extended GroundLocation from celestial bodies to spacecraft and changed the name to Location to reflect new capability. Now a Location can be added to any celestial body or spacecraft and used to detect line-of-sight with other spacecraft or locations.
added setting to the Save Message panel (under File) to opt in to saving a copy of all messages to a file on Vizard exit
added command line argument -saveMsgFile to allow user to opt in to saving message file during launch of Vizard
changed how opNav stores its received messages: unless the -saveMsgFile argument is used on launch, the message dictionary will retain only the most recent 20 messages. This was done to prevent unnecessary memory usage by Vizard during long opNav runs.
brought Phobos and Deimos prefabs to current standard Celestial Body prefab configuration.
Add was changed to Edit for the three items under the View menu
Added a script for protection for 2 finger scrolling to all scroll bars in the Viz: If the mouse cursor is over a scroll window, the zoom function of the main camera is disabled
added a new
View/Display VizMessageLogoption which brings up a panel to see the raw protobuffer messages being displayed.
added a protobuffer setting and a GUI setting to allow users to set the Spacecraft scale size in Planet View or Solar System View.
changed the standard camera positioning in Planet View such that the cameras will be repositioned outside of the scaled up spacecraft mesh when the view changes from Spacecraft Local View
added Ground Location objects to Vizard:
Ground Locations can be created in the GUI under
View>Add Ground Location
Ground Locations can be scripted as a sub message of the VizMessage protobuffer message
Ground locations are drawn with a small sphere on their parent body
Field of view of ground locations can be visualized by showing the Field of View Cone. These cones can be toggled in the Ground Location panel.
If a spacecraft passes within the field of view of a Ground Location, a line indicating communication will be drawn between the Ground Location and Spacecraft. If another body (planet, moon, or spacecraft) occludes the spacecraft, the line will not be drawn. These lines can be toggled on the Ground Location panel and are on by default.
Added labels for Ground Locations, a toggle in the Labels panel, and a protobuffer setting show/hide the labels
organized the Settings panel into tabs to improve usability and future expansion
user can choose the chief spacecraft for the relative orbits to be other than the current main camera target under the View menu. This setting can also be scripted as a vizMessage setting
spacecraft shadows can be brightened using a setting in the General tab of the Settings panel. This setting can also be scripted as a vizMessage setting.
added the ability to save off all or a portion of the messages in the current run to a new file. This new function is available as “Save Messages to File” under the File menu. This feature works in both file playback mode and live-streaming mode. The data is safed into a sub-folder
VizardDatain the user’s home directory.
Heads Up Displays of Coarse Sun Sensor coverage and boresight vectors
Panel Display of Coarse Sun Sensors measurements
updates to the vizMessage.proto to support Coarse Sun Sensors messages and settings
Standard Camera Panel settings fields can now be hidden by clicking a button on the panel providing a more compact view
changed the Unity player setting for the resolution quality panel to “Hidden By Default” to hopefully prevent it from popping up on every Windows app launch
inertial origin coordinate frame that is visible when only spacecraft messages are present (no celestial body messages) can now be hidden by toggling off the All Planet/Moon CS under the View menu
spacecraft relative orbit lines can now be calculated using the chief spacecraft’s velocity frame instead of the Hill frame.
added Setting panel toggle and vizMessage setting field to allow user selection of relative orbit frame
added velocity frame coordinate system that can be toggled on under the View menu and a vizMessage setting field to show the axes
the settings fields on the Standard Camera panels can now be hidden by the user so that only the camera image portion of the panel remains visible
Added the ability to visualize the osculating relative trajectory with respect to a target spacecraft. This works for circular, elliptical and hyperbolic trajectories!
Added scripting options to support the relative trajectory settings
Make the instrument camera show other spacecraft within the field of view
Enhanced the look of the default bskSat CAD model
Added Hill Frame Coordinate Axes display that can be toggled on under the View Menu or through scripting
The vizMessage thruster default and individual color settings are supported. You can also change the default color setting in Settings panel and scale the length of the thruster plumes (make them half as long, double, etc.).
The thruster panel now properly labels the thruster groups
The size of the thrust plumes is scaled to maxThrust until the maxThrust value is equal to or less than 0.01N. All micro-thrusters below 0.01N in size are visualized as a very small thrust puff/plume.
This update also contains the ellipticity for all the celestial bodies we currently support.
Fixed a small bug in the Keep Out/In Cones. If you modified an existing cone and changed it’s type (from Out to In or In to Out) the coneViolation flag was not reset so you could end up seeing erroneous results until the state update was triggered. Now whenever an existing cone is modified that flag is reset.
keyboard camera rate controls now with hot-keys for zooming in and out (
]), pan left and right (
→), tilt up and down (
↓), roll left and right (
>). Pressing these keys multiple times increases or decreases the camera rate
sto stop all camera rates toggled with hot-keys
hot-key help panel (press
hto show or use button under view menu)
removed time display button under Time menu because we now use hot keys
switched to 3 quality levels for viz app (Fast, Good, and Beautiful) and confirmed that shadows are showing up in Beautiful even on the AVS model. The Beautiful mode requires a good graphics card to yield a good frame rate.
added flashlight to camera, still toggled by
L, useful to illuminate spacecraft when in shadow of a planet
fixed sun threshold bug that caused mesh not to show up from some angles
new timeline slider bar that live updates the rendered view
File/Settingsoption to bring up a settings panel to change system default values
very cool new ray-traced shadows. You need the medium or highest graphics setting to see these. It is even possible to cast shadows onto nearby spacecraft.
added option for playback of messages in real time. Real time mode references the system clock and advances messages as needed to keep pace with the current sim elapsed time of the message. Real time playback can be increased or decreased from 1x with the playback speed controls.
Real Time or Frame Rate playback options can be selected under the new Time menu
playback speed display modified to show the current playback speed relative to real time rather than the old frame rate speed
added a data rate display to allow user to see for how many Unity frames a vizMessage is displayed. Data rate display can be toggled under the Time menu or by pressing ‘d’ on the keyboard.
added epoch submessage to the vizMessage. If user omits epoch message, a default epoch of January 1, 2019 0h 0m 0s is used
epoch message is used to calculate Mission Time display which can be toggled on from Time menu or by pressing ’t’ on the keyboard
added vizMessage user setting to show mission time as 24 hr clock. This setting can also be toggled from the Time menu.
added vizMessage user setting to show the data rate display
updated the playback control sprites and slider for a clean look
fixed a bug in the handling of custom model user settings where the Standard shader was not applied during custom model import when specified by user
identified issue in custom model import: obj importer will not correctly import materials that were given a numeric name (i.e. “1”) Current workaround is to rename materials in .mtl and .obj files to use non-numeric strings.
added 2D sprite representation of spacecraft and celestial bodies to support spacecraft constellation modeling and easier visualization of distant objects
added Sprite settings panel under view menu to allow customization of displayed sprites’ shape, size, and color
panel includes toggles to turn on/off sprite visualization for distant spacecraft or celestial bodies
added fields to protobuffer messages to allow setting of those toggles
added fields to protobuffer messages to allow user to specify a default spacecraft sprite as well as sprites for individual spacecraft
added code to disable HUD when their parent spacecraft is in sprite mode
other issues addressed in this release:
fixed bug in thruster HUD where thrusters with a minimum thrust of 0.5 N or less would not display a thruster plume by adding a floor to the particle life setting
changed the protobuffer message default value for boolean flags to use 0 for viz default, -1 for OFF and 1 for ON. This matches the default value of 0 sent in all protobuffer messages for int32 fields.
labels that belong to occluded bodies will now disappear until their body is visible again
added floating labels for the following:
sun, planets, moons names
thruster HUD components
reaction wheel HUD components
standard and instrument camera names
labels can be toggled on and off from Labels Panel accessed through the View menu
label font size can be increased or decreased through the Labels panel
labels can also be toggled by type by using newly added fields in the Protobuffers vizMessage

