Hi Robert,
Great work! I just have a few questions/comments.

Hi All,
I have just finished a rather intensive bout of work on the new
cleaned up osg::Geometry, one of the most challenging parts was
providing a fallback for the deprecated array indices and
BIND_PER_PRIMITIVE usage. The new osg::Geometry doesn't support
rendering of geometries with indices and BIND_PER_PRIMITIVE so one has
to convert geometries containing these over to OpenGL fast path
compliant forms using just straight vertex arrays and standard
glDrawArray/glDrawElements based primitives, and to ease this task I
have written a could of new methods to osg::Geometry:
/** Return true if the deprecated use array indicies or
BIND_PER_PRIMITIVE binding has been assigned to arrays.*/
bool containsDeprecatedData() const { return _containsDeprecatedData;
}
/** fallback for deprecated functionality. Return true if the
Geometry contains any array indices or BIND_PER_PRIMITIVE arrays. */
bool checkForDeprecatedData();
/** fallback for deprecated functionality. Removes any array
indices and BIND_PER_PRIMITIVE arrays.*/
void fixDeprecatedData();
What is the difference between containsDeprecatedData() and
checkForDeprecatedData()? I see that containsDeprecatedData() just
checks the flag, what does the latter do? Forgive me if this is obvious,
the names suggest the same operation to me.
I looked at the revision at
https://github.com/openscenegraph/osg/commit/95548b9cda28c1124fea2c09402547d018266384
but I could not find the implementations of the new member functions.
Also, the include guard in include/osg/Geometry got changed to
OSG_GEOMETRYNEW from OSG_GEOMETRY, was that intentional?
Regards,
Judson
