GMS:3D Grid Display Options
From XMS Wiki
Jump to navigationJump to search
The properties of all 3D grid data that GMS displays on the screen can be controlled through the 3D Grid tab of the Display Options dialog. This dialog is opened by right clicking on the File:3DGridFolder.GIF 3D Grid Data entry in the Project Explorer and selecting the Display Options command. It can also be accessed from the from the Display menu or the File:Dispopts.gif Display Options macro. The following table describes the display options available for the 3D Grid module.
Display Option | Description |
---|---|
Nodes | The Nodes item is used to display grid nodes depending on the Grid Type . If the grid is cell-centered, a dot is displayed at the cell centers. If the grid is mesh-centered, a dot is displayed on the cell corners. |
Cell edges | The Cell edges item is used to display the edges of grid cells. The cells are either drawn using the default cell color or the color of the material associated with each cell.
In addition to turning the display of cells on or off, you can temporarily hide grid cells. The color of the cell edges can be adjusted according to the following options:
|
Cell faces | The Cell faces item causes the faces of the grid cells to be drawn as filled polygons. |
Inactive cells | The Inactive cells item is used to display cells which are inactive. If this option is turned off, inactive cells are not displayed. Inactive cells must be displayed before they can be selected. |
Named layer ranges legend | A legend showing the material and named layer ranges can be turned on. |
Cell numbers | The Cell Numbers item is used to display the ID of each grid cell. |
Node numbers | The Node Numbers item is used to display the ID of each grid node. |
Scalar values | The Scalar Values item is used to display the scalar values of the active dataset for each node next to the node. |
IJK indices | The IJK indices item is used to display the ijk indices of each cell or node. |
IJK triad | The IJK triad item is used to display a symbol at one of the corners of the grid showing the orientation of the ijk axes. |
True layer display | With MODFLOW models, a special option called the True Layer mode is available. If this mode is selected, the user provides a set of top and bottom elevation arrays for each layer. These arrays can be used to display the vertical variations in the stratigraphy when in one of the side views in orthogonal viewing mode or when in oblique view in general mode. |
Layer borders | The Grid boundary item is used to display a solid line around the perimeter of the grid layers. |
Grid shell | The Grid shell item is used to display a solid cube around the extents of the grid. Displaying the boundary is useful when iso-surfaces are being displayed with the cell edges turned off. |
Texture map image | The Texture Map Image Item is used to "drape" an image over the surface of the 3D Grid. |
Contours | Most of the objects supported by GMS can be contoured by turning on the Contour Options in the Display Options dialog. When an object is contoured, the values associated with the active data set for the object are used to generate the contours. |
Specified Data Set | Allows the user to display the contours of a second data set that is specified by the user. All contouring options are the same for both the specified and active data sets. |
Vectors | If the Vectors item in the Display Options dialog is selected for an object (TIN, Grid, or Mesh), vector plots can be generated using the active vector data set for the object. One vector is placed at each node, cell, or vertex. |
Iso-surfaces | If the Iso-Surfaces item in the Display Options dialog is selected for an object (3D Grid or 3D Mesh), iso-surfaces will be generated. An iso-surface is the 3D equivalent of a contour line. While a contour line is a line of constant value extracted from a surface, an iso-surface is a surface of constant value extracted from a 3D data set. |
