Static Lissajous Emulators (2D and 3D)

September 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

September 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.  


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.
