Cosmos Naive – a very basic demo of anaglyph stereoscopy with sprites in Excel


Reach out for your 3D goggles because this is a representation of the Cosmos through the eyes of a 5-year old. The model displays a few objects at various depths and move two of them back and forth on a chart to demonstrate the stereoscopic effect. Though very simplistic it is an excelent example of anaglyph stereoscopy in action showing you how it’s built. The farther the red and cyan (turquoise)…


Introduction to Anaglyph Stereoscopy in Excel – part #1: a more efficient composite rotation in the 3D Cartesian space


I made a stereoscopic model in October last year, however, choosing the wrong colors (red and blue on a black background, the effect was very weak (if any). This series was suggested to me last week by one of the guests here on the website, Don L. (thanks Don!), who sent me his stereoscopic cube. I opened the model, put on my goggles and his cube literally popped out of the…


Flight Simulator Tutorial #7 – upgrading the joystick chart, adding a reset button and a throttle scroll bar


This section displays the landscape on a 2D scatter chart and also upgrades the joystick chart by adding a dial behind the joystick image. This technique of using a stack of a back chart to display dial sprites and a front chart with transparent background to display various control devices, indicator needles and text will extensivly be used in this and future models.


Flight Simulator Tutorial #6 – macro review, scene derivation and integration, mapping of the 2D u-v data into a chartable 1D array, rejecting image artifacts


This section finishes the macro analysis and continues with the conversion of the u-v 2D formula array into a chartable 1D array. It also adds two columns to the chartable array, a masking condition for each triangle and masked u-coordinate which will throw out of the visible portion of the chart any shape which has a minimum of one vertex behind the virtual pilot. The section also explains the phenomenon…


Flight Simulator Tutorial #5 – the worksheet implementation of the perspective handling formulas and VBA the macros


This section explains the spreadsheet  implementation of the perspective rotation and translation formulas within the Present array and also the implementation of the 3D-2D conversion formulas within the Past array, then it goes on to presenting the VBA macros used (the Reset and JoyStick macros).

A First Flight Simulator Model in Excel


This is the first version of a 3D flight simulator in Excel. Start by adjusting the zoom on your file to fit the screen, so you can see the whole chart and the buttons underneath, then click “Reset” and then click the red dot in the center of the joystick. After that, the joystick handle will “stick” to your mouse pointer so your mouse becomes the airplane control. Back and forth mouse…
