Hi,
there are Build Issues with the current Trunk and the GL3 Option
osgText does not build due to glPushAttrib / glPopAttrib in
Text::renderWithDelayedDepthWrites.
osgSim OverlayNode Serializer uses Deprecated glTexEnv GL_DECAL Enum.
Fix for Text::renderWithDelayedDepthWrites:
void Text::renderWithDelayedDepthWrites(osg::State state, const osg::Vec4
colorMultiplier) const
{
#if !defined(OSG_GLES1_AVAILABLE) !defined(OSG_GLES2_AVAILABLE)
!defined(OSG_GL3_AVAILABLE)
glPushAttrib( _enableDepthWrites ? (GL_COLOR_BUFFER_BIT |
GL_DEPTH_BUFFER_BIT) : GL_DEPTH_BUFFER_BIT);
// Render to color buffer without writing to depth buffer.
glDepthMask(GL_FALSE);
drawTextWithBackdrop(state,colorMultiplier);
// Render to depth buffer if depth writes requested.
if( _enableDepthWrites )
{
glDepthMask(GL_TRUE);
glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE);
drawTextWithBackdrop(state,colorMultiplier);
}
glPopAttrib();
#else
OSG_NOTICE Warning: Text::renderWithDelayedDepthWrites(..) not
implemented. std::endl ;
#endif
}
Fix for osgSim::OverlayNode Serializer ( not sure if this one is sufficient,
but works )
#include osgSim/OverlayNode
#include osgDB/ObjectWrapper
#include osgDB/InputStream
#include osgDB/OutputStream
REGISTER_OBJECT_WRAPPER( osgSim_OverlayNode,
new osgSim::OverlayNode,
osgSim::OverlayNode,
osg::Object osg::Node osg::Group osgSim::OverlayNode
)
{
BEGIN_ENUM_SERIALIZER( OverlayTechnique,
OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY );
END_ENUM_SERIALIZER(); // _overlayTechnique
ADD_OBJECT_SERIALIZER( OverlaySubgraph, osg::Node, NULL ); //
_overlaySubgraph
#if !defined(OSG_GLES1_AVAILABLE) !defined(OSG_GLES2_AVAILABLE)
!defined(OSG_GL3_AVAILABLE)
ADD_GLENUM_SERIALIZER( TexEnvMode, GLenum, GL_DECAL ); // _texEnvMode
#endif
ADD_UINT_SERIALIZER( OverlayTextureUnit, 1 ); // _textureUnit
ADD_UINT_SERIALIZER( OverlayTextureSizeHint, 1024 ); // _textureSizeHint
ADD_VEC4_SERIALIZER( OverlayClearColor, osg::Vec4() ); //
_overlayClearColor
ADD_BOOL_SERIALIZER( ContinuousUpdate, false ); // _continuousUpdate
ADD_DOUBLE_SERIALIZER( OverlayBaseHeight, -100.0 ); // _overlayBaseHeight
}
Moreover, think it would be a good Idea to add an Option to CMakeLists whether
to build osgQT, as QT includes GL.h. No fix for that :-)
For completeness, this Thread explains how to build OSG with GL3 option on
Windows ( tweak of osg/GL , tweak of CMakeLists.txt ) :
