I was wondering if J3D was capable of bump mapping (in browsing the
archives, I saw hints that bump, normal and reflection mapping was
possible, but no instructions on how to actually do this).
Is this possible?

Hi Mark,
Bump mapping can be acheived using DOT3 texture combine mode, but
unfortunately there is a bug with multi-layer texturing that I haven't
been able to circumvent yet, so you can't bumpmap something that already
has a texture on it. Hopefully when the source is released we can fix
this

Fair enough. What about normal mapping (ie, an RGB image where pixels
represent a normal vector at a a given texture coordinate)? This
strikes me as an extremely useful feature which is starting to get wide
usage.
Ah yes, this is in fact what I am describing. The program is fed a
graphic where

Hi,
I have a running demo of DOT3 Mapping here:
http://planeta.terra.com.br/educacao/alessandroborges/java3d.html
To have it working you must have a Dot3 capable video
card and at least 2 texture pipelines.
Anything equals or better than a GForce2 MX or Radeon
