[JAVA3D] Behavior stops when minimized

Hi All, I am facing a peculiar problem with a J3D applet that implements a behavior. I have implemented a custom behavior for my DigitalClock class that wakes up every second by using WakeupOnElapsedTime(1000) as trigger. (It doesnt use any Alpha, yet). The clock runs smoothly updating display

Hi Saurabh > Is it possible to draw oval/ circle, using graphicsContext3D, on canvas3D > will highly appreciate any help or pointers Yes by using a Raster object and using it's imageComponent and it's bufferedImage you can draw 2d primitives (as usual) in the bufferedImage which will be displayed

Hi All! I got a simple question, and tell me if i'm stupid, but i can't find a solution right now... So, I'm using a 3ds-loader, that returns a Scene, that i converted to a BranchGroup an added to my SceneGraph. So long, so good. Now I want to set the Appearance of the loaded Objects but I've no

Thanks J.D. I now did it with a type of recursion. The Source is shown as followed. My last Question: Did this really find all Shape3D's? It takes the root - BranchGroup and follows the tree down if it found another BranchGroup or a TransformGroup. Or is there a better solution? Thanks in advanc

Re: [JAVA3D] Zooming

Hi, I think what you need is a MouseZoom object. Set the TransformGroup object as the argument to the MouseZoom object. MouseZoom zoomObj = new MouseZoom(); zoomObj.setTransformGroup(t3d); zoomObj.setSchedulingBounds(new BoundingSphere()); After this, adding your Shape3D objects to t3d

Re: [JAVA3D] Plz help!

If you are using primatives then perhaps the easiest thing is instead of using center of mass (which is not easy to calculate) is to get the bounds of the shape and then get the center. Bounds b = shape.getBounds(); if (b instance of BoundingSphere) { Point3d center = new Point3d(); ((Bou

Re: [JAVA3D] Plz, help!

Hi Ashish, a fast (but dirty) way to do this would be the following. Save the center of the object with the shape. This can be done by setting the user data field of a Shape3D using setUserData(); At creation time of the shapes you (hopefully) know the coordinates centers of the objects!!) P

hmmm, I guess I have to rephrase the question. I'm familiar to the fact that if we want to add/change a live object, exception handlers first check whether the neccessary capabilities were first set before the object could be changed. These handlers could then be considered as "listeners". I'm cu
