3-Body Planetary System with Options

Planetary model

Here is a 3-body system with 3D graphics. I made it about 2 years ago but I’ve been updating it lately. This model  works at about 30 frames/second in Excel 2003 on a modern PC. In Excel 2007 it will run 10-15 times slower. I know 2010 is a lot faster than 2007. I’ve just bought a legit copy for 50$ but I didn’t have a chance to install it yet. I need to add  few more features….


Dynamic Lissajous Emulator


This is a dynamic Lissajous emulator in the sense that the waveform is obtained by combining 2 time varying sinusoidal waves with different frequencies. [sociallocker][/sociallocker]


Static Lissajous Emulators (2D and 3D)


This is a static Lissajous emulator in the sense that the waveform is obtained by combining 2 static sinusoidal waves with different frequencies. As a paranthesis, I will be preparing a dynamic version which will look just like the wave shape seen on a real oscilloscope. The file presented here has two different worksheets, the first one contains a classic 2D Lissajous figure and the second one has a 3D Lissajous pattern obtained from three different…


Basic 3D-2D (Perspective) Visualization


The first two worksheets of this Excel workbook illustrate the creation and display of a rectangle by using a 2D scatter plot. They also show how to adjust its size, translate and rotate it. In the third worksheet a wire-frame cube is created. 3D-2D persective calculations are done. The cube can be zoomed and it can also be rotated in azimuth and altitude using simple macros. [sociallocker][/sociallocker]
