Thanks for the test program and the image. However, when
I run your test program I don't get the white border
shown in your image. For me, the image is quite similar
with or without texture mapping. I'm running JDK 1.4.1_01
and Java3D 1.3.1 on Sparc Solaris. Maybe someone else can
try?

Cheers,
Bill
