93e6a59c9a From Aurelien Albert, "There is a little bug in the osg::Group::insertChild method : 
If the index is more than the size of _children vector, the new child is pushed at the end of the vector, but the index value is unmodified, so an incorrect value is passed to the "childInserted" method."

26a8f63212 From Wang Rui, "In the attached files I've added the Compute Shader support for OSG, as well as serializer updates and a new osgcomputeshaders example. My submission also include a setComputeGroups() function in Program for setting compute-shader work groups, and a bindToImageUnit() function in Texture for binding textures as image variables in shaders. 
All code are tested on Windows 7 + NVIDIA GFX 570 with the latest GeForce 310.70 Driver (BETA), which could support OpenGL 4.3.

Compute shader information can be found at "http://www.opengl.org/registry/specs/ARB/compute_shader.txt"

eed71f647d From Stephan Huber, "* imageio: removed ReaderWriterImageIO_IOS.cpp, refactored ReaderWriterImageIO to work on OS X and IOS 
* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)
* SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO)
* RestHttp: mouse-motion-events get interpolated
* RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event
* modified some CMakeModules to work correctly when compiling for IOS
* fixed a compile-error for IOS in GraphicsWindowIOS
* some minor bugfixes"

1796d55bea From Stephan Huber, OSX and iOS Video support via a QTKit plugin from OSX 10.7 and before, and an AVFoundation plugin for iOS and OSX10.8 and later. 2012-10-02 14:07:12 +00:00

4896edda56 From Thomas Hogarth, "Apple have decided in their eternal wisdom to do away with separate depth and stencil buffers on iOS from version 5 and above. 
Attached are changes to GraphicsWindowIOS.mm to support setting up the new buffer type when compiling for iOS5,
also attached is a small change to FrameBufferObject.cpp to report support for packed depth stencil via the
GL_OES_packed_depth_stencil extension.

For anyone reading this you can attach a packed depth stencil to your FBO like so

_rttCamera->attach( osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, GL_DEPTH24_STENCIL8_EXT );

Luckily GL_DEPTH24_STENCIL8_EXT happens to have the same value as iOSs GL_DEPTH24_STENCIL8_OES"

0a746faa2d Introduced Texture::Extensions::s/getPreferGenerateMipmapSGISForPowerOfTwo() flag that defaults to false for Radeon, true elsewhere. 
This is used to workaround mipmapping bugs with ATI/AMD cards.

- add non square matrix
- add double
- add all uniform type available in OpenGL 4.2
- backward compatibility for Matrixd to set/get an float uniform matrix
- update of IVE / Wrapper ReadWriter

implementation of AtomicCounterBuffer based on BufferIndexBinding

add example that use AtomicCounterBuffer and show rendering order of fragments,
original idea from geeks3d.com."

48b9b25805 From Johannes Baeurele, "The osg::Image class now contains a 'supportsTextureSubloading()' method that is used inside the Texture2D::apply method. For now it only checks for the etc1 format in which case it returns 'false'. All other formats lead to a return value of 'true'. 
Without the change the application does not work properly. First I get the notification that an OpenGL error occured. After some more of this error messages I see broken textures on the screen. With the changes attached to this message my application works as intended."

Note from Robert Osfield, changed the Image::supportsTextureSubloading() to be const and to be implemented in the .cpp rather than inline.

4457d2a145 From Colin McDonald, "Upgrading to OpenSceneGraph 3.0.1, texture mip mapping stopped 
working on some junk low-end graphics cards which I still have to
support.  They worked ok with osg 2.8 and earlier.

The problem turned out to be with gl proxy textures, which are
unreliable on those devices.  Proxy textures are used by the glu
mipmap build routines to determine if a texture size is
supported. The external glu library had a nice fallback
behaviour, so that if proxy textures didn't work then the mipmap
texture was still created.  But in the work on the new embedded
glu routines that fallback behaviour has been inadvertently
lost.  I have restored the fallback in
src/osg/glu/libutil/mipmap.cpp.  It doesn't add any extra
complexity."
