Hi,
sorry this question is off topic and not related to Java3D.
I am working under Solaris in a tcshell and tried to expand my
classpath. Okay it is very long about 12 lines and now the shell states
"word too long" during source .tcshrc. Is there a limitation for the
length of the classpath varia

Most shells have a limit of 1024 characters. The real question is why on

Because to nominate a JAR file to be included in the classpath you must
point at the file explicitly. You cannot just point the classpath at the
directory and have the JVM auto

Hi All,
I am working around the following bug message:
class can't be instantiated.
java.lang.InstantiationException:
at java.lang.Class.newInstance0(Native Method)

Hi Desiree,
Well... probably you could reduce the number of jar files
by re-archiving the source files ?

I'm not sure that would work because at the point the variable is
expanded (for example 'echo $CLASSPATH') it will expan

Hi,
the construction of the classpath looks like this now, I tried some of
your suggests:
setenv CLASSPATH .
#setenv GISTERM /net/ipfy/hilbring/PRJ/GIS/GISterm
setenv GISTERM /net/ipfy/hilbring/GISterm
setenv GISLIB ${GISTERM}/lib
setenv UISLIB /net/ipfy/hilbring/uisjars
setenv CLA
You can expand environment space in Windows by running "command.com /e:4096"
if you want to set systen environment to 4K. I can't remember how to do it in
Linux, sorry.

hi there again,
has anyone of you guys implemented a Thread that watches the state
of the live scene graph? this Thread specifically watches which of the
objects in the live scene have changed their Geometry and Appearance
components, and then performs a certain action.

Hello,

two java3D versions in terms of specular shines (loading same model under

Ah, sorry.
Use an OrientedShape3D.
One caveat: I seem to remember mentions of problems w/ OrientedShape3D

it does turn out to be a problem, you can also look at the Billboard

We've been trying to resolve this issue for a while now(See Java bug

Thank You John, that was a great hint. It took me all day but I figured it out. Without you and the JAVA3D mailing-list I would had not been able to figure this out. Man do I like JAVA3D! Michael Carter Purdue University Student - Original Message - From: John Wright Sent: Thursday,
Your app works just like it is suppose to in Java3D. The viewer is not
always along the Z axis of an object. Think of it as having a universal
coordinate system and the objects and viewplatform are relative to
that. When you move or rotate and object, it is relative to the universal
coordinates
