7 - 4   Three-dimensional Plot Control

You can view any type of data as a 3D plot by selecting 3D Cartesian from the plot type drop-down menu in the Plot sidebar. IJK-ordered data and finite element volume data are displayed in 3D automatically.

Three-dimensional plots can be manipulated with the following controls, which can be accessed via the Plot menu:

• Reset 3D Axes - Reset the 3D axis sizes and the 3D origin of rotation.

• Three-dimensional Axis Limits - Control the data and axis aspect ratios for 3D plotting.

• Three-dimensional Orientation Axis - Control the optional 3D orientation axis, which displays the current orientation of the three axes in the workspace.

• Light Source - Control the light source position, as well as the intensity of the light, the background light, and the surface color contrast. See Section 13 - 4 “Three-dimensional Light Source” for more details.

• Advanced 3D Control - Specify the default lift fraction for 3D lines, symbols, and tangent vectors, as well as the 3D sorting algorithm for the plot.

The following controls can be accessed via the View menu.

• The Rotate Dialog - Control the 3D orientation of the plot.

• Three-dimensional View Details - Set the specifications for parameters affecting the 3D display of your plot, including the perspective, field of view, angular orientation of the plot, and view distance.
