I've been scratching my head over this one for
weeks now.
I want to be able to specify "roads" or "paths" in
my 3D engine with a series of 2D lines. That would give me the flexibility
to have roads any any angle, any direction, and any number/combination of
intersections.
There's two ways
Works perfectly. I almost have tears in my eyes looking at it now :). I
had everything pretty much the same, just I was DECAL'ing the texture onto
the shape, and I had screwed up the transparency attributes settings...
Many thanks,

Scott,
Pretty cool. I just downloaded and ran (no problems). With JDK 1.4 and J3D
B1 I was getting about 130 FPS, so you've got plenty of frames to spare!
One little bug I think I saw: the trees loose their vegetation when you get
*closer* to them. It looks like you might have a LOD calculation
First, use a PNG or GIF image with an alpha channel transparency for your
texture, I've had okay results with both. (Okay, GIF's don't really have an
alpha channel, don't flame me).
Then you have to set some attributes in the appearance and texture modes of
your 3D shape... here's the code I use,
Hi,
Does anyone have a small example of a program that places a transparent
texture onto an shape? I'm having issues similar to those mentioned on the
bug parade( the texture displays correctly, but the shape behind it comes
out black or white and sometimes other things, but never transparent).

This is true. The technique we have used is to take the regular elevation
grid and sub-divide in a 3:1 ratio. We use the AWT general path classes to
plot a bezier spline over the grid points, so in a 100 x 100 heightmap that
would create 200 splines. Thats 100 paths along the x axis and 100 path
I don't think DX8 has a reference or emulation mode, it was discontinued
after DX7.
IMO If you're using DX8 you're going to have to have 3D hardware
acceleration.

Smoothing the normals won't eliminate jaggies and sharp edges, it will only
smooth out your lighting.
You might want to look at creating some splines or bezier curves, and throw
a few more polygons into the mix.
But to answer your question directly, a quick and dirty method of normal

I am trying to create a surface with variations in elevation and layers of
soil. I would like to eliminate the sharp edges of the elevations and
make them appear smoother. Does anybody have any suggestions on how to do
this in Java 3D.

Translate to origin, rotate, then translate back.

I'd rather jump through a few hoops as a developer than to have to put

But now suppose you have several versions of j3d. How do you specify which version
of the jre uses which version of j3d ?

Excellent suggestion Alessandro, this would certainly help. I agree,
there should be a standard extensions directory that is JRE independent.

About Java3D x JRE Plug-In.
If we install a new release of JRE plug-in, we have our Java3D install
"missing" ,
since Java3D is installed in another sub-folder of another JRE...
Ex.:
day 1)
JRE 1.3.0 + Java3D(any version) Status = active
Java3D runs fine
day 2)
JRE 1.3.0 + Java3D (any) Status
ModelClip planes seems to loose their association with the transform of its
containing TransformGroup under some circumstances.
