This is an upgrade from the first part in the sense that it can be adjusted to have more delay based inverters in the feedback (14).
An interactive animated demo of the gated ring oscillator in Excel 2003 based on the previous tutorial. This model stands out because of the real time schematic animation.
This is the fourth part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.
In this version, the vertical joystick movement controls the incidence of both the main wing and the horizontal stabilizer (opposite variation) and the horizontal movement of the joystick controls the position of the center of mass.
This is an upgraded version of the aeroscope. Besides improving of certain aspects of the old version, this version has both the main wing and the horizontal stabilizer controlled by a virtual joystick (presented on this blog before and used extensively). The horizontal movement of the joystick controlls the angle of attack of the main wing and the vertical movement controlls the angle of attack of the horizontal stabilizer. I…
In this section, a joystick is added to the model which controlls the yaw rate and the pitch rate (not the angles!) of the stereoscopic cube. This joystick was used before in a dedicated tutorial and in the flight simulator tutorial. Its importance in future models can not be underestimated, hence I decided to cover this virtual device again. Use your 3D glasses while running the mkodel.
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.
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…
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). The PDF and XLF files were updated -04/22/2011, 5:20 pm MST.
This section explains the top level functionality of the model, it also allocates the data and formula arrays needed for manipulating the scene image. The roll rate, pitch rate and throttle formulas are implemented in the worksheet.
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…
This section deals with a simple method of creating the appearance of scene movement during the flight. Beside reviewing standandard rotation and translation formulas described before on this blog, the presentation begins to explain how to apply numerical-like methods to create a live and interactive model.
This is the second part of a tutorial explaining the creation of an “in-cockpit” flight simulator (versus the remote control simulator) model in Excel 2003. This section introduces some basic piloting background and nomenclature.
This is the first section of a tutorial explaining how to build a 3D flight simulator in Excel. This part deals with creating a joystick and a triangular ground mesh. The joystick model was explained in a previous post from January 2011 and the ground mesh was already used in the 3D roller-coaster. Please be aware that both the PDF and Excel files for this section have been updated on 4/13/2011 at 7:15 pm.
Hello everybody, this is a tutorial in which a virtual Excel joystick controlled by mouse movements on a scatter chart has been demonstrated . While in operation, a macro updates the coordinates of the pointer in two spreadsheet cells. The two coordinates are then incorporated in formulas which limit the range of motion of the joystick. Just like a real device the stick head movement is confined within a square (with a side…
