![]() |
The iVolume tool allows you many options to manipulate your existing volume displays. Once you have visualized your volume data, you may rotate, translate, scroll, and zoom as well as modify volume properties. The following options are available for manipulating volumes.
Rotating makes it possible to rotate the volume within the visualization without affecting the rest of the data space (graphical objects and axes). To rotate your volume, from the toolbar on the iVolume window, select the Rotate button. For more information about rotating, see Rotation.
It is possible to scale the data within a volume by a specified scale factor. To scale your volume, select Operations Transform
Scale Data. For more information on scaling data, see Scaling.
View Zoom allows you to zoom in or out on a specific area of the volume display area. To zoom in or out in View Zoom mode click Zoom on the toolbar. For more information on working with View Zoom, see Zooming.
Canvas Zoom allows you to increase or decrease the magnification of the entire display canvas (which may contain multiple views, depending on the layout) by a specified percentage. Canvas Zoom is available by selecting the pull-down percentage list from the top of the tool just under the Help menu. For more information on working with Canvas Zoom, see Zooming.
Annotations can be added to label or describe volume visualizations displayed in the iVolume tool.
