Hi Peter,

there is probably a little confusion.

No there is not - we have nviz in 5.1 that supports 3D vectors and then we have
nviz5.0
with Bob Covill's improvements and those two need to be merged before more work
is done,
in particular on integrating g3d.

It appears to me that merging grass5.1 and grass5.0 should
be a no. 1 priority right now before more work is done on each separately.
(e.g. if I want to do some enhancements to RST should I do it to s.surf.rst5.0 or
v.surf.rst5.1?)
I understand, that Radim does not want the merge before he has more of the vector
capabilities done,
but while the GRASS5.0 is being cleaned up, he may as well have enough done on
the vector side.
The milestones are set at http://grass.itc.it/grass51/index.html - maybe they
should be revised
and updated (I think there are few items even in phase 2 that are already done).

Glynn, Bernhard, do you have any advice on how to proceed with this?
It was already discussed but it ended up with no clear solution.

just a good advice on how and where to develop new capabilities in terms of
grass5.1 and grass5.0exp
would be helpful,

thanks a lot,

Helena

any advice

Is working on G3D, while Radim is working on GRASS 5.1 3D vectors.

Helena,

it is clear that there will be no general/automatic merge of the two
development lines grass 5.0 and grass 5.1 .

Grass is a huge project, we cannot completely avoid
that we need to port or backport in some areas where development is fast.

There is no general rule to decide on where to start working
with new features. It will be a case by case decision.

Here are at least some arguments:
If you need the features fast and for production and other people
this are arguments to take the 5.0 as a basis.
However you have to be prepared to to port it to 5.1 later.
If you find that you need features from GRASS that will only be
present in 5.1 this would be an argument to base it on 5.1
and help to organise to make 5.2 happen.

I don't want to merge all remaining vector modules just now,
but all rest may be moved from g50 to g51. As g51 is for development
only and it is easy to run g50 modules from g51, it is not problem that some
vector modules will be missing for next few months.
