2)Define the Widget properties. You can set the Widget title and create sections for the Widget by selecting the Create Section button.

3)Define the section properties by setting the Section Title and adding entries for the section using the Add Entry button.

4)For each entry, the Entry Properties are defined. There are four types of entries available: Mission Plan, HTML Link, Executable, and File. From here, you can configure the Display Text and the properties for each type of entry which are listed below.

Mission Plan: Specify the file location and choose whether to open or run the Mission Plan when it is clicked

HTML Link: Specify the web address of the page to open

Executable: Specify the executable location and any arguments for that execution

Display


The display preferences are divided into separate pages as follows.

 

Editors

From this page you can change the settings of the FreeForm Script Editors. There are five sections:

           

1)Display: Set options on how text is displayed in FreeForm Editors including bracket highlighting, displaying line numbers, wrapping words and others.

2)Area Colors: Configure the background colors for the line numbers, margins, and text area.

3)Line Modification Colors: Choose to turn on modification coloring, and highlight unsaved text in a different color.

4)Autocomplete Logic: Choose whether to enable Autocomplete when typing in FreeForm Script Editors. You can also choose whether pressing the spacebar will commit to a selection in the Autocomplete menu. See the Syntax and the FreeForm Script Editor article for a discussion of Autocomplete Logic.

5)Syntax Colors / Formatting: Configure various formatting options for each type of script syntax: Blocks, Commands, Comments, Functions, Keywords, Line Numbers, Numbers, Object Methods, Object Instances, Object Properties, Object Types, Operators, Plain Text, and String Values. For each item, a font, size, style, color, and background color can be set. A preview window is shown in the lower right section of the screen.

Mission View

On this configuration page, you have control over various display options for FreeFlyer's 2D and 3D output windows. See the Generating Output Guide for information on creating Mission Views.

Rendering Options: Set preferences for Rendering Mode, Anti Aliasing, Anisotropic Filtering, and Lock to Refresh Rate

oRendering Mode: Select whether to use the system's Default Renderer or to Force Software Rendering

Use Default Renderer: Output Window graphics will be rendered using the system default graphics rendering device (Intel GPU, NVIDIA GPU, etc...)

Force Software Rendering: Output Window graphics will be rendered entirely in the CPU. Software rendering will typically result in slower performance for output visualizations

oAntiAliasing: Smooths over jagged distortions to improve visualization quality. FreeFlyer employs Multisample AntiAliasing (MSAA). The AntiAliasing multiplier refers to how many samples are taken around alias artifacts to assist in smoothing. Higher multiplier indicates higher visual quality at the expense of performance.

oAnisotropic Filtering: Improves the clarity and crispness of textured objects. The multiplier levels reflect the viewing angles at which anisotropic filtering is applied, where higher multipliers will filter more textures at slight expense of performance.

oLock to Refresh Rate: Selecting this option will increase the smoothness of graphical updates by locking the rendering rate to the screen refresh rate at the expense of performance speed.

Celestial Bodies: Set preferences for each Celestial Body

oSpecify image files for textures

oFor the Earth: Specify image files for day and night, specular map, clouds, and bump map. Set render quality using the slider. A message will show whether or not the Earth will be rendered in a very high, high, or low quality based on the combination of texture files and render quality selected.

 

Note: MSAA is a technique where you take more than one color sample per pixel to get a better approximation of what color the pixel should be on the edges. The more samples, the better quality the approximation. While the drop down list of available Anti-Aliasing options varies by graphics driver and includes multipliers and letters (indicating techniques), the drop down list is ordered by increasing quality (and decreasing performance) in all cases.

 

Note: The bump map in FreeFlyer represents the surface normal in tangent space, not the actual height. A bump (or normal) map contains the surface normal encoded into the RGB channels for XYZ respectively. A height map contains a single value per pixel representing the relative height above sea level. There are several online tools available that can help you convert a height map into a bump map, or you can generate your own by finding the gradient in the height for each pixel and turning that into a normal.

Plot

On this page, you can configure maximum number of points to plot before data is culled, the number of points that are accumulated before the plot is updated, and whether or not to show the "Display data is culled!" message on Plots.

Output Workspaces

With these options, you can define the behavior of output workspaces when running a Mission Plan multiple times. The "Multiple" workspace mode creates a new workspace for each run, and the "Selected" mode generates new output in the selected workspace. You can also configure the maximum number of workspaces allowed, and whether to close all workspaces when a Mission Plan is run.

 

Controls

With these options, you can select whether to show the throttle bar (unselected by default); if shown, the throttle bar can be used to control the speed at which a Mission Plan runs. You can also select whether replay and movie generation capabilities are enabled (selected by default) and configure slider behavior for the replay toolbar. The "Max. Storage Per Instance" field sets the maximum amount of disk space available to the replay/movie generation functionality; if the maximum disk space is reached, then older frames will be dropped as necessary from the replay-able output or generated movie.

 

The Controls page of User Preferences

Note: If 20% of the maximum storage space is not available, then replay and movie generation will automatically be disabled.

 

 

Mission Plan Defaults


The Mission Plan Defaults section controls the options used by default for all Mission Plans. These defaults can be overridden for individual Mission Plans through the Active Mission Plan Preferences editor.

 

Timing Precision

This page specifies the default timing precision mode for FreeFlyer Mission Plans when you use the Ctrl+N shortcut on the home screen or when you press the New Mission Plan icon on the menu at the top of the screen.

 

Data Files

On this page, you can choose the data files used for new Mission Plans. By default, files included with the FreeFlyer installation will be used, but these can be overridden with custom files by unchecking the "Use System Default" button and browsing to the desired file. See the Data Files reference for more information on the various files and their formats.

 

Description

Here, you can configure descriptive information for the Author, Source, and Revision Number for your Mission Plans, as well as a Title, Subject, and Category, and any Keywords, Comments, or Notes.
