Raw Normal View History

Moved FGAircraftModel subsystem out into its own directory, and separated out a new class, FG3DModel, that allows any arbitrary 3D model to be positioned, oriented, and animated (not just the aircraft).

This patch includes the FGLocation class, a few fixes, cleanup in viewer code. Synced to CVS 19:36 EDT 2002-04-10 (after this evenings JSMsim and Base package updates). Description: Added FGLocation class which is new home for calculating matrix rotations. Viewer can now be configured to access rotations created by the model rather than repeating the same calculations again. Changed model initialization for the time being so that its location data is available for the viewer (currently required by other subsystems). At some point we can move this back to fg_init along with the viewer initialization. Seperated the update from the draw function in the model code. The viewer code needs the same matrix data, and moving the update portion at this time does not increase the number of matrix math iterations. Moved the model draw so that it always appears "in front" of lights and clouds. Reogranized viewer update routine for using the FGLocation class and simplified some more tasks. The routine is fairly easy to follow now, with the steps ordered and spelled out in comments. Viewmgr only updates the current (visible) view now, with the exception of an old reference to "chase view" that will be corrected in forthcoming changes. Also will be doing some work on the viewmgr outputs. Model is now clears the z-buffer in all modes. This will be changed with the next viewmgr update. The only side effect is that models always disappear when over 5km distant from the eye point (can't really see them anyway:-)). Other than a flag to indicate "internal" view I don't anticipate the configuration interface for viewmgr/views will be changed a lot for now. It is close to done. The next viewmgr update will however rework the outputs so you can expect that the data that viewmgr is writing to the property tree may change location. This code will run with the previous version of preferences.xml, but will run faster with the newer version. I am attaching a preferences.xml that should not be commited before the code. All the changes are in the /sim/view section and should show a simpler view configuration that references model locations. Note that I've added a 2nd tower view in "lookfrom" mode for illustration purposes. You can look around using the mouse. You may want to remove that or comment it out.

The 3D aircraft model scene is now managed by FGAircraftModel::update. We should do the same thing for the scenery, to simplify the top-level loop.
