Re: [JAVA3D] NT4 and Java 3d

[Josh Richmond]

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 Precision 420, dual PIII-933, Elsa II   josh   ---------------------------------------------------- Joshua L.

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.

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. - John Wright Starfire Research "J.
