Hi Simon,
I was similar problems with DirectDraw, i recommend you to download the J3D
version to OpenGL, it is more stable. I think there is a new version to
DirectDraw but I didn�t proved.
- to add children at runtime two things to consider:
1. Add the capabilities to the parent (no necessary a BranchGroup):
BranchGroup parent = new BranchGroup();
parent.setCapability(BranchGroup.ALLOW_CHILDREN_EXTEND);
parent.setCapability(BranchGroup.ALLOW_CHILDREN_READ);
parent.setCapability(BranchGroup.ALLOW_CHILDREN_WRITE);
// if you want to detach the branchgroup at runtime
parent.setCapability(BranchGroup.ALLOW_DETACH);
:
2.Only BranchGroups can be added at runtime(as you know):
BranchGroup child = new BranchGroup();
: // add any objects to child
:
parent.addChild(child); // add
