implementations being registered at the same time.
One usage case for this functionality to support usage of Wayland and X11 in the same version of the osgViewer.
As part of the new functionality there is now a osg::GraphicsContext::Traits::windowingSystemPreferrence string
that default to empty, but if defined will ensure that a specific WindowingSystemInterface is utilized when
you do a generic call like osg::createGraphicsContext().
Also implemented is standard proxy object for registering the new contexts and removing them automatically, and
declaration of standard graphicswindow_name() C entry point to help with static build linking.
This feature makes it easier to editor an presentation that is already running in Present3D, once the edits are done
pressing 'u' in Present3D then loads the file again.
"From I think that this piece of code in StateSet::setTextureAttributeAndModes is a copy&paste mistake:
OSG_NOTICE<<"Warning: non texture attribute '"<<attribute->className()<<"' passed to setTextureAttributeAndModes(unit,attr,value), "<<std::endl;
OSG_NOTICE<<" assuming setAttributeAndModes(attr,value) instead."<<std::endl;
OSG_NOTICE<<" please change calling code to use appropriate call."<<std::endl;
setAttribute(attribute,value);
As per the warning message it should be calling setAttributeAndModes(attribute,value); ."
As for motivation behind the change, I think it makes more sense that way because only the CullVisitor cares about rendering. Say an intersection visitor or update visitor only needs to traverse the subgraph once, not once for each pass. For these visitors there is no point in traversing the subgraph more than once, since it's exactly the same graph. Another motivation is the performance improvement had when an intersection visitor tests against a multipass Technique."
Note about mods by Robert Osfield, "Changed dyanmic_cast<> and check against getTraversalType() to utilize the new asCullVisitor() instead to improve efficiency."
The change I made is to check GL_QUERY_RESULT_AVAILABLE before retrieving the query, to ensure that there won't be a stall. If the query result is not available yet, we'll leave it alone and try again in the next frame.
Had to make a few more changes than I'd liked, mostly because the TestResult mechanism wasn't designed for holding on to query objects for more than one frame. As well, I'm thinking that RetrieveQueriesCallback and ClearQueriesCallback could be merged together, if we wanted to go for more refactoring. For though now my strategy is to make as little changes as possible. Let me know what you think of the patch."
In OSG 3.4, osgText::Text( ::_quadIndices) uses DrawElementsUInt that will fail on these devices and no text will appear - tested on Samsung Galaxy Trend 2 SM-G313HN.
When DrawElementsUInt is replaced with DrawElementsUShort it works, although I'm not sure if this can cause other problems with some fonts.
Fix:
- In include\osgText\Text, line 316:
replace: "osg::ref_ptr< osg::DrawElementsUInt > _quadIndices;"
with: "osg::ref_ptr< osg::DrawElementsUShort > _quadIndices;"
- In src\osgText\Text.cpp, line 2094:
replace: "_quadIndices = new DrawElementsUInt(PrimitiveSet::TRIANGLES);"
with: "_quadIndices = new DrawElementsUShort(PrimitiveSet::TRIANGLES);"
"
Currently the code looks like this:
Code:
DrawElementsUByte* elems = new DrawElementsUByte(PrimitiveSet::TRIANGLES);
elems->push_back(0);
elems->push_back(1);
elems->push_back(2);
elems->push_back(2);
elems->push_back(3);
elems->push_back(0);
geom->addPrimitiveSet(elems);
geom->addPrimitiveSet(new DrawArrays(PrimitiveSet::QUADS,0,4));
The second condition looked really strange (note the ! sign), and results in pretty much all code paths uses the first code. The correct version should probably be that only people with GLES1 or GLES2 should use GL_TRIANGLES to simulate quads. And all others should use the native support for GL_QUADS.

Font::getKerning(...), Font::getGlyph3D(...) doesn't ask for a font resolution so it uses the last font resolution requested by Font:: getGlyph(...).
This can leads to different results depending of the precedent call to Font::getGlyph(...).
See http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2016-January/271952.html for more infos.
This fix adds a font resolution parameter to Font::getKerning(...), Font::getGlyph3D(...) and to the font implementations.
This was made under the base revision r15182."

"
Removed old code intended to check the Geode parent of a Drawable to see if it's CullingActive is true as this was broken by the change osg::Drawable being derived from osg::Node rather than osg::Object.
The uniquify() method was not checking if the new name was actually in use or not.
Collada with rename option : Added an option to Collada writer, to rename uncommon IDs (geometries, materials...) to something more compatible (especially Google Earth).
Characters which may be interpreted as an URI are replaced with '_'. Useful if you want to ensure names having spaces or slashes to behave correctly. This may be undesired if original naming must be somewhat kept (hence making it an option)."
