HUD visible to all Viewers

[saloisio]

I'm currently using the HUD package from http://www.newdawnsoftware.com/resources/newdawnhud.zip . It works really great, except for one thing: viewers in the same scene can see each other's HUDs! They look like 2D graphics that follow the ViewPlatform transform of each Viewer. Is there a way to hide the HUD from the sight of other Viewers in the same scene?

Hi
 When you say other players, how do multiple people play, do you do a split screen thing, or are they networked?.

Hi,

My application doesn't support multiple players, only one. That one player has both a first-person-view with a HUD, and a third-person-view (without a HUD). Both of these views (with their own Canvas3Ds) are visible at the same time. So I guess you'd say it's sort of a "split-screen" setup.

The problem is that from the third-person-view camera, the HUD that's attached to the first-person-view camera is visible. By "visible" I don't mean that it's showing in full screen as in the first-person-view, it sort of looks like a 2D projection attached to the first-person-view camera.

The first-person-view camera is attached to a 3D model. So when the model rotates this camera can see exactly what the model is facing. If the model is facing the third-person-view camera, the HUD isn't visible. But as soon as I start rotating the model past about 90 degrees the HUD becomes visible (on the third-person-camera).

Hi
 How do you go about creating your PhysicalHUD object?

This is the code I use to create the HUD:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26

// Creating PlatformGeometry PlatformGeometry hudPlatformGeometry = new PlatformGeometry(); hudPlatformGeometry.setCapability(PlatformGeometry.ALLOW_CHILDREN_WRITE); hudPlatformGeometry.setCapability(PlatformGeometry.ALLOW_CHILDREN_READ); hudPlatformGeometry.setCapability(PlatformGeometry.ALLOW_CHILDREN_EXTEND); // Creating GraphicsConfiguration GraphicsConfigTemplate3D gTempl3D = new GraphicsConfigTemplate3D(); gTempl3D.setDoubleBuffer(GraphicsConfigTemplate3D.PREFERRED); gTempl3D.setSceneAntialiasing(GraphicsConfigTemplate3D.PREFERRED); gTempl3D.setStereo(GraphicsConfigTemplate3D.PREFERRED); GraphicsConfiguration graphicsConfig = GraphicsEnvironment.getLocalGraphicsEnvironment().                       getDefaultScreenDevice().getBestConfiguration(gTempl3D); // Assign GraphicsConfiguration to the Canvas3D Canvas3D aCanvas = new Canvas3D(graphicsConfig); // Create the PhysicalHUD PhysicalHUD hud = new PhysicalHUD(MAX_NUM_OF_HUD_LAYERS, aCanvas3D, hudPlatformGeometry, 4f); // Create a Viewer using aCanvas and hudPlatformGeometry Viewer ptiViewer = new Viewer(aCanvas); ViewingPlatform ptiPlatform = new ViewingPlatform(); ptiViewer.setViewingPlatform(ptiPlatform); ptiPlatform.setPlatformGeometry(hudPlatformGeometry);

After this I just add the ViewingPlatform to my scene graph. Please let me know if you require further clarification. Thank-you.
