The Cosmos tableau is displayed by selecting "Tableau" | "Cosmos" from the main menu, or by clicking the "Cosmos" Toolbar button.
The tableau presents a 3D view of the Solar system as it would be seen from a point in space. Planets, their orbits, and background stars are visible. The view is authentic - objects are drawn to scale and in their correct position for the select moment in time.
When the tableau is first displayed (or redisplayed), it uses the current event-data date and time. This is updated if you use Dynamics of Time or Location operations in the tableau. However, if you select Motion for the tableau (see section below), this will not affect the event-data.
Pausing the mouse pointer over any object in the tableau (planet, star, asteroid) displays its name or designation in a popup info tooltip.
To orient the observer, at top-right the tableau has an X/Y/Z-axis vector for the system of rectangular ecliptical coordinates used in the tableau. At top-left is displayed the distance in Astronomical Units (au) from the central object of the tableau to the observer, and the rectangular ecliptical coordinates of the observer relative to this object.
To reposition the viewpoint click in the tableau and drag the mouse with the button held down, or use the four arrow buttons at the right of the Toolbar (keep pressed for continuous rotation). Vertical X-axis movement rotates the angle of sight, horizontal Z-axis movement relocates the viewpoint around the system.
You can also use the cursor (arrow) keys on the keyboard:
To approach or withdraw from the central object, click the "Approach (Home)" bullet button or the "Recede (End)" point button on the Toolbar,
or use the Home and End keys. You can obtain faster movement by pressing Ctrl+Home and Ctrl+End, or Alt+Home and Alt+End. For very slow movement use the Shift+Home and Shift+End key combinations.
The Approach/Recede facility differs from the telescopic Zoom In/Out option. The former simulates smooth actual movement thru real space, the latter is the equivalent of stepping the zoom level in a telescopic view of the object. These functions differ in the type of perspective they create.
To operate the telescopic Zoom function click the "Zoom In (PgUp)" bullet and "Zoom Out (PgDn)" point buttons located on the Toolbar,
or use the "Page Up" and "Page Down" keys.
Sometimes extremely slow movements are needed (e.g. to view eclipses). In this case set the "Speed of Movement" divider to a different factor:
Pull down the red bar to reduce the speed by a factor of 10, 100 or 1000.
You can increase and decrease the imaged brightness of stars using the "Star Brightness" buttons:
The Cosmos tableau can be animated (see Dynamics of Time).
Right-click the mouse for a popup menu. (Some menu options may be unavailable, depending on the object under the mouse pointer). TIP: to ensure menu options are correctly enabled for the object, wait until the tooltip name or designation is displayed before clicking.
The Jump option transitions (teleports!) the observer within the system to the chosen planet or star. After jumping, the selected object will be at the center of the tableau.
If you teleport too far from the Sun, you can get lost among the stars. If that happens use the "Return to Sun" menu option.
This option displays a window of astronomical data on a planet and star. The planet data window consists of two pages:
The first page displays current coordinates of the planet and times of events: rising, setting, upper and lower meridian transit (3 out of 4 of these points are always displayed, depending on the horizontal planet location).
The second page displays the planet's orbital parameters and distance from the Sun and Earth.
The star data window depends on the observer's location in the system. If it is in the Solar System, the 1st and 2nd of the pages below are used; if it is in a different star system, the 3rd page is shown:
The first page displays the current coordinates of the star and times of events: rising, setting, upper and lower meridian transit (3 out of 4 these points are always displayed, depending of star's horizontal location).
The second page displays some star parameters:
The third page displays other parameters:
The "Show..." option opens a new window containing an image of the selected object from an astronomical photo-album, if an appropriate file is available. The option has no effect if no graphics files are found. If there are several images for the object, you can select one from the submenu list.
You can display an object's name permanently on the tableau - point the mouse at an object (a tooltip with its name should appear), click the right mouse button and select this menu item. To delete the label, repeat the procedure.
On the Internet
This item is enabled if the mouse is pointed at an asteroid (the "All Asteroids" option in Cosmos Settings must also be enabled - see below). Selecting this menu item, e.g. for asteroid "Amber", displays the following window:
Select a URL link and click "OK" to connect to a Web site with a description of this asteroid (the name of the asteroid is inserted automatically).
You can modify the list of link templates, by editing the Asteroids\link.txt file.
This option opens the Satellites window, which contains data on the planets (as satellites of the Sun), or on the moons of planets (after Jumping to a planet):
The data includes:
Right-clicking the mouse in the Satellites data table displays a further popup menu:
Find...This option opens the Find Object window. See Searching for Objects.
The "Motion" menu item displays a dialog with the option of activating permanent motion of the Cosmos tableau:
Input the desired speed and click OK (the dialog will be closed).
To stop the animation press the Esc key or click the tableau with the mouse.
Display settings for the Cosmos tableau are available on its popup menu (right-click in the tableau). They are also available by selecting "Settings" from the main menu or clicking the "Settings" Toolbar button, then selecting the "Cosmos Settings" menu item.
With the Planet Surface Designer you can create simple (non photo-realistic) surface images for planets displayed as disks in the Cosmos tableau (if the Show surface image option is off). Planets have disks when you 'Jump' to them or when you approach them sufficiently closely.
A planet surface image is defined by a primary color for the surface and a set of pots.
A pot is defined by the following parameters:
The top two fields of the Surface Designer dialog contain the name of the planet (at left), and the names of files describing the object to the surface designer (at right).
To change the colors of a planet, area or contour pot, left-click in the Color panel across from the corresponding label.
Create button - effects the creation and addition of new pots with the specified parameters.
Change button - secures changes of parameters that define a staining tint or tone to be applied to areas of the object. (If the main color is changed, it is unnecessary to click this button as the color is automatically saved).
Delete button - naturally, deletes the current pot.
Multiply button - adds pots for 10 circular stains. The parameters of these are derived from the basic image and can be individually altered (excepting that the Radius setting cannot exceed the planet's radius).
Files containing planet surface descriptions are stored in the [ZET]\img\ folder, and have the names :
p2.img... p10.img, p2.nme... p10.nme.
Return to Sun
If the display is centered on a planet or star, selecting this menu option redraws the tableau with the Sun centrally in view.
