Hi

 

I am trying to do instancing in GLES 2.0. I know, that there is no direct support (glDrawElementInstanced). So what I want to do is duplicate model in VB up to count of my instances. In second VB I will have all positions (for each vertex, its just 2D coordinate).

Now I want to do this during application runtime from some generated geometry. But geometry is only in VB / IB and I can not found a way, how to read back or duplicate it in VB ?

 

Thanks
