Hi (especially to Aurelien if he's reading), I'd like to understand the plan for support of instanced drawing in the revised Geometry and Array classes, using per-instance attribute arrays via divisors.
Also, if possible, I'd appreciated some suggestions for achieving the same in a custom drawable with older versions of OSG (perhaps as far back as 3.0!). I have the impression from other posts here that there is some hybrid approach where Arrays and PrimitveSets can still be used to specify the repeating geometry, but the per-instance attributes being specified manually? A pseudo-code, or even working-code example of this, would really enlighten me. Note I'm only concerned about platforms with support via glVertexAttribDivisor(ARB), since this covers everything I care about in practice - even compatibility mode on Apple with GL 2.1 support this via an extension.
