I would like to start a fun project to create a vb6 program to create a orbit simulator.
Is there anybody that's done this that could give me some tips?

enigma said:Unless you go with either an extremely small timeslice or only a few orbits, there is a chance that using the Euler method (described by marcus) will not give you a closed orbit. Errors in the timestep cause the orbits to fall outwards. You may need to implement a runge-kutta method for long duration simulations.

I guess I can start with the Sun & Earth.
Sorry for pulling up such an old thread, but I've only been a member of this facinating forum for about 2 weeks. But I did exactly what you described. I wrote an orbit simulator in VB 6.0.

Actually, the first order Euler method works remarkably well. With a timestep as large as 16767 seconds per time step, the solar system holds together for over a million years. Probably more, as I ended the simulation at 1 million years because it took my computer a month to do. I can speed this up to 65536 if I remove moons from the solar system. Faster than that causes Mercury to deviate from its orbit.enigma said:Unless you go with either an extremely small timeslice or only a few orbits, there is a chance that using the Euler method (described by marcus) will not give you a closed orbit.

To create an orbit simulator in VB6, you will need to use mathematical equations and algorithms to calculate the positions of the objects in the simulation. You will also need to use the built-in graphics and animation capabilities of VB6 to display the objects and their movements on the screen.
To make a realistic orbit simulator, it is important to use accurate and precise mathematical equations and algorithms. You should also consider factors such as gravity, speed, and mass in your calculations. Additionally, using realistic graphics and animations can enhance the overall experience for the user.
Yes, you can add multiple objects with different orbits in your VB6 orbit simulator. You will need to use arrays and loops to calculate and display the positions of each object separately. It is also important to consider the interactions and gravitational forces between the objects in your simulation.
To improve the performance of your VB6 orbit simulator, you can optimize your code by avoiding unnecessary calculations and using efficient algorithms. You can also limit the number of objects or decrease the complexity of the simulation to reduce the processing load. Additionally, using graphics and animations sparingly can help improve performance.
There are several resources and libraries available for creating VB6 orbit simulators, such as the DirectX library for graphics and animation. You can also find tutorials, sample codes, and forums online that can provide helpful tips and advice for creating your own orbit simulator in VB6.
