Chapter 17. Interface
The JetStream interface is fairly simple. Most features are accessible from the control bars, which can be
turned on or off from either the View, Control Bars menu, or by right clicking on any of the displayed
toolbars. All the control bars are dockable and a useful hint is to hold down the Control key when moving
a dialog if you do not want the dialog to dock. It is also a good idea to right click on dialogs to discover
features that are not at first glance obvious.
JetStream has the concept of what unit the scene is presented in. This is most useful when measuring
items, setting tolerances for clash detection, or sizes of textures. There is a single scene unit that is set
from Tools, Global Options, Display Units and this unit is used throughout the interface whenever
appropriate.
You can also set a profile to determine how complex the interface is and which parts are available to the
user. See Section 17.11, “ Profiles ” for more information on this feature.
In the lower right hand corner of the interface there are four performance indicators, that give you
constant feedback as to how JetStream is performing on your machine.
• The progress bar under the left hand icon (pencil) indicates how much of the current view is drawn, i.e.
how much drop-out there is in the current viewpoint. When the progress bar is at 100%, the scene is
completely drawn, with no drop-out. The icon will change color when it is working. Whilst the scene is
being drawn, the pencil will change to yellow. If there is too much data to handle and your machine
cannot process this quickly enough for JetStream, then the pencil will change to red, indicating a
bottleneck.
• The progress bar under the central icon (disk) indicates how much of the current model is loaded from
disk, i.e. how much is loaded into memory. When the progress bar is at 100%, the entire model,
including geometry and property information, is loaded into memory. The icon will change color when
it is working. Whilst data is being read, the disk will change to yellow. If there is too much data to
handle and your machine cannot process this quickly enough for JetStream, then the disk will change
to red, indicating a bottleneck.
• The progress bar under the right hand icon (web server) indicates how much of the current model is
downloaded, i.e. how much has been downloaded from a web server. When the progress bar is at 100
%, the entire model has been downloaded. The icon will change color when it is working. Whilst data
is being downloaded, the web server will change to yellow. If there is too much data to handle and
your machine cannot process this quickly enough for JetStream, then the web server will change to
red, indicating a bottleneck.
• The field to the right of the icons reports the amount of memory currently being used by JetStream.
This is reported in Megabytes (MB).
The view menu gives you control over the JetStream interface. It allows you to hide or reveal control bars,
customize the toolbars and status display, and split the current view into several smaller views. It also
allows you to display statistics about the currently loaded scene.
