Orbit Program is a handy, Java based application designed to display the dynamics of multiple massive objects interacting gravitationally.
The default scenario shows the figure-eight orbit of three particles first discovered by Montgomery. Additional particles and their initial positions and velocities can be specified using the Display | Switch GUI menu item.

Orbit Program has two main user interface components:
the Orbit Main window containing the orbit display;
a Guide window containing the position and velocity plotting sub-window.
The Orbit main window has 5 tabs, each representing a different family of orbits. The first tab represents the familiar figure-eight orbit of three particles. The second tab represents three-body orbits with two very large mass primaries and a small mass secondary. The third tab represents an infinite series of patterns of particles, depending on the initial position and velocity of each. The fourth tab represents a three-body orbit of arbitrarily changing masses. The fifth tab represents the three-body orbits of two masses fixed at different distances from a third mass.
The orbits may be time-dilated in order to provide more time-resolution. In this way, orbits can be observed through many revolutions.
Initially, display of the orbits is in real time (which for the 3-body case is simply the motion of the small secondary on its orbital path). Once the user selects a table of initial positions and velocities, the initial positions and velocities are held fixed while the orbits are plotted in real time over many revolutions.
Orbit Program Overview:
The orbit design is driven by the orbit lattice: (“lattice”, plural, “lattices”, singular) is the set of position and velocity vectors in three-dimensional space at times separated by a given time-step size. The size of the lattice is determined by the maximal allowed time-step size, which may be scaled for time-dilated versions of the display.
Each orbit point on the lattice represents the position and velocity at the particular time-step corresponding to that point. This means that a constant velocity vector can be expressed as many orbit points corresponding to different time-steps. For instance, a vector of 0.75c is mapped to orbit points 2, 3, and 4 in the three-body case, or to orbits 1, 5, and 6 in the five-body case.
Orbit Program Gallery:
The Orbit Main window contains a gallery of larger examples showing each family of orbits in detail.
Currently these are listed in the orbit gallery:

The default orbit. The red, blue, and green points denote particles 1, 2, and 3 respectively. Orbit Program is run from a Command Prompt window using the
Orbit Program Crack + Keygen
The Orbit Program has three possible UI modes, which can be selected from the upper right corner button of the window:
Orbit Mode – displays the orbit of a single large mass as a closed loop.
Moving Mode – displays the orbit of a single large mass but only shows the individual orbits of the particles that are currently moving.
Orbit and Moving Mode – displays the orbit of multiple particles, but only shows the individual orbits of the particles that are currently moving.
Please note, however, that moving and moving modes use the same orbit data, meaning that if you change something in Moving Mode, it will be reflected in Orbit and Moving Mode.
Click the button on the right, and then select Display from the next menu.
In the Display window that opens, set either the orbit type, the mass and the velocity of the single mass, or the masses and the velocities of all particles.
If you are making multiple runs to see the same setting values, ensure that the same mass, velocities and orbit types are selected each time. In most cases, the results will be consistent with each successive run.
You may also want to verify that your mass units are correct – Orbit Program is only able to show the proper quantities.
The cursor is shown in the center of the window, and the position, velocity and acceleration are shown on a graph.
All results are shown as vectors in a rectangular window.
For each vector the angle is shown, and the time is shown in the graph.
In certain cases, these values are shown in a circle.
Double-click on any data point to save the data as a *.txt file to your hard drive.
(This is only possible for the Moving Mode display).
To exit from any GUI, press Ctrl-F2.
Optional: You can select the numbers of particles to be displayed in the window by setting the upper bounds of the particle numbers graph in the Display window.
Orbit Program was written in Java and uses OpenGL for its display.
If you have an nVidia graphics card in your system, you can use Orbit Program with the ARB_OpenGL_Nothings Extension to improve performance and increase the quality of the rendered image.
You can download the latest stable version of this extension
NVIDIA OpenGL Extension Viewer 2.0.8
Supports the masses of N particles ranging from up to 1000 or more.
Weights can be specified for each mass to alter gravity, since the strength of gravitational interaction depends on the product of the masses.
Continued position of the particles in time is available as an interactive plot for each.
We can specify locations at a desired time in the past, or a time in the future.
We can specify initial velocity and position parameters in all three dimensions.
A JavaDialog with a menu based GUI provides access to various parameters, and allows various inputs to the program via the JTextFields.
The program can also be run with a setup file using Applet Viewer.
Orbit Program Setup File
Each time Orbit Program is run, it looks for and finds an Orbit Program Setup File. At each run, a new orbital history/experiment/simulation file is created. The setup file is then removed from the present location.
Launching and running Orbit Program
1. Launch Orbit Program.
By default, this is done by using the AppletViewer command, javaws.
2. Open Orbit Program Setup File.
If one is present, it will be opened in the JFileChooser.
3. Select Simulation Details.
To do so, click on the Display Switch GUI menu item.
In the Display Switch GUI window:
– Top menu – select the Simulation Details menu item
– Second menu – select the Display Switch tab
– Third menu – select the “Display Switch GUI” checkbox
4. Click on the Run Simulation button.
Orbit Program Output
At the end of a run of Orbit Program, the following output is produced (and stored in an Orbit Program Output directory as a file called simout102904.out).
1. Display Switch control GUI.
2. Orbit Program Summary.
This is a table listing all masses, initial positions and velocities, and a short description of the run.
If more than one planet is being simulated, then a checkbox is provided for each planet.
3. Orbit Program Output.
This is a plain text file listing the runs for all simulations.
In the output, each run is identified as Run
What’s New in the Orbit Program?
The Orbit Program is a Java based application designed to visualize the
dynamics of one or more massive bodies orbiting each other.
However, in contrast to all other popular dynamics packages,
the orbital dynamics for the various bodies are computed here using
Cluster Dynamics Formulation, a cellular-automata based model.
Unlike the known N-body codes, the model is based on a 3D Voronoi
tessellation, where a Voronoi diagram of the mass distribution is
mapped to a 3D lattice.
These lattices are treated as particles by the model and their motion is
determined by the local forces between them.
One of the advantages of the model is the ability to simulate a
system of a large number of interacting bodies with just a few
parameters, which means that it is possible to simulate
rather complex situations with almost minimal CPU consumption.

• The ability to set up simulations to be run multiple times without
having to restart the program.
