Well, I am using a behavior subclass to modify the view using lookAt()...and the keyboard....this works fine with projection...but when i do parallel and use ortho(), it is like everything is squeezed ... all I see is a line...(instead of all the objects in my universe)....i have messed with the ortho params to no end....and i still cannot see anything.....when i change the direction of view via the lookAt() method....the "line" seems to somehow change...it kind of blinks as i move...but i can't see anything....
I am wondering specifically....has anyone used the ortho() method....iand do you have to do:
view.setLeftProjection(t);
view.setRightProjection(t);
?
or do you have to do:
view.setVpcToEc(t);
?

There's nothing special I'm doing except for the fact that I'm using SimpleUniverse utility to create the view branch. In one of the method I use the following piece of code to set the parallel projection.m_universe.getViewer().getView().setProjectionPolicy(View.PARALLEL_PROJECTION);can you specify what happens when you set this policy?nitin-----Original Message-----

Did you try view.setProjectionPolicy(View.PARALLEL_PROJECTION)...that works just fine for me.cheers,nitin-----Original Message-----

Subject: [JAVA3D] Java3D - Orthographic viewsdoes anyone know how to set up an orthographic view?
I can do a perspective easy like shown below but orthographic doesn't work!!!!!!!
please help??????????
--------------------------------------------------
// perspective vars
double fovx = (double)(Math.PI*((double)1/2));
double aspect = (double)800.0/600.0;
double zNear = (double)3*100;
double zFar = (double)100000.0*100;
t.perspective(fovx, aspect, zNear, zFar);// ortho vars
double left = (double) 1000;
double right = (double) 1000;
double bottom = (double) 1000;
double top = (double) 1000;
double near = (double) 1;
double far = (double) 10000;
//t.frustum(left, right, bottom, top, near, far);
//t.ortho(left, right, bottom, top, near, far);view.setLeftProjection(t);
view.setRightProjection(t);
t.lookAt(new Point3d(1.0, 0.2, 0.0), // eye
new Point3d(0.0, 0.2 , 0.0), // center
new Vector3d(0.0, 1.0, 0.0)); // upview.setVpcToEc(t);
bounds =
new BoundingSphere(
new Point3d(0.0,0.0,0.0), 100*100000.0);
Transform3D t2 = new Transform3D();
ViewPlatform vp = new ViewPlatform();
vpTrans = new TransformGroup(t2);
vpTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE|
TransformGroup.ALLOW_TRANSFORM_READ);
vpTrans.addChild(vp);
vpRoot.addChild(vpTrans);DS = new doStuff(t, view);
DS.setSchedulingBounds(bounds);
vpTrans.addChild(DS);-------------------------------------------------
