4ca61c38f0 From Doug McCorkle, "Attached is patch that corrects/improves the following issues with the OBJ loader: 
1. Added options to control wether the osgUtil::Tessellator or osgUtil::TriStripVisitor are run. By default they still run just as before.
2. Added support for the Emissive material. The data was being read from the mtl file but was never being applied to the model.
3. This is the main bug addressed, when a model is read in with an alpha value specified like:

newmtl Material__8
       Ns 24
       d 0.33
       illum 2
       Kd 0.204 0.204 0.204
       Ks 0 0 0
       Ka 0.153 0.153 0.153

where the alpha value is d. The loader would then overwrite the alpha value when reading the diffuse, specular, and ambient colors. I have changed all the material color readers to only set the values they read and to use the default colors specified in the constructor of the obj class. With these changes, the obj reader now handles opacity correctly if the alpha value is specified before the material colo"

2b5708888e From Adrain Egli, "i added a default scene with 7 different draggers attached. it's more easy to test the draggers." 2008-07-11 19:52:25 +00:00

360e7629d0 From Christophe Loustaunau, "For our application, we need to write tiff file in floats. I have change a little bit the readerWritterTiff : 
It check the data type of the image ( img.getDataType() ) and if it's GL_FLOAT :It save the tiff with float values.
Otherwise it does the same thing as before."

0e2dea9a39 From Liang Aibin, " In lastest svn version of OSG, the .ive plugin missing osg::Light, it 
does not process I/O for osg::Light. Now I have fixed it as follows:
 
2. In DataInputStream.cpp, I add support code in DataInputStream::readStateAttribute
    for osg::Light.
 
3. In DataOutputStream.cpp, I add support code in DataOutputStream::writeStateAttribute
    for osg::Light.

ef1ee63f03 From Joakim Simmonson, 
"Opcodes.h:
* Added INVALID_OP as -1 in the Opcodes enum. Note that INVALID_OP is not an actual opcode defined in the OpenFlight format. The purpose of INVALID_OP is to mark an opcode variable as invalid or uninitialized.

ReaderWriterFLT.cpp:
* The header node is returned if it exists, even if the file does not contain a node hierarchy. The old behaviour returned a ERROR_IN_READING_FILE error.
* Changed opcodes initialized to -1 to the new enum value INVALID_OP."

161e01dc5d From Mathias Froehlich, "Due to the recent data variance changes/discussion:

data variance to static for the returned model.
