EfeCalc - Cálculo de Efmérides Astronómicas no PC

Planetary Window

This window it's only available since the version 2.0 and it is the typical Planetary window.

There are many items in this window, and they are grouped by characteristics.

So, we have the observation window, and on the right side there are many buttons. These buttons are for close the window - Back, to capture an image and save it to the computer - Capture and also a lot of buttons to change the color of the Sun, Moon and Planets, and also de Grid and Background colors.

On the top of the window there are two rows of objects. In the first one you can find two calendars, the commands to control the simulation and also the coordinates of the mouse pointer (when available).

The second one is about the objects present in the simulation.

• Parameters for the Simulation

The user can choose between the static and dynamic mode, i.e., besides he can see where are the astros in the desired moment he can also watch a automatic simulation. To watch the simulation he must choose the interval and push the Play button.

• Type of the Graphic

There are many different types of graphics: Geocentric, Heliocentric, Plane of the Equator, North Pole and South Pole. For oblivious reason some objects cannot appear in some kind of graphics, for instance, the Earth cannot appear in a Geocentric observation...

• Full screen

Sometime it will be useful to do a presentation with the simulation of the movement of the planets, so the user cannot switch the application to Full screen. So, if the user right click on the observation window, the menu at right will appear, and if after that click on the Fullscreen, the monitor will be fill with the simulation. Besides the switch to Full screen the user can also use this menu to control the simulation and take a photo to the graphic.

But, if the graphic fill the screen, the buttons will disappear, so because of that reason, the user can use some keyboard shortcuts and the mouse right button.

Using the keyboard the user is able to:

[ESCAPE] Key - Toggle between Normal Mode / Fullscreen;

[+] or [-] Keys - Change the speed of the simulation;
