[JAVA3D] Zooming on Scene
Hello all,
I have used KeyPressed event to zoom on the scene. My Scene is on X-Y axis.
To view the scene from front side, I have rotate the camera on x-axis.
Now to zoom the scene, I should decrease the y-axis.
When I run the program, for the first time that I press z-key it zooms, but to continue it, camera position changes on y-axis. I have attached the code of my camera.
Can you find what is the problem ?
Thanks in advance.

[JAVA3D] Smooth movement by PositionInterpolation
Hi all, I have added some objects as below to a BranchGroup: BG | / / / TG / / TG2 ( ALLOW_WRITE ) / / Object I have passed the TG2 as parameter to the PositionInterpolator. I set the Transform3D of the second TransformGroup ( TG2 ) every second. But the movement is jerky and it jumps between positions. Another problem is position.

I have added Some objects and an PositionInterpolator for each to a TransformGroup.

Re: [JAVA3D] Memory problem
Hello ,
I am working with IntellijIDEA, and I increased the heap size to 512MB. So now it works for 180 objects but not for 200 objects!!!
And another question: Is it possible to load a vrml object and then clone this object.I have added below my source where I load objects :
BranchGroup bg=new vrmlLoad("03.wrl");
transformgroup.addChild( bg );
bgRoot.addChild( transforngroup );
This loading repeats for 200 objects.

[JAVA3D] Problem with Coordinates
Hi,
I want to darw two squares, using TriangleStripArray, I use the constructor below :
TriangleStripArray geometry = new TriangleStripArray(6, TriangleStripArray.COORDINATES, new int[] {3,3});
Point3d[] points = new Point3d[] { new Point3d(0.5, 0, 0),new Point3d(.5, .5, 0), new Point3d(0, 0, 0), new Point3d(0, .5, 0), new Point3d(-.5, -.5, 0),new Point3d(-.5, 0, 0), };
1- Do I need to set 8 points or 6 points ?
2- How should be the order of the vertexes for each strip ? ( clockwise or counter_clockwise )
Regards,
Saeed

I want to draw a Quad using two TriangleArray .I want to locate the Quad centrality ( 0, 0 , 0 ).
I used the code below :
Point3d[] coords = { new Point3d( 1.0, 0.0, 0.0 ), new Point3d( 0.0, 0.0, -1.0 )
new Point3d( -1.0, 0.0, 0.0 ) new Point3d( -1.0, 0.0, 0.0 ) new Point3d( 0.0, 0.0, 1.0 ) new Point3d( 1.0, 0.0, 0.0 ) }; Color3f[] colors = { new
Color3f(Color.white), new Color3f(Color.white), new Color3f(Color.white), new Color3f(Color.white), new Color3f(Color.white), new Color3f(Color.white) }; TransformGroup myTg=new TransformGroup(); Shape3D shape1=new Shape3D(); triangleArray.setColors(0,colors); triangleArray.setCoordinates(0,coords); shape1.setGeometry(triangleArray); myTg.addChild(shape1);
branchGroup.addChild(myTg);
But nothing appears on the screen.and when I change the Z_Axis' to Zero it works.
How can I do this ? and what is the problem with this coordinate ?
