Hi Felix-

Hi there

if i try to run the P4_01 example from Ugo Taddei's Tutorial i always
get the error below.

Any ideas what is wrong or hints where to look closer?

We ran into this with the last IDV release.  The problem is that the
version of Java 3D that you are using (1.4.0) requires GLX 1.3.
This change was made with the release of 1.3.2.  At least with 1.4.0,
they have a nice error message explaining the problem (see below).

You options are to upgrade the GLX on your system (what platform
are you using) to one that is 1.3 or higher, or to back out
and use a version of Java 3D that is less than 1.3.2.

Don

Thanks in advance.

Java 3D WARNING : reported GLX version = 1.2
    GLX version 1.3 or higher is required
    The reported version number may be incorrect.  There is a known
    ATI driver bug in glXQueryVersion that incorrectly reports the GLX
    version as 1.2 when it really is 1.3, so Java 3D will attempt to
    run anyway.
