I have several small spheres, red and blue, around (0, 0, 0). When
I
start my app, I set the viewing platform to be at (0, 0, 25). I see the
spheres.
I coded a behavior to zoom in on the spheres by changing the viewplatform
location from (0, 0, 25) to (0, 0, 24).
As soon as I type the key to invoke is zoom behavior, I loose sight of all
the
spheres.
In my behavior I use
vEye.set(x, y, z);
vCenter.set(0.0, 0.0, 0.0);
vUp.set(0.0, 1.0, 0.0);
T3D.lookAt(vEye, vCenter, vUp);
targetTG.setTransform(T3D);
to change the view platform's location and orientation.
x = 0, y = 0, z = +24.
And looking at (0,0,0), I should see the red and blue spheres.
targetTG was obtained by
SU.getViewingPlatform().getViewPlatformTransform();
Now, the real strange thing is....
If I set the Eye to (x, y, -z) I *do* see the spheres, but they are all very
dark gray.
But they do appear.
Does anyone see what's wrong here? Does anyone have an example of using
lookAt()?
