Re: [JAVA3D] Display problem using Java3D 1.3

[Raghavendra R]

Hi Kevin,

I tried setting the view transforms but couldn't resolve this issue.Will the Back / Front ratio affect display changes? My observations are that if i zoom out to quite a large extent the color change appears and on zooming in, the color change disappears and turns to the original color. Anything to do with clipping etc?

Thanks,
Raghav

Hi,

I am actually changing the Color of the Appearance Material of the
Shape3D containing the LineArray. How do i reset the view to the same
view after picking. The Picking process is transfered to my update( )
method wherein i am changing the color.

    

Transform3D view = new Transfom3D();
ViewingPlatform platform = universe.getViewingPlatform();
platform.getViewPlatformTransform().getTransform(view);
platform.getViewPlatformTransform().setTransform(view);

  

Also, how is it that the color change gets reflected when i zoom the
window?
    

When you change the zoom, you update the view, so the scene is redrawn
(and your changes take effect)

Note: I'm only guessing this might be your problem, it may be completly
wrong, but it might be worth trying to check.

  

Thanks,

Is your scene actually being refreshed after the pick? I'm not sure
changing the color of an entity will force a refresh?

Try resetting your view to the same view directly after your pick. This
should force a refresh.

Hi,

I have an application wherein i draw a set of lines (LineArray) in
Green color initially. Further, when i pick this line  and change its
color to Red, it doesnt get displayed in Red. Only when i zoom the
window, the color change can be seen. I am getting this problem after
switching from JRE 1.2.2 / J3D 1.1.3 to JRE 1.4.1 / J3D 1.3.

Has this anything to do with the Back / Front buffers / Clipping?

Thanks,
Raghav
