(with a great 'crease angle' feature), which will crash if the normal
array is already set but without BIND_PER_VERTEX. I just believe that
we should reallocate the normal array in these cases, as the old
implementation does.

hpux. I have skipped irix this time as irix is too dead to keep osg building
there.
As usual, solaris does not like member templates in stl containers.
Some headers missing and link problems due to missing libraries."
* support for NPOT-textures on IOS
* support for FBOs (only renderToTexture for now) on IOS (should work
for other OpenGL ES 1/2 targets, too)
* FileUtils-support for IOS"
- Algorithm doesn't try to merge double and single precision arrays together
- Algorithm doesn't try to merge incompatible geometries (ex: one with "vertices + texoords", and another with only vertices)
2. Better TextureAtlasBuilder
Algorithm is still sub-optimal, but it now tries to fill more blanks, using "unused space in the current line".
(Don't know if I already submitted it, but I guess not)
One day, someone should try to find a good solution to this NP-problem... For instance : http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.140.200&rep=rep1&type=pdf

to download the texture object to graphics card.
Calling IncrementalCompileOperation::assignForceTextureDownloadGeometry() assigns a geometry

changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.
submission email from Nathan: "I discovered a problem with POINT_ROT_EYE billboards in IntersectionVisitor: because we pass in just the model matrix to Billboard::computeBillboardMatrix, the billboard gets the wrong up vector. It really needs to take the view matrix into account to get the correct up vector.
This version of IntersectionVisitor.cpp is made against today's SVN. It corrects the problem by computing the billboard matrix using the complete modelview, and then multiplies by the inverse of the view matrix before pushing onto IntersectionVisitor's model stack. The only code I changed is in apply(Billboard&)."
notes from Robert, refactored the matrix multiplication code and the use of RefMatrix to make Nathan's changes more efficient.
Texture2DMultismaple as name suggests provides means to directly access subsamples of rendered FBO target. (GLSL 1.5 texelFetch call).
Recently I was working on deferred renderer with OSG, during that I noticed there is no support for multisampled textures (GL_ARB_texture_multisample extension). After consultations with Paul Martz and Wojtek Lewandowski I added Texture2DMultisample class and made few necessary changes around osg::FrameBufferObject, osg::Texture and osgUtil::RenderStage classes."
and from follow email:
"Fixed. According to ARB_texture_multisample extension specification multisample textures don't need TexParameters since they can only be fetched with texelFetch."
* Change OcclusionQueryNode::getPassed to take a NodeVisitor rather than the distance from BS center to the eye point. Change where CullVisitor calls this method to use the new parameters.
* getPassed now exits early and returns true to avoid blinking / blink-in of geometry for the first frame or for out-of-range LOD children coming back into view.
* getPassed now considers the distance from the near plane to the bounding sphere (rather than eye point to bounding sphere) when determining if the viewer is "inside" the bounding sphere or not."

10915 (5 Jan 2010): "Added support for call root Camera CullCallbacks"
It causes a segfault in osgViewer based apps on our linux system (OSG_STEREO=ON OSG_STEREO_MODE=QUAD_BUFFER)
Problem does not show when OSG_STEREO=OFF.

Looks like a typo, and removing the _ does fix the problem."
