[osg-users] How ca a subset of an vertex array marked as dirty ?

[Mathias Schiwago]

Hi,

my geometry has a quit large vertex array and uses VBOs. I want to update just a small subset of the array with new coordinates and let's OSG update the VBO accordingly. 

How can this be done without using direct OpenGL API ? 

I am using OSG 3.2.0.

Thank you!

Cheers,
Mathias
