Thank you John, I'd have to save some money to buy new hardware :)

Hi Ishwari
You may try that:
long bits=0;
for (int i=0; i<8; i++)
{
bits = (bits << 8) | getByte();
}
double value = Double.longBitsToDouble(bits);

Hi!
I'm doing some tasks with Java3D without too much knowledge about theory and
state of the art
of 3d graphics methodology.
I'd like to get advanced tutorials about 3d graphics on the Internet.
My main interest posts on:

Hi all !!
I'm currently testing PickRotateBehavior. It works fine with primitives and simple
Shape3D's (the object is rotated around its center). If I test it with a 3ds loaded
model, (made with different sub-objects), the objects rotate around another different
point (sometimes the origin).
Hi all !!
I have tested several file loaders, such OBJ loader from java3d API, Starfire 3ds
loader or VRML loader.
The problem I had before was to testing them from applets, because navigators don't
allow to read files from the local file system. Now the problem is solved, reading the

Hello,
i'm plannig to implement an 'realtime' oscilloscope for a simulation
engine.
Would it be a bad idea to use java3D for doing this?
Here, not the 3D features itself would be of interest, but the speed of
the graphics.
Assume e.g. a 1000 points timeseries ("amplitude", "temperature" etc.)

Hi all !!
I want to implement applets that display a file model (3ds model with sub-objects).
The Starfire 3ds loader builds an scene graph like this:

Hi Martin,
Thanks for ur reply. What I want is conversion for
an array of byte values not a single value.. is it possible?

Thanks Martin.. I understood the logic from ur
code. But this code is not working correctly. Like, for eg for a value of 4.0
the converted value is 2.0. I tried the sample in c++ and jave and found this
problem. The bits value is correct in both the cases. So the problem is only
because of l
I have not tried his code, but you should get a better idea looking at it
like this...
byte arr[8];
long bits=0;
double db;
for(i=0;i<8;i++)
arr[i] = getbyte();
for(i=0;i<8;i++)
bits = (bits << 8) | arr[i];
db = Double.longBitsToDouble(bits);
basicly convert the array of bytes to a si
Hi All,
I want to draw on the canvas certain entities like

a point on the screen, then select another point and then draw the line from the
The problem may be because its backwards. That is, it may be an issue of big
endian and little endian... I'm not sure if this will work... try reversing
the process and looking at the bits by using the function
Double.doubleToLongBits...
Also as a quicky you can try reversing the byte order dont
I am currently using OrbitBehavior to translate, scale and rotate the

A couple of comments:
1) You should be successful with Java3D but you will need to carefully
optimize performance.
2) Java2D would be a disaster as it is very slow compared to Java3D.
I will admit the possibility that some very clever programming MIGHT
give you adequate performance but I will say

Hi Raffi,
Current implementation will buffer the AWT event when behavior
disable to prevent any loss of events. Behavior disable can only
disable behavior scheduler to run user processStimulus().
To workaround this, you may want ignore part of the event

Hi Jyothi,
Which version of Java3D are you using (DirectX/OpenGL) ?
DirectX version have special challenge to implement Quad
in wireframe mode. It is because DirectX don't support
Quad at all. To simulate it, we break Quad into two triangles
and rendering it by building an index (so vertex w
Justin mentioned to me that someone posted a piece of code to compact a

the archives. Can someone send me a copy? I'd like to include it in
the Xj3D work as a useful utility for compacting a loaded scene.
