Hi, does anyone have 3D modeling program that is
done by Java3D? Since I wanna make a modeling application and try to save
it into a format, then I will create a 3D game with my friend later. But
what I need is about the 3D modeling tutorials. Any clues?
Thanks.

sorry abt that. what i was aiming to do is to create a shape,
say a sphere on the space where the mouse was clicked. the
z-coor will be fixed so the only problem is to get the
corresponding x,y coor of the point on the vworld where i
clicked the mouse. the Example3.java shows me where the points

Hi Friends:
The attached is a demo which shows the problem I have
met recently. I render two geometries to left / right
eyes separately. To get things simplified, in this
demo I used two ColorCubes (different size).
However, when the program is running, only the first
ColorCube can be seen. Th
hi David,
If possible even i would be intrested to have a look at the packages..it
would be great help, spl we could get to have alok at their design. Even
we are developing a 3d lib, building upon a 2d lib. in c. we have just
started. I am looking for some info on the design issues would be of

Hi,
Just started.
I tried jdk1.4.0 and java 3d today. Windows 2000 tells me "Fail to create
back buffer -DDERR_INALIDPARAMs"
Who knows what it is?
Thanks

No. If setVisibile is false, the geometry will not be sent to
OpenGL/DirectX.

Take the top node for the man and get the TransformGroup's Transform3d.
Let's call it t3d.
Now
Vector3d position = new Vector3d();
t3d.get(position);
should put the position in the x, y and z fields of position.
Keeping the man inside needs collision detection, or better, collis
What if you want to reconnect the Shape3D later, or move it to another part
of the SG? In that case, you've got to have the BranchGroup structure,
can't just remove a child - as I know to my cost!

Hi,
If the purpose in removing the Shape3Ds is to prevent them from being rendered
you could use RenderingAttributes.setVisible or a switch node. All the Shape3Ds
will still be in memory but only selected ones will be rendered.
Hope this helps,
Renoir

Oooh... bad word alert!
Hehe... yes, the limitation of only being able to add or remove branch
groups at runtime is a painful one. I can only assume that this limitation
buys Java3d the power to more efficiently manage the scene.

Hello,
There is no way to remove a Shape3D from the live scenegraph unless the
parent of the Shape3D is a BranchGroup which then can be detached from
its parent. That is:
TransformGroup
-Shape3D
You cannot remove Shape3D from live scene but
TransformGroup
-BranchGroup
-Shape3D
