Hi All,
I have a Window 2000 Pro installation that was running OpenGL successfully under a Java3D \ VisAd application just days ago. Because of some problems in the operating system (Windows Explorer generated errors on launch), I have reinstalled the OS onto the harddrive, overwriting the original system, but leaving all user directories as they were. At that time, I had already installed:
java3d-1_3_1-beta-windows-i586-opengl-sdk.exe
and, as mentioned, it had been running great!
On the very next launch of the VisAd tutorial file, P_01_2.java attached, the following error launched a modal dialog box with the title:
nVidia OpenGL Driver
and the message:
Driver components mis-match. Exit is the only option.
and an Ok button. The app did not show anything on screen aside from this, but I’ve been able to debug it to line 67, which is:
display = new DisplayImplJ3D(“display1”);
I have a Riva TNT card and 512Mb of RAM. I’ve tried reinstalling the above mentioned OpenGL executable, and have tried uninstalling that one, and then reinstalling:
java3d-1_3_1-beta-windows-i586-directx-sdk.exe
which is the alternative for Java3D, rebooting, etc.; however, nothing seems to work to clear this error. The price for this experience continues to grow, as I find no mention of this error anywhere on Sun’s site, or on the Internet in general (searched using the quoted error string on dogpile.com). Any suggestions would be appreciated.
Thank you,
Evan
P.S. I’ve attached the file P1_01_1.java, a similar 2D representation of a similar problem that does execute correctly for your comparison.
BTW, VisAd is one fantastic package, for those of you that do numerical programming!
