ff38da1290 Refactor various NodeTracker and MatrixManipulator classes to use the osg::ObserverNodePath and osg::oberserver_ptr<> classes 2010-02-15 20:15:32 +00:00
Robert Osfield
4a567d9954 Introduced new osg::ObserverNodePath class that robustly manages a NodePath in a thread safe manner,
making it easier for users to track a NodePath even when nodes in the path get deleted.

644b2e15d1 Refactored the osg::Observer to introduce a new bool Observer::objectUnreferenced(void*) method that adds
the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted.

Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object.  This
makes observer_ptr<> more equivilant to boosts weak_ptr.

d6179e7eb5 Added osg:: qualifyer to OSG_NOTIFY macro 2010-02-15 11:36:05 +00:00
Robert Osfield
a673abac3d Introduced OSG_WARN, OSG_NOTICE, OSG_INFO, OSG_DEBUG convinience macros that map to OSG_NOTIFY(osg::WARN) etc.
Introduced the OSG_NOTIFY_DISABLE Cmake variable + include/osg/Config #define to control whether the OpenSceneGraph build
should disable the notification system completely.  By setting OSG_NOTIFY_DISABLE to ON in CMake and then rebuilding the
the OSG you can get a slightly smaller (~1%) and more slightly efficient library which can be good for shipping applications,
but with downside of reduced ability to detect runtime problems and their causes.

144d3e7af3 From Lars Nilsson, "Attached is a small program doing intersection calculations, both with and without KdTree. The geometry is a TRIANGLE_STRIP consisting of five vertices, all with the same rather high Z-value. If the intersection calculation uses KdTree, it fails. When I changed osg::Vec3 to osg::Vec3d in a few places in osg::KdTree it finds the correct intersection point."
From Robert Osfield, I didn't merge the change of parameter type of IntersectKdTree::intersect() as the internal maths is all done in Vec3s. Keeping Vec3 here hasn't effected the test results.

d891a56e8d From Wang Rui, "Attached are two simple modifications of osg::Sequence and
osg::Texture1D classes, for the reason of implementing the I/O
serialization feature. In the Sequence header, I've added some more
convenient functions: setTimeList/getTimeList,
setLoopMode/getLoopMode, setBegin/getBegin, setEnd/getEnd,
setSpeed/getSpeed and setNumRepeats/getNumRepeats.

In the Texture1D header, fixed:

inline void setTextureWidth(int width) const ...

to:

inline void setTextureWidth(int width) ..."

Notes from Robert Osfield, have gone a little further with these changes and have removed some of the original get methods that were out of step with the way the rest of the OSG manages the set/get property pairs.

a31aa512d7 From Rob Radtke, "I recently ran into some issues trying to save/load a scene graph as a .ive file. The problems came about because the scene graph contained depth textures in it. I have attached a patch (against the current revision: 10919) that fixes the issues that I encountered. Both attachments contain the same patch--one is a .zip file that contains the modified files and the other is a text patch file. Here is a summary of the changes I made:
1) Add getShadowComparison() accessor function to osg::Texture class
2) Modify ReaderWriterTiff::writeTifStream() and _readColor() (in Image.cpp) to handle pixelFormat==GL_DEPTH_COMPONENT as if it were GL_LUMINANCE
3) Modify the Texture classes of the ive and osg plug-ins so that they save/load the following Texture members: _use_shadow_comparison, _shadow_compare_func and _shadow_texture_mode

248a0813db From Lilith Bryant, "As discussed previously on the users list. Fixes the redundant calls to
glActiveTexture on every State::apply after more than one texunits have been
used.

This is against 2.9.6 (I think SVN head is the same)

Quick Synopsis:

New functions:

State::applyModeOnTexUnit
State::applyAttributeOnTexUnit
State::applyModeMapOnTexUnit
State::applyAttributeMapOnTexUnit
State::applyModeListOnTexUnit
State::applyAttributeListOnTexUnit

All copies of the normal versions, but they also set the active tex unit if
absolutely necessary (i.e. only if they call something OpenGL).

State::apply (*2)
State::applyTextureAttribute

Changed to call the above functions and no longer call setActiveTextureUnit
themselves.

State::setActiveTextureUnit

Made inline, so the benefit of having applyModeOnTexUnit (etc) inline
is retained.

47af634399 Refactored the way that osg::Image/ImageSequence manages the update callback that needs to be attached to Textures to make it possible to use the Image::update() mechansim in other subclasses from osg::Image.
To enable the automatic attachment of the required update callback to call osg::Image::update(..) subclasses from osg::Image will
need to implement the osg::Image::requestUpdateCall() and return true, and implement the osg::Image::update(NodeVisitor*) method to recieve the update call during the update traversal.

36b5e59019 From Paul Martz, "This change address the following issue: an app opens a Viewer on a multidisplay system, configured to setUpViewAcrossAllDisplays, with a non-default clear mask. In this case, OSG failed to propagate the clear mask to the slave Cameras, resulting in the clear mask being ignored. To fix this issue, this revision adds a new CullSettings::VariablesMask bit, CLEAR_MASK, to explicitly control inheritance of the clear mask. This bit is set by default, which means that the clear mask now inherits by default, whereas previously it did not." 2009-11-27 15:32:43 +00:00

c481f022e9 From Wojciech Lewandowski, "Building on earlier Paul's submission "[osg-users] Main branch MSFBO support change", I have added implicit buffer mask variables to DisplaySettings for setting global defaults for Camera FBOs. These mask variables are named after variables in Camera class. In Paul's submission they were named _renderBufferMask & _resolveBufferMask but I renamed them to _implicitBufferAttachmentRenderMask & _implicitBufferAttachmentResolveMask. DisplaySettings implementation includes reading of environment vars and command line options. Setters and getters follow typical OSG naming convention. I also updated names of ImplictBufferAttachment enum bits to match changed naming scheme.
DisplaySettings now define COLOR and DEPTH as defaults for implicit buffers. Consequently Camera by default uses the same defaults through USE_DISPLAY_SETTINGS_MASK. However, particular Camera mask can be easily overriden through Camera::setImplicitBufferAttachmentMask method. I hope, that in this way we can have global control over implicit buffer defaults, and we can still retain fine grained control at Camera level.

I have also replaced original unsigned ints used to store masks to signed ints because complier resolves enums as signed integer (I got a number of warnings with unsigned int)."

b7cabac990 From Mathias Froechlich, "Attached the collected fixes I needed to compile with all of them.
Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."

The Texture Pool can be enabled by setting the env var OSG_TEXTURE_POOL_SIZE=size_in_bytes.
Note, setting a size of 1 will result in the TexturePool allocating the minimum number of
textures it can without having to reuse TextureObjects from within the same frame.

c56dd6faa5 From Michael Platings, "the DAE importer was crashing when calling osg::Object::setName with a null pointer argument.
