QuickTime VR

 

The panoramic image show below is "stitched" from three SEM images of Redondo Beach (CA) Diatoms taken at a magnification 0f 100X. (The selected diatom on the right will be a "girdle view" - possibly Eupodiscus. The left-hand example is probably a foramina fragment rather than a diatom.) The image is then "run through" Apple's QTVR Authoring Studio which converts it into a fully functional QuickTime VR panoramic movie with a 120 degree arcs. Click here to go to a "comments" page.

The QTVR movie is shown below. There is a menu in the lower left corner. Clicking on the panorama with your cursor and then moving it around will allow you to "search" the image. If you click on the + sign the area in view will be enlarged. The minus sign will bring you "back out". If you click on the ? mark then any "hot spots" in the movie will be shown. These "hot spots" can be links to other panoramic movies. (You will also notice that the "bulls eye" cursor changes to an arrow whenever it encounters one of these links.

There are other ways to link panoramic images. In the image below of the Academy Building there is a "hot spot" link on one of the windows. This link will take you to a URL.

The panoramic image below is of the salt water aquarium in the Science Building. Further information on the Science Building can be obtained at the following site.

It is also possible to produce 360 degree objects with QTVR. The panoramic image below is of a loggerhead sea turtle. The panoramic was created by stitching together a number of still shots of the turtle skull as it was rotated on a table. Further information on this skull can be obtained at the following site.

This page also contains the WEB version of ImageJ. This is an applet that launches in a separate window from the WEB page. If you go up to File. Open Samples you can load anyone of the four Diatom SEM images. These images have their original "micron" scales. If you also open the image "Calibrate" it will have directions on how to calibrate these images and thereby measure the diatoms.
