You're seeing blue and red in the bump mapping?! I think you've got
other problems! If you are seeing that, then you don't have texture

Hi,
I tried this approach, but still the color change updations are not taking
place as expected. The following is the sequence of operations.
In application class (GUI).
1. Change background color of Canvas3d (from black to white).
2. Set flag to false. (Canvas3D preRender check flag).

Hi,
I use j3d in a servlet that produces an image. Every
time the servlet is envoked, I create a Universe stick
a few objects into it, render to an offscreen canvas
and I get my BufferedImage.
The problem is that it works (and works great!) only
the first time around! It *always* fails the second
Thanks for this information. I must have skipped over it when I read
through the docs earlier. I will investigate this more and see if a
solution lies here.

You are at a dead end with that aproach. You cannot bypass the constructor.
There may be a solution using replacement objects. Except from
Externalizable API docs:
"An Externalizable instance can designate a substitution object via the
writeReplace and readResolve methods documented in the Serial
Thanks for the response. However, to construct a geometry array, one of
the parameters that must be passed is the vertex count, which is simply an
integer. If you pass 0 as the vertex count, then I have not been able to
later increase this vertex count which has been the problem here. Any
ideas

Hello,
Does anybody of you know an algorithm to find the largest area rectangle

Alternatively I could use a check that could say if a rectangle of a

The polygon doesn't contain holes, but it can be concave.

adding and removing the geometries from the Shape3D, you do not need to detach
the parent BG. Only thing you have to take is that the geometries which you are
adding into the shape are of same type.

Hi folks,
I have created an application that imports 3D geometry and then creates are representation of that data on the canvas 3D. How can I import different geometry whilst the scene graph is live, do I need to detach the BranchGroup first or what?
Any ideas guys?

The point is after you change color of a
geometry array in the scene graph, make sure that preRender() is getting called,
before you do what you are doing in the postSwap().
Now preRender(), postSwap() etc gets called
automatically by the j3d renderer thread and you shoould not call them

Hi,
Thanks for the reply. Actually what i meant by frame delay is that we are
incrementing a counter in preRender and dumping the JPEG after that in postSwap
instead of postRender. Below is the section of the preRender code.

Hi,
I want to know how to ensure Scenegraph updations get reflected in

Hi Nick,
Not sure if this is what you're looking for, but in cases I don't know the
size of the array beforehand, I do the following:
At initialization (so, before the first constructor) I declare:
float cords[];
And inside the constructor, just before the GeometryArray, when the number
