[Source] NPE fix proposal

[Norbraten, Terry (CIV)]

Nope, not using apps/replica, though we should.

He's using the browser app with the following switch: -captureViewpoints

<java classname="xj3d.browser.Xj3DBrowser" fork="${fork}" dir=".">
  <classpath>
    <pathelement path="${classpath}"/>
    <fileset refid="xj3d.jars.all"/>
  </classpath>
  <!-- -Djava.library.path needs to point to jogl.dll driver -->
  <jvmarg 
value="-Djava.library.path=${xj3d.dir}/../${native.library.path}"/>
  <arg value="-captureViewpoints"/>
  <arg value="${relative.path1}/${relative.path2}/${name.short}.x3d"/>
                        </java>
