No, there is no such plan to replace the OpenGL types by the vect types.
However, with vect, you don't really have to use the OpenGL types at all,
at least in normal circumstances.

Yes, AC-Vector is similar, but vect is older, more mature, and has *much*
more functionality.

hmatrix is a very different library: It is intended for large-scale linear
algebra (based on the scientific libraries BLAS, LAPACK, GSL). vect (and
AC-Vector) is intended specifically for low-dimensional (up to 4
dimensions) linear algebra (and vect is tailored specifically for
graphics). vect is also completely standalone (no dependencies), as opposed
to hmatrix.

Hi Balazs,<br>

That sounds nice, but is there any timeline for replacing types used by cur=

Since as far as I understand, vect-opengl gives just typecasts,<br>

Thus we have AC-Vector that serves similar purpose as vect (and probably fe=
