Title: Network Blitz
Hi Friends:
When I use MainFrame, I have to pass an object of Applet to it. Is
there any other file which has a similar function but can let the JWindow
passed? For example:
when I use:
new MainFrame(new
BasicRecipe(),sreenSize.width, screenSize.height-10);
Hi,
If you keep a referance to your original coord array then you can simply change the
values in that array directly in the
updateData() method. It goes something like the 'kinda-code' snippet below. If you use
BY_REF correctly you shouldn't need to
set anything other than the values in your or
Hi,
After an intermittent 12-hr period I finally decided
to put the monkey-typewriter-shakesphere theory to
test and came up with a remedial solution, that is
line.updateData( new GeometryUpdater() {
public void updateData(Geometry g) {
g = shape3D.getGeometry();
LineArray tempLine = (L
Why does GMatrix give a MismatchedSizeException when a multiplication requires the
size of original matrix (number of columns) to changed?
Example:
GMatrix test = new GMatrix (5, 2);
for (int i=0; i<5; i++)
for (int j=0; j<2; j++)
test.setElement(i, j, i*5+j);

Hi,
No, BranchGroup does not extend OrderedGroup, it extends Group.
Both OrderedGroup and BranchGroup are subclasses of Group class.
And ALLOW_CHILD_INDEX_ORDER_READ is a field of OrderedGroup, not Group.
So, you should change the below to
scene.setCapability(OrderedGroup.ALLOW_CHILD_IN
Dear all:
i thought a branch group extends OrderedGroup. so why am i getting an error
like

scene.setCapability(BranchGroup.ALLOW_CHILD_INDEX_ORDER_READ);

Thanks Kelvin. Much appreciated. Here's another one...

Since 1.3, that is false. See ImageComponent2D.setSubImage(). That works wonderfully.
Thanks for spotting

Well, reason is quite simple. Default geometry generated by Sphere
contains {0} map for tex coords. You need {0,0} map - for both texture
units.

I would also suggest using OptimizeIt to see where your memory resources are going.
Very handy application that lets one see total number of objects allocated, percent
time spent in subroutines, and an allocation table to see when objects are being
allocated.

Hmmm...interesting.
What I'm hearing is that it would be really cool if the XJ3D package could be
configured to work just as a loader of models (with none of the
event/interactivity stuff). That way, I would think you could get much more
efficient models because they could be optimized. You woul
Well, the answer for your case it's quite simple. Create all the balls,
behaviors and the other scene elements right from the beginning, then you
don't create any scene element, only modify paths and visibility. I would
make on top of all the balls a switch, so I would turn the balls on or off

Yes, you can use the system monitor. If you see that when loading the scene

over and the memory increases another 10 mb, and each time you repeat the

If the grid of vertexes is regular (x point by y points of constant
separation), Delaunay triangulation would not be needed, and is 1000x less
efficient than a regular grid triangulator that I have.
So i presume something must be wrong with the implementation.
