hi all
I would try to make a progarm that is user interactive 3D
avatar animaion.
first, In interactive part I would use Behavior
class. For detail, I would use Behavior class with WakeUpAWTEvent to
catch key pressed event
That key pressed event is specific key like, 'A'
Hi Georg,
I usually make my appearance this way :
//--
public Appearance buildAppearance( )
{
Appearance appear = new Appearance( );
ColoringAttributes colorAttrib =
new ColoringAttributes(0.0f, 0.0f, 0.0f, 3);
Color3f matAmbient
Hi ,
This is just a announce about some improvements over

Not
sure if you want a behavior capturing keystrokes, that's something you pretty
much want instant and 100% available. That's my two cents--if somebody has
a better method, lets hear it (always looking for the *right* way to do
things)
I
attached a KeyListener to the 3D canvas, subclass
You cannot have two texture unit states set for one shape and apply
different ones to different parts of the same geometry. In other words, you
are always applying all the texture units specified in the tex coord set map
to all the triangles in a geometry array in a shape.
The closest you could
This looks like a bug in that version of Appearance.setTextureUnitState().
Use the array version of Appearance.setTextureUnitState() as a workaround.

Georg,
The NullPointerException is expected because the texture unit state array
of the specified Appearance is null. This version of the setTextureUnitState
is to modify an existing entry of the texture unit state array of
the Appearance. So for the first set, use the array version of
setTex
After refreshing my memory by reading the spec, I am going to
change my answer. :^) The setTextureUnitState(int, TextureUnitState)
form may only be used once the length of the TextureUnitState array
has been established. The length of that array is established with the
setTextureUnitState(Textur
Hehe, that was fun :)
But if you look at what he is trying to do here... it looks like he wants to
have one texture which is the roof and one which is the facade and apply
them in the same shape. I think it can be done if each piece is in a
separate geometry if the tex coord set map defined them
Hi group,
thanks to all, who answered.

Oops, my fault, next time I'll read the docs carefully.

I think that problem lies in other place. I suppose that when there is
no rotation interpolator, realtime refresh does not occur at all. It
happens only on forced repaint/view transform, because nothing in scene

What is the best modeling program for me to use if I
just want to make some simple models (no textures or
lights required) for use in java3D. I assume I want
.obj or .vrml files, and I don't want to pay for fancy
features I won't need.
Thanks

Hi Artur,

It was just a test, inspired by the recent discussion about
100.000 Spheres, where I got the impression, that Shape3D's
introduce considerable overhead. There i.e. was a suggestion
to reuse significant amounts of Geometry under
Hi Simeon,

Because I can't find back that reference: I'm clueless, I just
remember that issue to be mentioned. Yes, it seems questionable,
I expect SUN to do it the right way.
Have you seen Fred Klingener's post? His approach
