I am new to Java 3D. Just getting started actually.
Here is my question: How useful is OpenGL topics
and documentation, and/or general 3D topics when using
Java 3D? Meaning, can I take articles that cover 3D topics
in C/C++ using OpenGL, and implement them using Java 3D
or does the J3D API not
Using Java3D API the answer is negative,
but you can do that in two manners:
a) Throwing a vertical picking ray to the terrain, and getting the
intersection point.
b) By an auxiliar data struct: double[][] of heights. You must make a
method which accept a point (x,y)
and returns the he

some other product is better than Java3d is humorous.

According to your TransparencyAttributes your doing additive transparency.
Which means if you have 2 gray polys (50% intensity) overlapping each other,
where they overlap they will be added together when rendered to the screen

Hello,
Does anyone know a solution or workaround for the problem where obscured
transparent objects appear much too bright?
I'm displaying stereo images for viewing with 3D glasses. I use the following
appearance code:
ap2.setMaterial(new Material(red, black, red, black, 1.0f));
No you cannot apply different textures to the shape except with
multi-tetxuring, and that won't help your issue.
Your options are:
1. Do a an ordered group with by-ref geometry and blend multiple passes into
the same geometry. You might be able to use a decal group here. Do polygon

That blending method is one commonly used for particle systems and has a
multiplicative effect on any alphas which are blended. That's probably not
the one that you want. I think the default created by new
TransparancyAttributes() is the one you want.

This may be caused by the front clipping plane of the viewing frustrum. If your object
or parts of your object are in front of this plane it gets completely or partially
clipped. There is a default setting how far the front clipping plane is from the
"camera"
but you can change this value.

I'd say it really depends on the topic. There is a number of general 3d
topics that could be used in Java3D. Although you will need a lot less of
these when dealing with Java3D, some of them will probably low level or more

And for me in particula
I'd like to say that I also feel that sending non-English emails to this

Yes, perhaps those who wish can request that Sun starts another email

Sure.
I had a look to Anfy3D "API" but it was a little bit poor.
Perhaps it is enough for 3D presentations in web design, a 3D brother for

There are a few possibilities:

planes.
2) You've moved to a position where you

You'll have to start a new strip. You can secify the length of the
individual strips by using the stripVertexCount parameter.
