3-D Plot Windows

3-D Plot Windows display a 3-D surface of 2-D image data. The , which is often a plot of image intensity versus position. The topic 3-D Pixel Representations shows how a 2-D image can be rendered various ways in 3-D for a better view of the data. You can control whether Mira prompts you to confirm closing a 3-D Plot Window using the check list item in the General Properties dialog. See 3-D Surface Plot for a general overview of 3-d plotting.

Components of 3-D Plot Window

The diagram below shows the general 3-D Plot window. In this case, an image set is plotted, making the Animation Bar visible at the bottom of the window. This toolbar that provides controls for plot sequencing. The Rotation Toolbar at the top is generally available for any 3-D plot.

Toolbars

Viewpoint Rotation

The Rotation Toolbar controls rotation of the rendered data. This is similar in function to the Plot Animation Bar except that this toolbar adjust Properties for rotation rather than for changing between plot series.

Plot Series Animation

The 3-D Animation Control Toolbar toolbar works with multiple 3-D plots created from an Image Set displayed in an Image Window. when an image set is displayed in an image Windows, use the [G] button or the Plot Image Set command to choose whether to render in 3-D only the current image or the entire image set. If you render the image set, then this toolbar is automatically opened.

The Color Map

Like Image Windows, 3-D Plot Windows have a Color Map on their right border. This shows the mapping of palette entries to display levels for the rendered surface. Also as for Image Windows, you can change the palette mapping by stretching the palette using the Color Map or the Palette Properties dialog.

• To stretch the palette from the Color Map, move the arrow over the Color Map, mouse down, then move the mouse without releasing the left mouse button. When you release the mouse button, Mira leaves palette stretching mode. You can also adjust the palette from controls in the Palette Properties dialog.

• To open the Palette Properties dialog, double click on the Color Map or use the View > Palette Properties command.

• To reset the current palette to original settings, right double click the mouse on the Color Map.

Adjusting the Z Axis Scaling of the 3-D Plot

The range of the Z axis can be adjusted, if desired. You can change the scaling interactively or by entering the minimum and maximum Z values. [ examples]

• Specify the Z range: Use the View > Z Range > Set Limits command to open the Surface Plot Z Limits dialog

• Open the 3-D Plot Context menu and execute the Z Range command.

• Autoscale the Z Range: Use the View > Z Range > Autoscale command or the similar command from the 3-D Plot Context menu. This resets the limits to the values when the plot was originally created.

To interactively stretch the Z range, regardless of which way it is specified, move the vertical slider on the right border of the 3-D Plot window.

Changing Plot Properties

The 3-D Plot has a number of attributes that can be changed to give you a more meaningful view of the data. Attributes are changes from various windows belonging to the 3-D Plot group. These attributes include the type of plot, the way the 3-D facets are represented, the drawing of projection planes and axes, colors, fonts, viewpoint, and the properties of the illuminating light source. See the following sections for more information on changing these attributes. These commands are available from the 3-D Plot menu bar and the Context Menu:

• The 3-D Drawing Attributes dialog allows you to change the drawing attributes and save them for other plots.

• The 3-D Viewpoint tool window adjust the viewing location relative to the data.

• The 3-D Window tool window changes the colors and fonts used for drawing the plot.

• The 3-D Light Source tool window controls the illumination used for Phong Shading in the Illuminated Surface plot.

• See 3-D Pixel Representations to view some of the variations.

3-D Plot Context Menu

The Context menu contains options for changing the way the image data are rendered and for altering the appearance of the window.

• Open the 3-D Context Menu the way you open the context menu of any view window: right click on the window interior.

Accelerator Keys

Accelerators in the table below are enabled when a 3-D Plot Window has focus.
