[Robert Osfield]

Hi All,

Now back from my short holiday and have merged all the fixes submitted from
the community since rc7.


   - Zip file containing source code : OpenSceneGraph-3.4.0-rc8.zip
   <http://www.openscenegraph.org/downloads/developer_releases/OpenSceneGraph-3.4.0-rc8.zip>
   - Subversion tag for 3.4.0-rc8 : svn co
   http://svn.openscenegraph.org/osg/OpenSceneGraph/tags/OpenSceneGraph-3.4.
   <http://svn.openscenegraph.org/osg/OpenSceneGraph/tags/OpenSceneGraph-3.4.0-rc8>0-rc8
   OpenSceneGraph


I would very much appreciate testing from the community.  My aim is now to
get OSG-3.4 out the door early next week.

Cheers,

Robert.


ChangeLog since rc7:
2015-07-31 15:01  robert

    * CMakeLists.txt: Updated rc number to 8 for 3.4.9-rc8

2015-07-31 13:47  robert

    * CMakeModules/OsgAndroidMacroUtils.cmake: From Terry Welsh, "I
      downloaded the Android 3rdparty deps from here
      http://www.openscenegraph.org/index.php/download-section/dependencies
      but was not able to use them for a while. Attached are changes to
      OsgAndroidMacroUtils.cmake that allow the deps to be found by
      cmake.

      Specifically, all FIND_PATH commands require the
      NO_CMAKE_FIND_ROOT_PATH option to actually find paths. This is
      odd
      because if you inspect CMAKE_FIND_ROOT_PATH it appears to be
      empty. I
      would expect it to have no effect at all.

      I also needed to remove quotes from this line in order for
      headers to be found:

      set(FREETYPE_INCLUDE_DIRS "${FREETYPE_DIR}/include
      ${FREETYPE_DIR}/include/freetype/config")

      Assuming this script worked in the past, it seems like cmake
      behavior
      may have changed at some point. I'm using cmake version
      2.8.12.2."

    * src/osg/GLExtensions.cpp: From Jannik Heller, "Here is a patch
      for the S3TC capability check.

      On a Intel HD graphics Linux system with Mesa 10.1.3, I found
      that osg's Extensions::isTextureCompressionS3TCSupported()
      returned false, even though S3TC compressed textures *are* in
      fact working. I tested this by loading and rendering various
      DXT1, DXT3 and DXT5 compressed textures in the OSG.

      "glxinfo | grep s3tc" gives:
      GL_S3_s3tc

      Note, if I install the package "libtxc-dxtn-s2tc0", I get in
      addition:

      glxinfo | grep s3tc
      GL_EXT_texture_compression_s3tc
      GL_S3_s3tc

      However, S3TC compressed textures worked correctly within the OSG
      even without libtxc-dxtn-s2tc0 installed.

      I'm not sure what the differences between these extensions are,
      but based on the description at
      https://www.opengl.org/registry/specs/S3/s3tc.txt I would assume
      that both will work for OSG's purposes. The attached patch
      changes isTextureCompressionS3TCSupported() to accept either
      extension."

      src/osgPlugins/lua/LuaScriptEngine.cpp,
      src/osgViewer/ViewerEventHandlers.cpp: From Kristofer Tingdahl,
      warning fixes.
