Hello All,
I encountered a problem with osgUtil::Optimizer.
The merge of two Vec3 vertex arrays fails in:
optimizer.cpp: MergeArrayVisitor::_merge
The problem started when I changed the construction of a Geode from
having one Geometry to having several.
When I do not optimize there is no problem. Rendering is just fine. Also
no problems at shut-down and no memory leaks.
At first I suspected a memory management bug in my code, but I just
can't see it.
*This is roughly what I did before the problem:
*osg::Geode*
Construct(void)
{
osg::Geode* l_Geode = new osg::Geode;
osg::Geometry* l_Geometry = new osg::Geometry;
osg::Vec3Array* l_Vertices = new osg::Vec3Array;
l_Geometry->setVertexArray(l_Vertices);
for (..)
{
for (..)
{
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Geometry->addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::QUADS, l_Vertices.size()-4, 4));
}
}
l_Geode->addDrawable(l_Geometry);
return l_Geode;
}
*This is roughly what I do now, causing the problem:
*osg::Geode*
Construct(void)
{
osg::Geode* l_Geode = new osg::Geode;
osg::Geometry* l_Geometry = NULL;
osg::Vec3Array* l_Vertices = NULL;
for (..)
{
l_Geometry = new osg::Geometry;
l_Vertices = new osg::Vec3Array;
l_Geometry->setVertexArray(l_Vertices);
for (..)
{
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Vertices->push_back(..);
l_Geometry->addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::QUADS, l_Vertices.size()-4, 4));
}
l_Geode->addDrawable(l_Geometry);
}
return l_Geode;
}
I'm fairly new to OSG, so if someone could give me a pointer. That would
be much appreciated.
Serge
