[osg-users] update slave camera with frame scheme ON_DEMAND

[Gianni Ambrosio]

OK Robert,
no problem, I thought there could be a way to improve the existing OSG code so that other users would not struggle like me because slave cameras are updated before the master camera. From my point of view the default behavior should comply with the common concept that the master gives the rules, then slaves depend on the master. So slave cameras may depend on the master camera and not vice versa. On this bases the master camera should be updated first, then the slaves.
I also had in mind another scenario (think of a rearview mirror of a car) in which, in addition to my scenario, the slave camera shares the scene with the master camera. I would say the slave camera depends on the master camera and I expect the master is updated first so that the slave can use correct master camera values.

Anyway, thank you for your time and answers.

Gianni
