When in walk mode in Surfer's 3D View, you can use the mouse wheel to increase/decrease the height above the surface. You can also hold the mouse wheel or center button down and drag the mouse forward/backwards to move up or down.
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.
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.
