3-Body Planetary System with Options

Planetary model
10/08/2010

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….

Static Lissajous Emulators (2D and 3D)

09/29/2010

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

09/27/2010

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]

Roller Coaster

A roller coaster in Exel 2003 in 3-dimension (perspective view). To start de ride after download, click the little sun icon in the NE corner of the chart. Most of the calculations are done in the spreadsheet with very little VBA as a “glue”. The display is created on a plain 2D scatter plot. [sociallocker][/sociallocker]
