The pages of the dissection kit are organized into an introductory Workstations used to perform graphics rendering. To have a minimal impact on the http server, and on the To be usable over low-bandwidth networks,Īnd with a variety of browsers. Given this data set and the graphics tools to interact withĪnd to present it, the Web pages for the dissection kit were Provided a ``mask'' representing each organ. Subsequently, semi-automatic segmentation (isolation Of the frog internals as roughly 10,000,000 tiny Each slice was photographedĪnd digitized thereby providing a representation Provide sufficient resolution, due to differences between Surface and/or volume rendering software. Structures of an animal starts with buildingĪ voxel data set (voxels are small cubes - the 3D equivalent of pixels) Obtaining a 3D data set that represents the internal With their original relationship to each other, and then add the smallĭifficult if not impossible in an actual dissection. One can look at the stomach and skeleton by themselves, May be examined in their undisturbed relationships to each other. Of the internal 3D structure of animals in a way that physicalĭissection can only imply: organs and structures Using a virtual dissection approach provides a realistic representation In combination with the second point, this means thatĮnd users do not necessarily require high-performance rendering systems The back end computation can take place on as complex and powerful a To provide a uniform interface to another class of applications:
The teaching of biological sciences - specifically, the anatomy Idea is to show how image-based applications can be applied to At the sameĪpplications can introduce students and teachersĬomputer and networking capabilities, and encourage them The K-12 curriculum in a variety of disciplines. Sophisticated image-based applications can enhance The ``Whole Frog'' project is designed to show how This work is intended to demonstrate three uses for Web technology: Image, it passes the location of the image file and controlīack to the script which rewrites the image on the client.Īwkward, the overall process is quite similar to howĪll rendering systems work, with the image being written intoĪ local frame buffer, or sent across the network as an X-window When that process completes generation of the Machine to accomplish the graphics rendering of a large 3Dĭata set representing the frog and its internal organs. An advantage to this technique, as opposed to dissectingĪ real frog, is that undissection is as easy as dissection.Ĭontacts a continuously running process on a more powerful View the frog from above, with the exterior and skeleton Press ``form'' buttons that indicate that he or she wants to With the different anatomical structures visible or invisible.
