Hi, everybody.
recently, I get trouble about converting .dgn files( MicroStation'format) to
.osg ; I found dgn2osg plugin in osg'web sites, but it seems not to download
availably now.
I also can't find opendgn'sdk download from Google which support read/write dgn
files.
any advices,
Hi Sam,
You can't remove an object from it's a parent in a apply() method as
this would invalidate the iterators of the calling code (the
traverse() method that calls the node-accept() which in turn calls
the apply()).
It's safe to remove the children of a node you are passed in a the
apply
Hi Robert,
the second half of my post is about the second option you was talking about.
The apply only gathers the nodes in question and does nothing else then there
is another method that performs the removal from parent.
But the issue with that is, that if I do not call this method, no removal
Hi Sam,
You have complete control over what you do before and after traversal,
there really isn't any need to have a finalize method as it would only
restrict what users can do over what they can already do.
If you wanted an finialize method in your visitor then just write a
method like:

Hi Sam,
I simply don't get why your are expecting things from the NodeVisitor
that it isn't intended to provide, and what you can very simply
provide yourself.
There are many examples of NodeVisitor's in action in the OSG please
do a search through the code base.
Robert.

Hi Robert,
I suppose I expect that because let's say a RemoveGroupsVisitor should remove
Groups from a given graph, when I apply this visitor to a scene by
Code:
RemoveGroupsVisitor r;
scene-accept(r);
I personally would expect that now the groups are removed, which they are not
by the
Hi,
very good question, i am having the same problem i will keep u informed ;)
Thank you!

I would have a look at something like 'Deep Explorer' from right hemisphere, it
can convert a lot of formats to formats supported by OSG such as Multigen
OpenFlight(tm) of the top of my head I believe it supports dng format, once
converted to say OpenFlight you can use OSG to create your

Hi Sam,
Your expectations are unreasonable, please them recalibrate otherwise
you are going to constantly disappointed that everything in the world
doesn't conform to you prior conceptions. In the case of the
NodeVisitor where you are seeing a limitation, it's actually a

Hi Robert,
As I built the 3rdParty Package for VS2008 last year, I did a mistake and
removed the debug databases from the compile output, so in debug mode there are
lots of warnings due to missed .pdb files.
Should I rebuild the package content (would consume a lot of time I think), Or

Hi Robert,
im really sorry, i somehow missed out on your post on my first read. Thanks for
the detailed explanation. Well im a student and looking at the vastness of OSG,
i felt it would require quite a lot of time. So, i was looking for support from
the lower level APIs.
Thanks

My application is going to be run on different displays, some of which might be

does what it needs to do to make sure that
Hi,
that is exactly the point. My RemoveXVisitor SHOULD remove nodes but since it
is not possible to do that in apply and there is no finalize method that gets
automatically called after accept has finished, it is only possible to remove
nodes by providing a custom member which the user must
Can anyone help me with usage of Delaunay Triangulator in following case?

You haven't really said _what_ was jittering - is it your scene entities, or
your camera? If it is your entities, then what I am about to say won't really
apply to you. If it is your camera, then maybe it will give at least help to

You can declare and register a PostDrawCallback with the camera class to do

Hi,
I need to read all the vertex position and normal of a loaded flt model. I
tried using InfoVisitor to get all Geode nodes and get information on the
vertices but not sure how to do it.
Could someone advise how I should go about getting information on the vertex
position and normal?
Thanks a lot Shayne!
That really helped.
