Modifications done in Micro Flight 5:

Terrain Engine:

* Terrain engine replaced, uses variable level of detail mesh and land texture.

* Land texture is generated by altitude and not by tiles.

* Land engine offers 150 km visibility, up to 50 km of fog distance.

* Land textures have two modes, dense and sparse.

* Land visible up to 65000 ft where globe model takes over.

* Default textures for land and sea added to graphics directory and allows
scenery with DTM matrix only to be appear with land textures.

* DTM scenery matrix is imported with accurate projection and
is placed correctly on world map.

* Moving from scenery to scenery is smooth and allows dense scenery to
exist inside another scenery, moving between adjacent DTM sceneries is
smooth.

Scenery design:

* Terrain engine can load objects with exact coordinates using file
objects.txt, this file has the same format as def files but has coordinates
instead of tile units.

* Objects.txt can have other object files inside instead of object name
using anyname.txt makes procedural object possible.

* Support for night objects added, any object can have "_n" version which
loads at night without lighting.

* Objects have an angle parameter added, objects are defined as:
Name, Pos_x, Pos_y, Pos_z, Angle, Scale_x, Scale_y, Scale_z.

* Lights have range parameter added, lights are defined as:
Light, Pos_x, Pos_y, Pos_z, Range, Red, Green, Blue

* FixedArray object added, allowing houses to be made, defined as:
FixeArray, Pos_x, Pos_y, Pos_z, Elements , Width, Height, Size.

* Surface object added, allowing taxiways of arbitrary shape, defined as:
Surface, Pos_x, Pos_y, Pos_z, Angle, Scale_x, Scale_y, Scale_z.

* Radio navigation aids added, a file called navaids.txt is read
from the scenery and loaded as navaids list, thress types of navaids are
supported, ADF, VOR, ILS.


User interface:

* Map has added design mode which allows to view tiles, and objects,
measure coordinates and reload the objects placed in the scenery.

* Map shows sceneries boundaries as well, photo real sceneries shown only
where actual photo exist.

* Map shows navigation aids - ADF, VOR, ILS.

* Map has added export function to export waypoints as VOR, Runways as ADF
and ILS pairs.

* Improved user interface for gliders selection, instead of three dialogs
one is used for selecting, adding, removing, towing, and adjusting gliders.

* Added radio navigation screen, using the menu NAV or the Y key, selection
is assigned to ADF, VOR, ILS instruments on the plane, also showing DME
measurement for NAV1, NAV2 on the plane.

* Adaptive Joystick mode was improved to allow for smooth dead zone transition,
this mode allows smooth non linear joystick input in X,Y,R axes.

* Added option for field of view selection, Realistic field of view selects
45 degree filed of view as default, while non realistic selects 60 degree filed
of view by default.


Graphics:

* Clouds were improved, added full coverage of all the scenery.

* Sea replaced with variable level of detail mesh,
sea and land intersection done with transparency map.

* Support for jpg files added, jpeg files can be used instead of bitmaps.
for land textures, objects and planes.

* Support for dds file added, any object or plane can use transparency maps.

* Added option to resize the user interface, called "Compact GUI"
inside graphics dialog.

* Drawing of smoke and missile trails was improved.

* Drawing of rain was improved to avoid "marching rain" artifacts.

* Drawing of close objects in dense fog was improved.

* Drawing of far objects from inside cockpit view was improved, blinking artifacts
problem resolved.

* Drawing of runways and surface objects is completely flat on the ground, allowing
better blending of runways and taxiways with ground.


Keys and controls:

* Added keys for showing useful dialogs, using keys P,O,I,U,Y,T,Q.

* Added option to prevent toggle of auto-pilot when switching planes,
called "Toggle auto pilot" in graphics dialog.

* Added Slew mode when no plane is selected, uses left mouse drag slews
inside the scenery, with speed depending of simulation rate.

* Left mouse drag adjusts chase distance in chase view.

* Added multiple viewpoint support for airplanes, Shift+F1 shows this menu
for adding, deleting and switching viewpoints, Shift Tab switches viewpoints
quickly.

* Joystick input is ignored until first input is detected.

* Helium balloon gas filled with F key, dumped with D key, this replaces the
joystick Y axis which now controls pitch.


Airplane improvements:

* Flight model was improved to prevent lock-ups, especially for helicopters.

* Added Ball instrument for better display of artificial horizon.

* Added Accelerometer for display of normal acceleration - called ACCEL.

* Added navigation instruments, and adjustable gyro compass.
instrument names are - GYRO, ADF, VOR, ILS, RMI, NSD, ADI.

* Engine, Autopilot and Light state are saved for all planes in flight.

* Cannon weapons simulated as part of airplane weapons.

* Cannons fire simultaneously.

* Ground handling and water handling improved.

* Bombs are simulated as part of airplane weapons.

* Smoke created on surface after bomb hits.

* CCIP ( continuously calculated impact point ) appears on HUD when bomb is selected.

* Helium balloons have now rudder and elevator control surfaces, flight model was
improved to allow pitch, yaw and roll, gas filling dumping done with keys F,D.

* Panel assigns the selected instruments to ADF, ILS/VOR/NAV1, VOR/NAV2.

* Radio navigation instruments have adjustable scale for HDG, OBS adjustment, this
adjustment is made using the left mouse dragging on the instrument.

* Radio navigation screen in the program adjusts radio frequency selection for the
radio instruments, and also resets the adjustment of the scale.

* All instruments were updated based upon actual instruments.

* All weapons were updated based on typical weapons specs.


Other improvements:

* Eight additional wind layers can be created, using the advanced weather options.

* Individual airplane replays can be saved and loaded.

* Replay can be loaded in original position or in current position.

* Flights are saved and loaded with replays that were loaded into them.

* Replay of flights or gliders made smooth without jumps.

* Flight path was optimized and can store very long path length.

* Flights are saved with radio navigation assignment and adjustment values.

* Flights save all airplane state variables, including flaps, trim and gear.
