed dentition; an expanded pedodontics section; and animated drawings and movies that demonstrate techniques for file cleaning of root canals.

[One] immediate goal is to create a 3D voxel atlas of the C57BL/6J mouse brain from the present 2D section images. The critical factors are alignment of section images and matching of stain intensities, because their precision controls the efficiency and accuracy of 3D segmentation. The 10 micron images have been aligned semiautomatically with newly written VoxelMath software, followed by small further manual adjustments using pixel-based visual landmarks. Full cell- and myelin-stained mouse brains have been constructed. Further refinement of the alignment of serial images is anticipated, and should precede final segmentation of gray and white matter structures. Differences in staining intensity from section to section may be hardly noticable when one studies sections in the standard manner, but the differences become very important during 3D reconstruction.

This "3D atlas" can be used to generate VRML depictions for selected regions-of-interest on Mars. A Java servlet is used to build VRMLs using elevation data from the Viking-era Mars Digital Terrain Models (DTMs). The resulting elevation grid is texture-mapped using images from the Viking Mosaicked Digital Image Models (MDIMs).
