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.
The file osg-OpenSceneGraph-3.4.0\include\osg\Types
typedefs int8_t, int16_t, int32_t and int64_t
These are typedefed as signed __intX in several other places.
With VS2008, this causes an error "int8_t redifined, different basic types"
Explicitly declaring them signed fixes the error."
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);"
"
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."
