Not that this is much help to
you, but I want you to know that it's not a lost cause: I have successfully
run my Java3D apps on NT4 machines with a variety of video cards, some
accelerated, some horribly not. I haven't encountered any major problems. I
think you may have gotten unlucky with your customer's
configuration. For reference, my machine is a DELL

Thank you all for your help.
Unfortunately I am no further forward.
I have tried the following this
afternoon:
(1) Trying the DirectX
version on the NT4 machine. This crashed in flames
very quickly. I tried
to update the DirectX driver. I looked at the
Microsoft web site, saw
the blurb for DirectX 8.0a and searched it for any
mention of NT4.
Eventually I found the page which as explained in earlier:
J3D requires
DirectX 7+; NT4 offers DX3.0a but only on NT4 SP6+ and the
machine I was
on only had SP5. Well and truly hammered!
(2) I decided to move back to
OpenGL, but upgrade to the new version. I
carefully uninstalled the J3D
openGL 1.1 stuff on the target and development
machines, and installed
1.2.1 J3D openGL - slightly tricky because from this
morning I am
running DirectX and OpenGL development on the same machine. I
tried the
software on the new machine and it failed. Moving to a new version
of
J3D will mean I will have to tweak my installation procedure again, and
leave me with users running different software.
(3) There was still
the hardware acceleration that John said I should turn
off. I looked in
the obvious places for the HA option but could not find it.
I phoned the
company helpdesk and after a very long time they got back to me
and said
that NT4 does not have HA!
(4) Upgrade the drivers: unfortunately the
company's main gateway site was
down and by that time I was running out
of time and ideas.
Regards
Mike

Java 3d
Lee, I think deployment is going to continue to plague us until Java can
update itself nearly automatic and painless. I may be wrong but I
get
the impression Java 3D is more prone to quirks in video drivers than
other software (but this may just be that other companies do more
testing and code around driver quirks... something we can't really do
effectively in Java 3D). I'd like to hear a comment from one of
the Sun
Engineer's to know to what level are they working directly with
NVidia,
ATI, Matrox, etc to understand and debug these issues.
How does Sun profit from Java 3D? The same way they do with the
rest of
Java. Book sales, support services and good public
relations (Java is
responsible for a lot of people having even heard of
Sun). I'm
surprised Sun hasn't been more aggressive at self
publishing Java 3D
documentation books.
