hello
I do the following :
- i add a boundingleaf to the platformgeom and set a orbitbehavior:
iVpBoundingLeaf = new BoundingLeaf(new BoundingSphere(new
Point3d(0.0,0.0,0.0),100.0));
PlatformGeometry pg = new PlatformGeometry();
pg.addChild(iVpBoundingLeaf);
viewingPlatform.setPlatformGeometry(pg);
OrbitBehavior orbitBehavior = new
OrbitBehavior(canvas,OrbitBehavior.REVERSE_ALL);
orbitBehavior.setSchedulingBoundingLeaf(iVpBoundingLeaf);
orbitBehavior.setZoomFactor(50.0);
viewingPlatform.setViewPlatformBehavior(orbitBehavior);
- i construct a simpleuniverse with this viewplatform :
Viewer viewer = new Viewer(canvas);
viewer.getView().setBackClipDistance(10000.0);
iSimpleUniverse = new SimpleUniverse(viewingPlatform,viewer);
BranchGroup scene = createSceneGraph();
iSimpleUniverse.addBranchGraph(scene);
- i construct a directional light that has the boundingleaf as influencebounds
and add it to the graph :
DirectionalLight dirLight = new DirectionalLight(new
Color3f(1.0f,1.0f,1.0f),new Vector3f(0.0f,-1.0f,0.0f));
dirLight.setInfluencingBoundingLeaf(iVpBoundingLeaf);
objRoot.addChild(dirLight);
now the problem is :
When i zoom to far out the light suddenly is deactivated (so no intersection with
bounds).
When i give the boundingleaf a greater radius i can zoom out more.
This shouldn't be so , since the boundingleaf is attached to the platfgeom, isn't it?
It also doesn't make sense since i can still zoom out and in when the lights are off
but
the lights and the orbitbehavior use the same boundingleaf! so when the lights
deactivate,
I shouldn't be able anymore to zoom back so that they activate.
does someone know what I am doing wrong?
greetings,
mattie
