3. Getting Started
You may save your current work at any time by using the Save or Save as option in the File
menu. As an example, use the Save as option and name the scene jaw1 (the original file will
then not be overwritten). The file extension .vgi (Volume Graphics Info file) will be added
automatically and therefore has not to be added by you. To reload the current scene, you may use
the Open option in the File menu.
A single image such as the rendered 3D image or one of the slice images may be saved by selecting the appropriate image window and using the Save image option in the File menu.

Scenes, Scene- & Object-Coordinate-System and Units
All objects loaded into VGStudio MAX will be placed into “the Scene”. The scene is the virtual
space displayed in VGStudio MAX’ 3D window. By default, the orientation of the scene coordinate axes will be oriented as shown in the following figure.
Fig. 31 The VGStudio MAX scene coordinate system.
The coordinate system used by VGStudio MAX is right-handed, with the coordinate origin in the
lower left corner. The coordinate origin is on the left side of a body (x), at the front (y), and at
the feet (z). By default, the positive x-direction in the scene runs from left to right. The positive
y-direction in the scene runs from the front to the back of the screen plane. The positive zdirection in the scene runs from the bottom upwards. However, these orientations represent the
default settings. The whole scene may be rotated or moved with help of the World view tool. All
axes or planes orthogonal to the axes in VGStudio MAX have a consistent color coding. The xaxis and planes orthogonal to the x-axis are displayed in red, the y-axis and planes orthogonal to
the y-axis in green, and the z-axis and planes orthogonal to the z-axis in blue. For easy identification, all sections in the windows of the tool box related to the coordinate axes are also marked
according to this color scheme.
