Since not everybody has Excel and more and more people are on the dumbed down new versions (2007 and 2010) I am presenting these previews to give the readers a feel of the real speed and feel of some of the models in older Excel versions (in this case 2003). This preview refers to an older model. [sociallocker][/sociallocker]
This is an older model of planetary motion in 3D containing eight planets. A video preview can be watched here. [sociallocker][/sociallocker]
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….
This is an Excel workbook containing a dynamic model of a basic binary planetary system. [sociallocker][/sociallocker]
