of rotations around X, Y, and X axes.

|
* Updates to sky dome modeling and make cloud layers follow the curve
|
|
of the earth (sort of.)
|

|
|
effects to make them more realistic and lifelike.

management code from FlightGear into SimGear and did a substantial
|
|
amount of restructuring and dependency clean up in the process.

management, basic model and model animation management, sky
|
|
rendering, and low level loaders for the "TerraGear" tile object format.
|
|

|
|
property variants. You can still do these things, but extra states
|
|
are no longer set up automatically.

* Removed 3d clouds from the default build ... these need a maintainer
|
|
or better yet, a complete plib-based rewrite.
|
|
* Moved the FlightGear sound effect manager code over to SimGear.
|
|
* Updated the cloud layer surface to better follow the inverted bowl

|
|
sunset/sunrise coloring.
|
|
* Fixed an obscure bug in cloud texture loading which caused each
|
|
cloud texture to be loaded 5 times. Ouch!

|
|
initialized.

|
* Various property manager fixes and improvements.

New in 0.0.18
|
|
* April 20, 2002
|
|
|
|
* Created a src/libs subdirectory for several packages that need to be
|
|
installed by the user but are used by many other packages and may already
|

|
|
if the user needs to build and install these.
|
|
* Upgrade to zlib-1.1.4 (security fix)
|
|
* Upgrade to metakit-2.4.2-32.tar.gz (latest upstream release)

* Additions to the binary file format to make it *much* more flexible.
|
|
For each major primitive type: points, triangles, fans, and strips, you
|
|
can specify an index list of vertices, normals, colors, and texture
|
|
coordinates. You can skip any of these you like to save on space.
|
|
* Added support for new file features in the binary -> ascii scenery file
|
|
decoder.
|
|
* Various code clean ups.
|
|

|
|
cards.

|
|
|
|
|
|
New in 0.0.16

* July 12, 2001
|

|
|
* Added support for RedHat package building contributed by Habibie
|
|
<habibie@MailandNews.com>
|
|
* Added gdbm to SimGear. Many systems will already have gdbm installed so

it is only built if it doesn't already exist on the user's platform.
|
|
gdbm is a set of database routines that use extendible hashing and works
|
|
similar to the standard UNIX dbm routines. This guarantees the availability
|
|
of gdbm to any application that uses SimGear.
