Just get on the File dropdown menu and select Open. A file menu dialog should
popup now. MinkRelVis can load several major 3d file formats:
- 3d Studio (.3ds)
- Data Format Exchange (.dxf)
- Alias Wavefront (.obj)
- LightWave Scene files (.lws)
- VRML2.0 or VRML97 (.wrl)
- Caligari Truespace (.cob)
- Imagine Object file (.iob)
Be careful with VRML files not all nodes are supported in the current loading routines.
The program might crash. You can of course use one of the example 3d files coming
with MinkRelVis.

After choosing the file you want to load MinkRelVis will popup a dialog which will
ask some questions what he should do. You can tell him to import camera and light
data (camera works for .lws, .obj and .wrl). Or if he should scale the objects
of the scene that they all fit on the current viewport (Scale to fit on screen)
and if he should set the corresponding back clipping plane to the boundary of the
scene. Note that fit on screen and import camera data exclude each other. Also
we don't recommend to import light data as it doesn't seem to work correct with
any format supported.

|
Next you might want to add a new intersection plane or observer into
the system. Just get to the Edit dropdown menue and select new plane
or new observer.
|
|
You can switch between the different navigation parts by clicking on one of these
Buttons. The first one is for your normal scene view viewer, the second one is
for changing the plane, the third one is for changing the observer.
|
|
By pressing with the right mouse button on the red market rotation icon
a popup dialog will appear where you can enter the rotation parameters
for this rotation transformation numerically.
|
|
You can change the velocity of the relativistic observer after creating
by pulling this red market slider. All three viewports will be updated
automatically.
|
|
To activate the light cone(s) in the Minkowski Diagram you just have
to get to the Edit dropdown menue of the Minkowski Diagram viewport
and select "Show observer light cone"
