[Boost-users] uBLAS compatible to OpenGL?

Hi,

is the uBLAS library memory compatible to OpenGL vector and matrix 
operations? I'd like to use a single representation for both internal 
maths and the rendering interface of my application. OpenGL expects a 
pointer to a float or double C-array. For example 4x4 matrices are 
stored linearly as 16 values. When using std::vector<T> or 
bounded_array<T> as storage, is there a guarantee that m(0,0) is a 
reference to the first element of an array of (at least) 16 values that 
equal the linearized matrix elements?  Or is there another way to get 
access to the low-level storage if it has a compatible memory layout? If 
there isn't, is it possible customize the uBLAS library by an additional 
"storage organization" or "adapted array" class?

best regards,
Malte
