You can walk over a surface in Surfer's 3D view by following the steps below:
- In a 2D plot window, create a map with 3D data (e.g. a grid-based map, a post or base map).
- Select the Map in the Contents window and click Map Tools | View | 3D View.
- Click 3D View | View | Walk.
- Move your mouse cursor over the 3D view window. A directional arrow cursor indicates that you are in Walk mode.
- Scrolling the mouse wheel will move the view up and down in the vertical direction.
- Click and hold the mouse wheel and drag to pan the view up and down in the vertical direction.
- Click and hold the left mouse button and drag to begin walking.
- Dragging the mouse up and down will move the camera forwards and backwards along the surface in the view, respectively.
- Dragging the mouse left and right will pan the camera to the left and right in the view.
- Press ESC or another tool in the ribbon to exit Walk mode.
If you want to view the perspective from an exact value above the surface, follow the steps below:
- In the 3D View Contents window, click on Environment.
- In the Properties window, click the Camera tab.
- Expand the Position header, if necessary.
- Enter the elevation you want as the Z Position (in elevation units). For example, if you want the camera to be at 800 meters, enter 800 for the Z Position field.
Entering a value in the Z position field will set the height perspective to an exact value
Note: this also applies to Trackball mode. If you want to view the surface from an exact location or height, simply enter the X, Y and Z coordinates of the position you want the camera to be in, for the camera's Position.
