Starting Location and World Origin
Look at the world origin represented by the red, green, and blue axes. The origin is near the lower left corner of the scene model:

RGB equals XYZ coordinates in Inspector and Vizard's coordinate system. Understanding the coordinate system is helpful for moving and placing models in the scene:

- Direction of red line is +X
- Direction of green line is +Y
- Direction of blue line is +Z
In a Vizard application the position of the camera (also called the viewpoint) is directly above the origin by default. For the purpose of Vizard it usually makes sense to place the part of the scene model where the user will begin their VR simulation at this origin.

In this scenario, the user should be start off in front of the house. To make this happen either the model needs to be moved in SU and then exported again or the model should be moved in Inspector.

Below are instructions of one way of doing this in Inspector:
Below are instructions of one way of doing this in Inspector:
- To move the scene in Inspector first determine where you want the user to be. Do that by navigating within the model to the location.
- Next check the camera position as shown in the status bar at the bottom. Here it's about [19,1.8,1]
- In the scene graph, double click on the top level node with the gear icon called 'house'
- Activate translate mode and make sure the transform mode is set to Global
- Either use the transform gizmo in the viewer to move the house or enter the negation of the camera values in the type in boxes above the viewer. The Y value can be left at 0:
- Click anywhere in the scene to deselect the house node and verify the origin axes is at the desired location
