Quicktime VR: Figures

To interact with the object, hold down the mouse button and drag the hand over the object. Rotational control is in the horizontal axis. When the hand passes over a frame containing a hot spot it changes into a white arrow pointing into the frame (only when the mouse button is not held down). Click to jump into the hot spot.

The hot spot is located on frames 8 through 11. Clicking on the hot spot presents a second QuickTime VR movie illustrating the aperture of Elphidium crispum through increasing orders of magnification. Control is in the vertical axis. There are hot spots on frames 1 through 4 and frame 21 to jump back to the global view of Elphidium crispum.

FIGURE 3. Elphidium crispum (Linné). A, B as illustrated by Fichtel and Moll in 1798, C, D as illustrated by Williamson in 1858, E, F as illustrated by Brady in 1884.

FIGURE 4. Elphidium crispum (Linné). A, B, C as illustrated in the typical fashion for publication.

FIGURE 5. The long axis of Elphidium crispum was chosen to be the Y-Z plane and was mounted vertically on the SEM stub (represented here in dark blue). The initial images were captured in the X-Z plane (light blue oval). Images were captured every 18° in this plane for a total of 20.

FIGURE 6. To make a QuickTime VR object that can be manipulated from any perspective it is necessary to capture the object from a variety of angles in the Y-Z plane (light blue arc). This figure illustrates positions separated by increments of 22.5° in the Y-Z plane. At each position in the Y-Z lane the sample is rotated through 360° and captured. Note in SEM work the stage moves and not the electron gun.
