Hi Robert,
Just a quick note.
In OpenSceneGraph-3.6.2 in the mipmap.cpp module.
I got a warning
c:\apis\openscenegraph-3.6.2\src\osg\glu\libutil\mipmap.cpp(6490): warning
C4701: potentially uninitialized local variable 'outindex' used
I initialized the declaration on line 6116
To int outindex=0;
Everything works

Hi Robert,
I am new in OSG so please be patient. I am still reading the book.
Just to clarify I should replace in the class CSimpleInterimShadowTechnique
CSimpleInterimShadowTechnique();
CSimpleInterimShadowTechnique(const CSimpleInterimShadowTechnique&
es, const osg::CopyOp& copyop=osg::CopyOp::SHALLOW_COPY);
META_Object(osgShadow, CSimpleInterimShadowTechnique);
with
CSimpleInterimShadowTechnique();
CSimpleInterimShadowTechnique(const CSimpleInterimShadowTechnique& es, const
osg::CopyOp& copyop = osg::CopyOp::SHALLOW_COPY);
virtual bool isSameKindAs(const osg::Object* obj) const { return
dynamic_cast<const CSimpleInterimShadowTechnique*>(obj) != NULL; } \
virtual const char* libraryName() const { return "osgShadow"; }\
virtual const char* className() const { return
"CSimpleInterimShadowTechnique"; }
removing META_object
and also add
/** Resize any per context GLObject buffers to specified size. */
virtual void resizeGLObjectBuffers(unsigned int maxSize) = 0;
/** If State is non-zero, this function releases any associated
OpenGL objects for
* the specified graphics context. Otherwise, releases OpenGL
objects
* for all graphics contexts. */
virtual void releaseGLObjects(osg::State* = 0) const = 0;
to the class.
Do I have this right?
Thank you!
Cheers,
Herman

Hi Harman
There should be no need to replace the use of META_Object, the
original code should be fine. The only reason why META_Object macro
wasn't working is because the CSimpleInterimShadowTechnique doesn't
implement the pure virtual methods that have been added in 3.6.x - the
ones I mentioned above.
Have a look at the include/osgShadow/ShadowMap example as it
subclasses from ShadowTechnique is uses META_Objects and override the
required methods. Have a look at the src/osgShadow/ShadowMap.cpp to
see how the
resizeGLObjectBuffers and releaseGLObjects are implemented.

Seconded, yes.
You can also potentially make hierarchical structures of the graph to
improve the performance of the intersection process.
You would not need ODE.
You could even construct an OSG loader to deserialize the sphereville graph
natively so that you could use OSG's databasepager and LOD tools to roam
around the graph loading and unloading the bounds dynamically.

Sure it can do that. There is even an example in the repository for it:with geometry along the specified line segment?
