Hello, I have tried to use getCoordRef instead of getCoordinate, but still
the same error happens.
I have also tried to checked the capabilities but I don�t find anything
wrong. I post the code in which I set the capabilities:
//myScene is a Branchgroup
myScene = myLoadedScene.getSceneGroup();
myScene.setCapability(BranchGroup.ALLOW_CHILDREN_READ);
myScene.setCapability(BranchGroup.ALLOW_CHILDREN_WRITE);
myScene.setCapability(BranchGroup.ALLOW_CHILDREN_EXTEND);
//the scene loaded from the file is added to the total scene
//mySceneTG is a transformgroup
mySceneTG.addChild(myScene);
mySceneTG.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
mySceneTG.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
mySceneTG.setCapability(TransformGroup.ALLOW_CHILDREN_WRITE);
I post again the code where the error happens.
Please any help will do. Thank you very much in advance.
The error is:
GeometryArray: cannot directly access data in BY_REFERENCE mode
This is the code where it fails:
