Hi all,
I know a lot of people who are interested by the interpretation of pitch and
roll in STG files.
Currently pitch and roll doesn't exist in STG file. A good proverb say "do it
yourself", thus I implemented the pitch and roll interpretation in STG files.
The git diff is :
diff --git a/simgear/scene/tgdb/ReaderWriterSTG.cxx
b/simgear/scene/tgdb/ReaderWriterSTG.cxx
index 21a47ba..5b8945a 100644
--- a/simgear/scene/tgdb/ReaderWriterSTG.cxx
+++ b/simgear/scene/tgdb/ReaderWriterSTG.cxx
@@ -281,6 +281,18 @@ ReaderWriterSTG::readStgFile(const std::string&
absoluteFileName,
matrix = makeZUpFrame(SGGeod::fromDegM(lon, lat, elev));
matrix.preMultRotate(osg::Quat(SGMiscd::deg2rad(hdg),
osg::Vec3(0, 0, 1)));
+
+
+ if ( (in.peek() != '\n') ){
+ double pitch(0.0), roll(0.0);
+ in >> pitch >> roll;

+ matrix.preMultRotate(osg::Quat(SGMiscd::deg2rad(pitch),
+ osg::Vec3(1, 0, 0)));
+ matrix.preMultRotate(osg::Quat(SGMiscd::deg2rad(roll),
+ osg::Vec3(0, 1, 0)));
+ }
+
osg::MatrixTransform* matrixTransform;
matrixTransform = new osg::MatrixTransform(matrix);
As you can see, it's only 6 lines added. This code works for "old" and "new"
STG files.
Example of old STG files :
OBJECT_SHARED Models/Communications/radio-medium.xml -121.8425 37.111111 964.15
180
Example of new STG files :
OBJECT_SHARED Models/Communications/radio-medium.xml -121.8425 37.111111 964.15
180 45.0 25.0
Where pitch = 45.0 degrees and roll = 25 degree
Someone can add it in Simgear please ?
Cheers,
Clément
