POV-Team Status Report - September 1, 2000

Dear POV-Ray Community,

Thank you for all of your enthusiastic support for POV-Ray.  It is because
of you that this labor of love continues to exist and grow.  As many of
you know, our next release, POV-Ray 3.5, is currently in development, and
POV-Ray 4.0 is planned as a major rewrite of the core of POV-Ray.  We are
providing this status report to let the community know how things are
progressing.  Thank you all again for your support and patience.

The POV-Team

----POV-Ray 3.5 Status----

POV-Ray 3.5 is a work that will be somewhat similar to the unofficial
compile known as MegaPov.  POV-Ray 3.5 will be more mature and stable than

Work on POV-Ray 3.5 is progressing slowly but steadily. POV-Ray 3.5 will
contain many of the features of MegaPOV 0.5a, as described in the lists at
the end of this message. Please be aware that this feature list is
currently FIXED.  Each feature in MegaPov was carefully considered for
inclusion, and there are very good reasons why certain features have been
left out.  We are NOT requesting any discussion about features for 3.5.
Again, this list is FIXED.

The primary work on 3.5 is done, but quite a bit of work remains.  First,
we have a long list of bugs that we need to fix.  Second, some of the
features (such as light groups) are being enhanced and improved.  Third,
documentation still needs to be written. (The MegaPov documentation often
leaves a lot to be desired)  Fourth, the graphical interfaces for our
various supported platforms need to be updated.  Finally, all of this will
need to be packaged together into a final distribution.

----POV-Ray 4 Status----

Work on POV-Ray 4 has not yet begun.  However, there has been some
discussion that we feel is of interest to the community.

First, we have been discussing using a new license for 4.  Various
open-source licenses are under consideration.  We might instead use an
updated version of POVLEGAL.  No conclusions have been reached so far, but
the topic is under discussion within the POV-Team.

Second, we are also hoping to use a much more open development model for
POV 4, with public read access to our source-revision tree.  System
analysis, design, and implementation of POV 4 will be a very large task,
and this is one way we hope to speed it up.  This open development model
would also hopefully provide development releases (snapshots) more quickly
to the power-user community, similar to what MegaPov offers now.

Third, our most recent musings about POV-Ray 4 lean towards a major
reworking of the POV Scene Description Language.  This means that POV 4
may not be fully backwards compatible with old scenes.  If that is the
case, we will plan to provide an official conversion utility that will
convert old scenes into the new syntax, or provide some other means of
importing old scenes.

Finally, the POV-Team is currently not going to be involved in any public
discussion about POV 4.  We need to focus our efforts on POV 3.5.  Only
after the release of POV 3.5 will work on version 4 begin.  The community
can feel free to discuss this topic, but should not expect the POV-Team to
read such discussions at this time.
