Yow! Talk about convoluted interactions. I figured out what the
problem is (kind of)...
Lets start from the present and work back in time.
1) Transparency is a bit schizophrenic. When a shape is made
transparent and that shape involves a texture with transparency the
spec is somewhat unclear
possibly a bug in the texture loader? i am using:
TextureLoader(java.lang.String fname, java.awt.Component observer)
- and -
TextureLoader(java.lang.String fname, java.lang.String format,
java.awt.Component observer)
and have no problems loading my local textures...
maybe you could try using these
have a look at how Text2D works... i adapted that class to a Mask2D class,
which does the same, except it doesn't draw text, but an image i passed...
what you get is good for a static transparent dashboard which you could add
to the root node of your branchgroup (either z-buffer disabled or move i

Hello Justin,
many thanks for the source-code you posted to the Java3d-mailinglist
concerning my problem "how to click an object". It seems to be exact
the code i need.
In the first line of your source-code you write
"public class MouseSelectBehaviour extends MouseClickBehaviour"
Well, i can n

Another question. Sorry, but I am not as familiar with 3d grahics as
I should be:
First, what I try to do:
I have two points p1 and p2. I want to draw a 3d arrow from p1 to
p2. My current solution is to compute the three rotations (x,y,z)
seperately and to rotate the arrow like this

i am a beginner. i want to ask how to use the htmlconvert.
After i decompress it,there is no executable file.So how to call the
program to change the html file?Also, i just set up the enviroment, how can
i test my enviroment can see java3d or not?any web site?

This is the most comprehensive one with a whole bunch of useful

I have written a program that creates a branchgroup attatches it to a
scene displays it and then records the time it takes a user to hit a key.
The process repeats 42 times. On my pII 300 with 128 megs Ram it gives
fastest reaction times of about 300-500 milliseconds which is reasonable.

Decimating the triangle set can be done in a manner analogous to the
technique used for determining the best points for drawing a set of lines
that approximate a spline curve. Once you get your set of triangles via
Delauney or some other algorithm, you locate all of the vertices that are

You might want to look at the java.awt.geom

My venture into transparency, texturing, and overlap is coming to a
close. Here are a few additional observations to those from my post
yesterday...
These observations are made using transparent shapes with a
transparent texture. I haven't had time to try other combinations and
permutations and
Make sure u installed both Plug-in and Java3D library. Don't forget to
move (or copy) all your files from jre\lib\ext directory up one level if
u r running Windows system.

Don't forget to convert .html files coming in the package. As to texture
sample, u wouldn't be able to run it in browser unless appropriate
security policies are set in java.policy file (u need to allow the
applet to access your file system). The deal here is that in those
