Add a Relief Surface / Create a 3D View from a Grid
In the 3D Viewer, you can use a grid file to represent the surface of a plane in a 3D View. From the Add to 3D menu, click on the Relief Surface option (V3DIMG GX) to open the 3D Surface from a Grid dialog and create a 3D relief surface.
The surface will display in the 3D Viewer window of the current View. The extents and coordinate system of the 3D View will be automatically set by the relief surface dataset added. When you close the 3D Viewer, the saved 3D View will remain added to the Project Explorer list.
The 3D View can be plotted to a new or existing map through one of these options:
- Drag-and-drop the 3D View from the Project Explorer list
- Drag-and-drop the *.geosoft_3dv file from Windows Explorer
3D Surface from a Grid dialog options
Surface relief grid |
If you would like the drawing plane to have relief, specify the name of a grid file that defines the surface relief. Note that if you do specify a relief grid for the plane, all objects drawn on the plane will only appear where the relief grid has data (non-dummy). Script Parameter: V3DIMG.GRID |
Colour image/grid |
Specify the name of a grid or image file that will be used to colour the surface of the relief grid. If a name is not specified, the surface relief grid will be used and the colour surface will coincide with the relief surface. Script Parameter: V3DIMG.IMAGE |
Colour method |
Select the colour method as one of the following options: As last displayed, Default, Histogram equalization, Normal distribution, Linear, Log-linear.The method "As last displayed" will display each grid as it was displayed the last time the grid was viewed, and the colour tables will be ignored. Script Parameter: V3DIMG.ZONE |
Colour table |
Select the colour scheme for rendering the 3D view. If you mouse over the colour scheme entry, a tooltip will display the name of the colour table in its folder. To modify the selection, click on the colour entry and then navigate through the scheme categories. Script Parameter: V3DIMG.COLOR |
Contour interval |
The contour interval. Script Parameter: V3DIMG.CONTOUR |
Brightness |
Select the brightness of the image drawn on the surface. Script Parameter: V3DIMG.BRIGHT |
New or current map |
You may choose to place the 3D View on a new map or draw it centered on the current map. Script Parameter: V3DIMG.MAP (0:Current map, 1: New map) |
Relief Surface Grid dialog options
3D Controls (script mode only)
Viewing direction |
The viewing direction in degrees azimuth relative to the coordinate Y axis. Script Parameter: V3D.DEC |
Viewing inclination |
The viewing inclination in degrees relative to the coordinate X-Y plane. Script Parameter: V3D.INC |
Viewing distance |
The distance of the point of view from the center of the view relative to the size of the view. Script Parameter: V3D.DISTANCE |
Draw bounding box |
Yes to draw a bounding box frame around the limits of the 3D View. Script Parameter: V3D.BOX |
Draw axis |
Yes to draw an axis with labels on the X, Y and Z axis. Script Parameter: V3D.AXIS |
X title |
Titles for the X, Y and Z axis. Script Parameter: |
