Hi All, I've now tagged the OpenSceneGraph-2.5.4 developer release, you can grab it from:
http://www.openscenegraph.org/projects/osg/wiki/Downloads/DeveloperReleases Details: * OpenSceneGraph-2.5.4, released on 12th July 2008. OpenSceneGraph-2.5.4 introduces osg::KdTree, with automatic KdTree building on file loads, and automatic use of KdTree during osgUtil::IntersectionVisitor/LineSegmentIntersector traversals for significantly speeding up intersection tests. Also various bug and build fixes. source package : OpenSceneGraph-2.5.4.zip svn tag: svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.5.4 OpenSceneGraph Full ChangeLog since 2.5.3 below. Thanks to all the contributors and testers. On Monday I'll look at integrating osgWidgets, then once the build looks stable do another quick dev releases, say around Wednesday, then another dev release on Friday. The following Monday (21st July) I plan to make the OpenSceneGraph-2.6 branch, followed up by some quickl release candidates which we test through the week then tag the final 2.6 stable release on the Thursday or Friday (24th/25th July). If we miss making 2.6 within this next two week window then I'll have to tackle it in the week of the 4th to 8th August, as I'm away on holiday for a week with my family from the 27th July to 3rd August. This second window is not ideal though as lots of our able bodies will be preparing for and heading to Siggraph, so if we can we should try for this next two week window. Cheers, Robert. ------------------------------------------------------------ ChangeLog since 2.5.3: 2008-07-12 12:00 +0000 [r8570] robert: * 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" 2008-07-12 11:19 +0000 [r8569] robert: * Cleaned up osgkdtree example 2008-07-11 20:01 +0000 [r8568] robert: * Updated version numbers for dev release 2008-07-11 19:52 +0000 [r8567] robert: * From Adrain Egli, "i added a default scene with 7 different draggers attached. it's more easy to test the draggers." 2008-07-11 19:43 +0000 [r8566] robert: * 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." 2008-07-11 19:23 +0000 [r8565] robert: * 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. " 2008-07-11 17:46 +0000 [r8564] robert: * 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." 2008-07-11 17:41 +0000 [r8563] robert: * From Joakim Simmonsson, fixed various spelling typos in comments 2008-07-11 17:35 +0000 [r8562] robert: * From Mathias Froehlich, "Due to the recent data variance changes/discussion: Change the ac3d loader that can as such only deliver static models to set the data variance to static for the returned model.
