Hi
all,
We
use the Transform3D method lookAt(Point3d eye, Point3d center, Vector3d up)
to move the ViewingPlatform such that we can fly our world scene. Currently our
viewing defaults to the perspective projection (lookAt(...) produces this). We
would like to also view the scene in the paralle
I'm still stuck on this problem:
If I have TransformGroup transG in my scenegraph subject and an OrbitBehaviour on my
ViewPlatform and I need to move a second transformgroup transG2 based on the
relationship between transG and the ViewPlatform, moving it appropriately when either
of these moves
I have a sphere in my scene. I put a point light in the center of the
sphere. I want to move the sphere/pointlight (a glowing orb) around in the
scene.
Since light positions don't change when a transformgroup's transform
(location) is changed, how do I keep the light within the sphere as the

What do you mean lights dont change when you move their transformgroup?
Pointlights certainly do, I'm not sure about other types.

Well, I just tried it again and your right.
I don't know what I was doing wrong yesterday
Sorry. Forget last e-mail note.
Thanks,

Hi All,
I attached a simple program of picking multiple objects by dragging mouse to
draw a window on the screen. This program draws 2 polygons. If my window is near or
enclosing the right common point of the 2 polygons, it works fine.
Otherwise, it can't get the right result.
The picking proces
Ben,
Here's how I would handle it.
As you know, any time your view platform or scenegraph subject moves, a
redraw is automatically triggered. So, have your behavior wake up on
WakeupOnElapsedFrames( 0, true ), check the Transform3Ds in question and if
they've changed do what you need to do.

The program works fine with this set of shape, but why it doesn't work for
the previous case??? Does any one have a clue? ---white

I find that the mnemonics work when I use HelloUniverse

Any hints will
Hello,
Currently we are working on a program that runs concurently with other
3D/OpenGl applications. We are running in passive mode and most of our
behaviors are being executed every frame. For the most part everything
appears to be working fine, however if we run the program on a Windows

the text is textured to the metaball, but there is also a reflection of the text is
also textured. I use OBJECT_LINEAR. I can't f
