You can't use picktool on live or compiled object. 2 solutions :
1 - Do PickTool.setCapabilities(xxx) after object creation but before adding it to your scene (and use setPickable() method to change pickability at runtime) 2 - Or Detach the BranchGroup of your object, do the PickTool.setCapabilities(xxx) on your object, and re-attach the branchgroup (but this branch musn't be compiled) -----Message d'origine----- De : Brobbey,Isaac (neuron) [mailto:[EMAIL PROTECTED]] Envoy� : mardi 7 janvier 2003 15:05 � : [EMAIL PROTECTED] Objet : [JAVA3D] need help java3d code i am getting an error when i try to make two or more displays by repeatedly calling this method below: void enumKids(Group tg) { java.util.Enumeration enumKids = tg.getAllChildren(); while (enumKids.hasMoreElements()) { System.out.println("More elements to check"); SceneGraphObject sg = (SceneGraphObject) enumKids.nextElement(); if (sg instanceof Shape3D || sg instanceof Morph) { PickTool.setCapabilities((Node) sg, PickTool.INTERSECT_FULL); sg.setCapability(PickTool.INTERSECT_FULL); System.out.println("Capability = " + sg.getCapability(PickTool.INTERSECT_FULL)); } } } i am getting the following error Size of vector is 312 Exception in thread "main" javax.media.j3d.RestrictedAccessException: Cannot modify capability bits on a live or compiled object at javax.media.j3d.SceneGraphObject.setCapability(SceneGraphObject.java: 101) at com.sun.j3d.utils.picking.PickTool.setCapabilities(PickTool.java:283) at com.sun.j3d.utils.picking.PickTool.setCapabilities(PickTool.java:270) at Graphic.enumKids(Graphic.java:301) at Graphic.createConeTransformGroup(Graphic.java:277) at Graphic.createSceneGraph(Graphic.java:532) at Graphic.<init>(Graphic.java:684) at Tabed.<init>(Graphic.java:1393) at Graphic.main(Graphic.java:85) Is there any work around on the PickTool ? how can I modify the PickTool to make it work for two or more displays ? i am running out of Ideas , i will appreciate any help. thanks, isaac =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
