[osg-users] OpenSceneGraph-3.0.1 released!

2011-07-31 Thread Robert Osfield 
Hi All,

Just one month after OpenSceneGraph-3.0.0 I'm a little amazed to
announce the release of 3.0.1 - a binary compatible maintenance
release, I believe this might well be a record for most speedy turned
around of stable release ;-)

The main changes are :

   Bug fixes to the new serializers and associated .osgb, .osgt and
.osgx formats.
   Improvements to the DCMTK based dicom plugin that vastly improves
the handling of scaling in dicom files so that a wider range of dicom
files are handled well.
   Shader tweak to osgShadow's handling of spot lights when doing view
dependent shadow map algorithms.
   Improved handling of initial bounding volume computation for view
dependent text scaling/orientation.
   Improvements in handling of different GLES builds


Thanks to all that have tested and provided fixes for this release,

Cheers,
Robert.


Full ChangeLog since 3.0.0 :

2011-07-31 07:50  robert

* CMakeLists.txt: Changed release candidate numbe for 3.0.1
  release.

2011-07-31 07:48  robert

* src/osgShadow/StandardShadowMap.cpp: Changed the handling of the
  ambient contribution of light to avoid lighting errors in the
  shadowed region outside a spointlight.

2011-07-29 07:44  robert

* src/osgViewer/ViewerEventHandlers.cpp: Merged from svn/trunk
  revision 12735, fixed console output of end of frame barrier
  position.

2011-07-28 16:59  robert

* AUTHORS.txt, CMakeLists.txt, ChangeLog: Updated ChangeLog and
  release candidate number for 3.0.1-rc3

2011-07-28 16:41  robert

* src/osgPlugins/dicom/ReaderWriterDICOM.cpp: Improved the handling
  of scaling of dicom imagery.

2011-07-28 12:08  robert

* src/osgViewer/GraphicsWindowX11.cpp: Merged from svn/trunk
  revision 12722. Refectored the EGL setup so that it's honours the
  Traits values.

2011-07-28 11:05  robert

* src/osg/Texture.cpp, src/osgWrappers/serializers/osg/Texture.cpp:
  Merged from svn/trunk, revision 12727, Reverted the change to the
  default setting of _resizeNonPowerOfTwoHint back to true for all
  platforms to ensure the
  same behaivour across platforms, something that can be achieved
  now thanks to the integrated GLU library.

  Corrected the default of the ResizeNonPowerOfTwoHint to true to
  reflect the actual default setting set by the
  Texture default constructor.

2011-07-28 08:19  robert

* src/osgDB/ObjectWrapper.cpp: From Johannes Baeuerle, merged from
  svn/trunk revision 12725, in the file
  src/osgDB/ObjectWrapper.cpp, where the GlobalLookupTable for gl
  enums for serialization purposes is defined, some of the
  compressed texture formats are missing. I added enums for the pvr
  and etc formats.

2011-07-28 07:47  robert

* src/osgViewer/View.cpp: From Jason Beverage, merged from
  svn/trunk revision 12723, Here is a small fix for
  getCameraContainingPosition. getXMin was
  being used in a case where getYMin should be used instead.

2011-07-25 19:28  robert

* AUTHORS.txt, ChangeLog: Updated ChangeLog and AUTHORS file for
  3.0.1-rc2

2011-07-25 18:39  robert

* CMakeLists.txt: Updated release candidate number

2011-07-25 17:08  robert

* src/osgViewer/Renderer.cpp: Merged from svn/trunk revision 12818,
  Fixed stats bug where not all stats fields were being collected
  by the cull_draw() method used in the SingleThreaded and
  CullDrawThreadPerContext threading models.

2011-07-22 09:28  robert

* src/osg/Texture.cpp: From Alexander Irion, merged from svn/trunk
  revision 12716, Texture borders are not supported in ES.

  _isTextureBorderClampSupported is set to TRUE in Texture.cpp,
  because of the version number check (GL VERSION = 1.3).

  This leads to an invalid enum error, when GL_TEXTURE_BORDER_COLOR
  is tried to set.

2011-07-22 08:26  robert

* src/osgViewer/ViewerEventHandlers.cpp: Merged from svn/trunk
  revision 12714, In the RecordCameraPathhandler fixed the
  handling of pressing 'Z' before 'z' which was causing the view
  to be reset to 0,0,0 by AnimationPathManipualtor with an empty
  AnimationPath.

2011-07-21 09:54  robert

* AUTHORS.txt, CMakeLists.txt, ChangeLog,
  applications/osgversion/Contributors.cpp, include/osg/Version:
  Updated ChangeLog, Version and AUTHORS file for 3.0.1-rc1

2011-07-21 09:19  robert

* src/osgText/TextBase.cpp: Merged from svn/trunk, workaround to
  culling issues assocaited with text that is set to scale relative
  to screen coords or is rotated to the screen.

2011-07-21 09:10  robert

* src/osgPlugins/vrml/ReaderWriterVRML2.cpp: From Mathias
  Froehlich, merged

Dear Jsaon,
thank you very very much. I had used another method to implement my needs. But 
i also read the example you recommanded. Thank you very much for you kindness 
answer.

Thank you!

[osg-users] [vpb] vector layer made by osgGIS take too much cpu usage

2011-07-31 Thread Lv Qing 
Hi,

I use vpb made a globle Earth model which size is about 3G,when I use osgviewer 
to view the model ,it took me only 10%~15% cpu usage. 

[img]http://wush.net/trac/osggis/browser/images/Round1.jpg?format=raw[/img]

then I use osgGIS to make a layer model base on the globle Earth model and a 
country boundries .shp vector file,the layer model is about 25 MB. 

when I use osgviewer to view the layer model ,it took me 50%~65% cpu usage!woo~ 

Is there something wrong about osgGIS or osg itself?Is there a better 
solution? 

... 


Thank you!

Cheers,
Lv[img][/img]
