Ok I think this an depth test problem. The alpha is showing through the
terrain if it is folded as if the depth check is disabled.
It should be :
glEnable( GL_DEPTH_TEST );
glDepthFunc( GL_LEQUAL );
Is this how decals are implemented?

As Doug has said, this looks like a bug in Java3D. However, I'm going to
challenge the basic assumption that you need coplanar surfaces in order

Hello,
Does Java3D allow a programmer to add new rendering capabilities? What
we want to do is to add the capability of concave reflection for objects
(The goal is to render a mirror dome). Is this possible to do with
Java3D? Or is the rendering something the Java3D has no control over?
Thank you

Define 'non-square' ??

That's why you have a unit cube. There's an unfortun

I tried to use the ViewFrustum class from org. j3d. The view frustum after

Hi!
I'm newbie here. I need to make a scientific project in school (i'm a secondary

i will make my own 3D game, but i have to write some theory about Java 3D game

GB,
Persistence is a characteristic of the phospor used in the monitor; black is
merely the absence of excitation and will have no effect on persistence.
The only way to change the persistence is to change the phosphor.

Hi Ajax,
I don't know whether is this what you are trying to
do but try inserting these lines into your code.
TexCoordGeneration tcg = new
TexCoordGeneration(TexCoordGeneration.SPHERE_MAP,
TexCoordGeneration.TEXTURE_COORDINATE_2);
app.setTexCoordGeneration(tcg);
Hope it helps.

You
obviously need good Java. A lot of patience and a hard head ( you're almost
guaranteed to spend a lot of time beating it against a wall at first) are
useful.
The

I need to display QuadArray in 3 modes:

I know how to implement first two modes.

Kelvin, Kyle, Michael,
Thank you all for the feedback on this problem. The problem did indeed
exist for 'ogl_install_check' as well, and Kelvin's 'gamma correction'
suggestion fixed the problem very nicely. The gamma value of 1.0 giving
me a close match to what I see on my PC, and also to what I

Alex, I tried
what you have suggested. It works to some extent ie. the texture was loaded but
only a part of it. For eg suppose there is a jpg with three vertical strips with
colors red/white/blue, and if I texture map this jgp on a sphere with
radius as per cmds given by you,

The attached are programs for rendering an image to one eye only. What I am
going to render is a green drifting grating to left (or right) eye. Because
of the long persistance of the monitor, the other eye (the eye which should
not view the image) will also view a faded image. That
