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

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 visualization of the frog data set demonstrates the potential of the Web.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. To view various parts of a frog from many different angles, and (CGI) capability of WWW servers to provide an interactiveģD visualization front end through Web clients. To be an easily used and powerful front end for high-performance computing resources. (3) to show the possibility for the Web and its associated browsers (2) to show the feasibility of interactive visualization With the ability to explore the anatomy of a frog with a virtual dissection We have developed a set of techniques for providing interactiveģD graphics via the World Wide Web (WWW) as part of the Hyperlinks have been updated periodically to replace stale links. Published in Proceedings, The Second International WWW Conference '94: The frog dissection experiment applied in the virtual environment was accepted by the majority of the pre-service teachers who stated that they would prefer virtual dissection tools.Virtual Frog Dissection: Interactive 3D Graphics Via the Web Virtual Frog Dissection: Interactive 3D Graphics Via the Web David Robertson, William Johnston, and Wing Nip Imaging and Distributed Computing Group Lawrence Berkeley National Laboratory According to the findings, the observations made during the chicken embryo development process emerged negatively due to ethical and moral concerns as the development process progressed. The content analysis method was used in the analysis of the data. Then, due to the COVID-19 pandemic, the frog dissection experiment was conducted as a virtual dissection. The implementation started with observing the chicken embryo development process that the students actively carried out. An open-ended question form and student diaries were used as data collection tools. The study group consisted of 36 students, 29 female, and seven male. This case study aimed to determine pre-service science teachers’ views of hands-on dissection and virtual dissection. Different opinions have been noted in studies on this subject, and various applications are recommended according to education levels.
It is a controversial issue in education that students perform dissection experiments.
