Re: [JAVA3D] Origin of the 3dVector

[Saeed Ansari]

I have used the below code for angle of the view:

 

   ViewingPlatform vp = simpleU.getViewingPlatform();
   TransformGroup View_TransformGroup = vp.getMultiTransformGroup().getTransformGroup(0);
   Transform3D View_Transform3D = new Transform3D();
   View_TransformGroup.getTransform(View_Transform3D);
   View_Transform3D.setTranslation(new Vector3f(0.0f,0.0f,0.5f));
   View_TransformGroup.setTransform(View_Transform3D);

Is it correct or not ?

 

Regards,

is pretty much the same as

 

    Transform3D trans3D = new Transform3D();

The origin of course IS Vector3f(0.0f,0.0f,0.0f). If you cannot see anything ... where is your camera looking to?

 

(IIRC, ColorCube is visible w/o light, right? Otherwise, some ambient light in the scene would be helpful....)

Subject: [JAVA3D] Origin of the 3dVector

Hello,

I want to transfer a ColorCube.I am using Transform3D Class to locate the Color cube.

But when I set Location :

    Transform3D trans3D = new Transform3D();
    trans3D.setTranslation(new Vector3f(0.0f,0.0f,0.0f));

nothing appears, just a black screen.

I tested with another locations, and now I can't find where id the origin of the 3d Vector on

the screen.

Can you help me?
