Shawn:
The detail texture is the same across rocks and
grass. The main texture is generated by blending 2 or more textures at
each texel based on certain criteria. The most common criteria I use is to
blend each texel based on the texel normal in relation to a normal perpendicular

What this bug refers to is let's say 4 texture units have been defined, but
only two of them are enabled, and let's say the hardware supports only
two texture units; in java3d1.2.1beta1, we onl
David,
Bug# 4392047 has been filed for this bug. In the meantime,
you can pass the texture coordinate as float. This should work.
float texCoord[] = {texX, texZ};

Just a clarification...
This bug is fixed in the sense that the geometry primitives have been
optimized in 1.2.1 beta2. For the Box primitive this means the internal
TransformGroups have been removed and geometry is cached so boxes with
the same parameters can share their geometry. These optimi

Great looking snapshot! I have two questions for ya.
1) Is the detail texture on the rocks and the ground the same? It looks
like it but not quite sure - didn't see any seams though so it must be

Hi,
my Java3D-Program I wrote at the university does not run with my
home-PC. I don't need any high-performance there, I just need to take
screenshots to picture my diploma with examples.
I remember some command line switch to enable emulation or something? Or
shall I try a new driver version? T
I am using IndexedLineArray.setCoordRefDouble(), but only one or two lines
get rendered when I am specifying hundreds or thousands of lines.
If I copy each of my double coordinates from the same geometry (casting)
into a float array and call setCoordRefFloat() everything seems to work
fine.

You're welcome. A small correction: the length of the cross product of two
edges of a triangle is twice the area of the triangle, not half as I wrote.

I got multi-texture working. Looks like using
the methods to set a single vertex are not working with multiple sets. I
just changed it to build the array of floats then set them all at once.
That worked perfectly. I have it working in OpenGL on a NVidia TNT ultra
card using j3d 1.2.1 bet

We are doing this right now, the "detail" use of

has some problems on hardware accelerated multi-texture cards, aka the GeForce.
We have only tried no more than 2 textures at once however

I have worked with multi-texture quite a bit now
and I have run into many, many problems. However, all but one were in our
code. It's just gets confusing very quick!
I'd like to see the entire exception dump. Check like crazy (as if you didn't!)
and if it won't come clean. If not, "whip" up

Hi,
This bug
4346786 - OutOfMemory error when generating 20,000 Box primitives
is fixed in next v1.2.1beta2 release. The Transform3D group in
the utility Box/Cone/Cylinder primitives is removed.
Thanks.

I put my vertex coordinates into a GeometryInfo object. You don't need any
transforms to do it that way. The tutorial has a chapter that focuses
mainly on this subject.

Sorry for the words I used. I was just a bit too disappointed then.
Can you show me how you managed to construct that large number of polygons?
Did you use an individual transformgroup for each object?

Thanks for this valuable information.
The area weighting scheme, where un-normalized cross-products are summed, is
real slick.
And faster than the un-weighted approach.

Hi all.
I use BoundingSphere.getRadius() as a part of my code to fit a scene within

On our IBM NetVista machines this call returns -1.0, all other machines and

My project involves drawing over 25000 polygons, each as individual objects

don't be disappointed and just skip those transforms by building

Hi all,
I have a major problem with picking. I only can pick an object when i'm
inside it. So, i zoom in until i'm in the object. I only set the
transformationgroup of the object to setpickable(true).
This is what i do :
tg_scale = new TransformGroup();
tg_scale.setCapability(TransformG
i have the same question and if I draw 1 boxes,it is out of memory.
I don't know why,can someone give us a good resolvtion.
