Hi Gareth,
Java 3D allows collision culling. The default is that everything is
collidable. The two relevant methods from the Node class are:
void setCollidable(boolean collidable)
Sets the collidable value; determines whether this
node and any of its children, if a group node, can
be considered for collision purposes.
boolean getCollidable()
Returns the collidable value; this value determines
whether this node and it's children, if a group
node, can be considered for collision purposes; if
it is set to false, then neither this node nor any
children nodes will be traversed for collision
purposes; the default value is true.
In addition to achieving what you want, collision culling can also
enable an application to be more efficient, since the culled parts of
the scene graph will be ignored by the Java 3D collision code.
