Using VSPAero to generate an aerodynamic model for JSBSim in FlightGear

Research into alternative methods of building aerodynamic models.

One of the challenges, probably the biggest single challenge, presented to an aircraft modeler is to make a representative FDM from any data that can be collected from publicly available sources. When there isn’t much data it has been a point of much discussion whether to use YAsim or to use a JBSSim model created with Aeromatic, Aeromatic++, DATCOM, or DATCOM+.

FlightGear: Using canvas in a 3d instrument


Currently the usual way of making an instrument in FlightGear is to draw a 3D model, texture it appropriate and animate the individual elements. For needles this usually means a rotation, and for drums a texture map translation. This workflow is well understood and works really well and what I’m presenting here isn’t intended to replace this.

Canvas allows us to render a 2D element onto a 3D quad.

Object event bus; Emesary: Nasal implementation for FlightGear

I’ve been recently looking at how to improve the way that the F-14 is built after starting to integrate the enhancements that Fabien has made to the radar system.

The trouble is that the F-14 is currently all very interdependent and would massively benefit from being decoupled. This is ideally suited to my standard solution to this sort of problem Emesary


Flightgear Interior shadow cubemap kit

This is a kit for making an interior shadow for the Effects/model-interior in Flightgear 3.6

Steps are.

  1. Load the interior-shadow-cubemap-creator.blend
  2. Import your model.
  3. Place the camera at the correct place (see the F-15 reference picture)
  4. Use the animate button – this will create 6 correctly oriented png files
  5. Use the properties to find the X,Y,Z of the camera
  6. Modify interior-shadow.eff to have the correct coordinates.
  7. Move the 6 png files to the appropriate place; I use Model/Effects/inteior
