Hi All,
Actually, all I want to do is to add a translucent JTextArea onto the
Canvas3D. I need the Canvas3D to be the background for this JTextArea. Is
there any alternatives for me to achieve this?
Thanks in Advance.

First, use textures with transparent
backgrounds, and make sure their boundary pixels are
transparent.
Second, use DECAL texture mode.
Now, for each texture, supply the geometry
with texture coordinates that stretch the
text
You can also use the Switch class. I tried the setVisible() and it was
too slow (I can see each object being turned off and on). With the Switch
class, it is fast and all objects disappear at once (those that should
disappear, of course) and appear at once.

Rong,
Sounds like a good idea. I think I can construct a Bounds object of BoundingPolytope
by 5 planes, which can be used to define a PickBound.
Then, I'll create an instance of PickTool and set its pickShape to the
PickBounds created above. (I guess we can't set a random pickShape used by

Hi,
I agree with Peter.
As a general rule, avoid "mixing" GUI components
and graphics by placing them in different JPanels (or subclasses of it).
This minimizes chances of GUI components and/or graphics not displaying
properly.

Alejandro

As I am aware; but how do I send my changed raster back to the canvas? I
don't see a way.
Perhaps I need to just use offscreen buffers and paint the raster to the
canvas within paint() ? There has to be a better way

Hi again,
After installing Java3d v1.3 (from Java3d 1.3 beta), the problem of
rendering incorrect slices went away.
However, my images are still incorrect:

Can someone give me a hint as to what maybe wrong?
Thanks!

Hi,
Try the following step
1. After you get the four points corresponded the mouse drag,
build a cubic bound using the code for class PickObject for the pick
aperture in SUN j3d Picking utility package.
2. create a instance of PickCanvas, and set the pickShape to the bound
which you created
Hi All,
can someone give me a work example of the GeometryArray Method.

Hello Fernando,
I don't have much time now but for the first peek i would say the
problem is that you put all the named objects into ONE branchgroup,
and then you manipulate that branchgroup, and this way of course
everything is moved at once.
If you want to treat the objects separately, modify
Ok ! Here is what I know about rendering transparent geometries...
If this probably confuses rather than clarifies the issues, y'all
be my guests and make the corrections...
Opaque/transparent geometries under an OrderedGroup are rendered
before transparent geometries not under an OrderedGroup. So
Hi,
You can subdivide the object in several parts.
Then you apply separate texture on object part
that you want.
Then you have one big object with several textures...

does somebody know how to put a texture on an

Hi.
I think I may have seen this problem too. I made a test case but I was debating
whether I should post it, but now I can't resist since it seems like the same

It's two Text2D objects under an OrderedGroup. If you drag the mouse to spin the
one labeled "FAR" in front of the one labeled
Without actually running the thing the only bit I'm not sure about is the bounds on
your TG's mouse behaviours (I presume that's how you are 'moving' the objects). The
bounds all appear to be the same and are I think the same as the global bounds of your
scene. If that is so you will always act

Are you sure you need to add it on the *Canvas3D*?
Wouldn't be sufficient to add it below/over/r

Is it possible to add a swing component, say a
JTextArea onto a Canvas3D? If its possible, how do I go about adding
them?
Thanks in advance.