rebased on Unity2019.2.16f1
The camera view panel screen shot button now stores the PNG image in the user’s home folder
Changed how standard cameras work. The user can invoke readily 2 standard cameras and specify for which spacecraft these are attached. This scales much better with lots of spacecraft where before we attached 3 standard cameras to each spacecraft by default
made it possible to launch vizard in Black Lion live streaming mode from command line
Added option under File menu to compress simulation data
usability improvements to custom CAD model inventory and tuning GUI panels
added ability to load in a custom CAD obj file to replace the default spacecraft model
added the ability to replace any simulation object with a custom object or a default shape like sphere, cone, cylinder, etc.

scriptable vizMessage user settings allow users to customize the start-up configuration of vizard. Users can now toggle spacecraft and planet coordinate systems, orbit lines, actuator Heads Up Displays, actuator panels.
users can specify a custom skybox by providing a file path to the desired texture, one of the default skybox textures, or a plain black background with the skybox user setting
Spacecraft camera vizMessages can be configured to user specified headings or targets and panels can be automatically visible on start-up.
configuration messages specifying multiple pointing vectors and/or Keep Out or Keep In cones can be added to generate these items automatically during Vizard initialization
added a lightweight opNav mode that can livestream camera images to the Basilisk simulation over the Direct Comm connection on demand
improved main camera panning

Initial public release of the new Unity based Basilisk visualization tool.
This tool is able to illustrate spacecraft translational position, trajectory, orientation and primary celestial bodies.
Currently this public Vizard copy support saving Basilisk simulation data to file to be then viewed in Vizard.
In development feature is being able to live stream Basilisk simulation data to Vizard directly
The Visualization can show a spacecraft centric view (default), a planet centric view (enabled by double clicking on planet or zooming out even further), and a heliocentric view (by zoom out even further)
Spacecraft and planet axes can be toggled on or off
Screen size can by dynamically changed
The menu bar at the top is dynamic in that it only shows device options if such devices are actually modeled and sent as messages to Vizard.
Heads-up visualization of the thrusters is possible
Device state panels can be enables for Reaction Wheels or Thrusters
Separate camera views can be invoked to get perspectives from the spacecraft along particular body-fixed directions
Direction vectors can be added from the spacecraft to other object to always illustrate the heading to the sun, the Earth, etc.
Keep-out and keep-in zones can be set within Vizard to visualize if a celestial object is visible within a body-fixed cone. This enables checking if a solar panel axis is within some degrees of the sun, or checking that a sensor axis is outside a cone relative to the sun.
