What it Does

This dialog is used to modify application preferences.

General Description

Preferences are used across all projects created by Qimera.  They are not project specific.  There are 3 preference tabs which are described below.

General Preferences

Processing Options

The Processing group has two configurable options. The first option allows you to configure Qimera to use data from backup sensors in the event that the primary sensor is either missing data or a time span of data has been edited in the Time-Series Editor using the Invalidate Edit mode.  If backup data is of reasonable quality, it is preferable to enable this option.  If backup data is of poor quality, or incorrect, it is advised to disable this option.

The second option allows you to change the ping buffer memory size during sound velocity correction.  During sound velocity correction, Qimera will buffer the processed pings into memory and write them at all at once.  The size of this buffer determines how many are stored before writes to disk.  The large this buffer, the more efficient your processing will be.

Scene Mouse Behavior

Some user workflows prefer scene navigation by default for any mouse interaction.  Some user workflows prefer the original behavior.  You can change the mouse navigation behavior of Qimera by changing this option.  

The Selected Mode behavior allows mouse interaction with the scene to perform the operations allowed by the selected mode.  For example, in Area Select mode, if you left-click-drag over a surface in the scene, you will create a selection area.  Doing this in another location will create a new selection area.  If you want to navigate within the scene, you have to hold down the SHIFT key.

The Navigate by Default option will navigate the scene with any mouse interaction for any selected mode.  In order to use the capabilities of the selected mode, you must hold down the SHIFT key.  For example, if you are in Area Select mode, you must hold down the SHIFT key to select a new area.  

Scene Options

The Background Color and Foreground Color options allows you to change the colors of the 4D Scene.  Simply click on the button go get the color picker dialog show below.  Use the Swap button to swap the foreground and background color.

The Dynamic Surface Shading group options allow you to change the shading mode of the Dynamic Surface.  The major difference is how the shadows are represented.  For Fast Shading, the shadows are show through a standard hill shading algorithm.  This is all done by the video hardware and requires no additional processing.  The Mixed Shading option will show Fledermaus cast shadows using the Fledermaus shading engine.  While superior to hill shading, there is additional processing required to generate the additional illumination parameters.  The effect being when you first create a surface or switch surfaces, Qimera will start a process to generate the illumination parameters.  During this process, you are switch back to Fast Shading mode until the process completes and the cast shadows are show.  The larger the surface, the bigger the processing penalty to generate.

Slice and 3D Editor Options

Use Surface Edit Overview

By default, the Surface Edit Overview loads the Dynamic Surface and Visited/Edited areas overlay whenever you use the 2D Slice or 3D Edtior.  You can turn this behavior off using this checkbox.  This can help improve performance if you are editing a very large surface on a laptop that should have been retired in 2005.

Plotting Options

You can change the background color of all plot based widgets to either black or white.  When you switch colors, the grid line color will also invert so that the lines are visible.  This includes the Time Series Widget, Multiplot Widget, Swath Editor Widget, Slice Editor Widget, SVP Editor Widget, Patch Test Widget, and Wobble Test Widget.

Middle Mouse Button Centers

By default, clicking the middle mouse button in a plotting surface will re-center the plot to that location.  You can disable this feature using this preference.  

Remembered Prompts

Part of Qimera's Dynamic Workflow is to prompt the user with questions about the next logical step in the process.   For example, after you create a project, Qimera will show you the following prompt.

If you click the Add Raw Sonar Files option, Qimera will launch the Add Raw Sonar Files dialog.  If this is your preferred action, simply check the Don't ask again option and Qimera will always perform this action when you create a new project.  It will also remember if you select any of the other options and have the check box selected.  The answer will then appear in the Remembered Prompts table as show below.

In addition to the prompt bar, many message boxes with Qimera also have Don't ask again or Don't show this message again check boxes. These work the exact same way and are also shown in the Remembered Prompts table.

If you want to change you answer and bring back the prompt, simply select the row and click Forget Selected. Click Forget All to bring back all prompts.

ENC Preferences

Chart Data Folder

This path dictates where Qimera will look for QNC files to load for chart display. Change this only if you want to use QNC files from outside the default hierarchy.

On Windows, this preference is shared with the ENC Administrator. Changing it in one application will update the other.

Chart Presentation

The Color Palette option can be Day, Dusk, Night

The View Class option can be Base, Standard or All.  This determines the amount of background data in the chart such as buoys and sector lights.

The Presentation Mode option effects how various features are symbolized. Traditional, Simplified and Modern symbol sets are available.

The ENC Usage option controls how Qimera transitions between charts in the same area as the view scale changes. "Standard" employs the usages levels standardized by the IHO. "Use Compilation Scale" employs the usages specified by the maker of the chart.

The Use SCAMIN option displays objects only when the scale is smaller than the minimum scale set for that specific object. This prevents cluttering of the screen when zooming out.

The Show Shallow Pattern option displays a pattern to indicate a shallow area.

The Show Symbolized Area Boundaries option enables the display of boundaries around areas.

Chart Depth

The Show Shallow Sounding option shows actual depth numbers.

The Show Deep Sounding option shows actual depth numbers.

The Show Two Shaded Depth Areas option shows shallow and deep water separated by the safety contour, which is a thick gray line.  The default is four shades of blue: dark blue for shallow water to light blue for deep water.

The Show Contours option shows lines connected places of the same depth.

The Shallow Contour option shows a line around a shallow area. Set the depth value for this contour. Only enter when Show Depth Contours is activated.

The Deep Contour option shows a line around a deep area. Set the depth value for this contour. Only enter when Show Depth Contours is activated.

Chart Information

The Show Information Points option will show an information symbol with an object which has additional information available.

The Show Light Characteristics option shows the light features of buoys and sector lights.

Shared Preferences

Startup Options

The Interface Language combo box allows you to select the language to be used by the user experience when Qimera is restarted.  This list will increase over time and new language packs will be available from the download section of Qimera.  

Display Options

These options change how geographic or projected coordinates are viewed in dialogs and the Status Bar of Qimera. 

Geographic Options

Projected Options

Default Surface Shading Options

Please see the sections on the Shading and Colormap dialog for more information on this section.  These options are used whenever creating Dynamic or Static surfaces in Qimera.

System Options

The Default Project Folder allows you to specify a folder where that applications will prefer when opening existing and creating new projects. This is a convenience only; projects can still be opened or created elsewhere on your system.

The User Plugin Path allows you to specify a directory from which application plugins will be loaded (in addition to the system plugin directory). This only applies in scenarios where there is a need to load plugins other than those installed with Fledermaus.

The Maximum Processing Threads dropdown limits the number of tasks the applications will attempt to run in parallel. Setting it too high may reduce system responsiveness, while setting it too low may fail to make efficient use of processing capabilities. It should generally be left at "Automatic".

The ArcGIS License Checkout dropdown allows you to specify which, if any, ArcGIS license type you would like to checkout to when using ArcGIS integration features. "Automatically Determine License Type" is the default for convenience purposes, but can be slower than choosing a specific license type, especially when checking out licenses over a network. Note that this setting is only available on ArcGIS capable licensed copies of Fledermaus.

The Caris License Path allows you to point at a specific Caris license file to be used with Caris related features.
