Loading and Manipulating a 3D Object

Parent Previous Next

To load an object you can proceed the same way as when loading a configuration. Find and load a file in your database directory which is not a TerrainView™ configuration.

The “Import” Dialog will appear, where you can define how the object(s) should be loaded:



Make sure that the “Object is terrain” and “Replace current scene” check boxes are deactivated and the “Explore mode” checkbox is activated. As soon as the object is loaded it will be placed in front of the camera at such a distance as to make it entirely visible.





After having loaded the object, TerrainView™ switches to the explore mode. In this mode, using the mouse will make the camera orbit around the object, always keeping it in the center of the view. That way, the object can be inspected from all sides. To switch back to view mode simply press the appropriate radio button in the “Navigation” panel below the 3D view .

Note that after the object has been loaded a small window containing a coordinate system appears in the lower left corner of the 3D view window. This denotes that TerrainView™ is in the so-called modify mode, in which you can manipulate objects. Furthermore, the newly loaded object is surrounded by a wireframe box, the so-called bounding box, which has three colored arrows emanating form its center. These arrows represent the local coordinate system of the object.

You can translate, rotate or scale the object as follows:


If at any time the bounding box disappears, this means that you have missed the object when clicking. Simply click on the object again, and the bounding box will reappear.

Note that as soon as the Shift and/or Ctrl keys are pressed, the mouse cursor changes into an icon illustrating the manipulation mode.

Here is an overview for the manipulation modes:

Mode

Keys

Cursor

Effect

Translate horizontal

Shift + drag with left mouse button

The object is moved along with the mouse pointer horizontally, the altitude of the object remains unaltered.

Translate vertical

Shift + drag with right mouse button

The object is moved vertically, only changing the altitude of the object.

Rotate X-axis

Ctrl + drag with left mouse button

The object is rotated around the local x-axis (indicated with a red arrow)

Rotate Y-axis

Ctrl + drag with right mouse button

The object is rotated around the local y-axis (indicated with a green arrow)

Rotate Z-axis

Ctrl + drag with middle mouse button

The object is rotated around the local z-axis (indicated with a blue arrow)

Uniform scale

Ctrl + Shift + drag with left mouse button

The object is scaled uniformly along all three local axes.


Move around the scene and populate it with various objects you will see that each object you have loaded is listed in the scene view, the tree control in TerrainView™s upper right corner. You can right-click any of these entries and select the “Jump to” item. This will instantly bring you to the selected object.
