[osg-users] What's the difference between member of osgUtil::Intersector::CoordinateFrame?
Hello everyone, I'm making PickHandler inherit from osgGA::GUIEnentHandler. This class implememt Pick function. In this Pick func., there are PolytopeIntersector. And I use it as follows osgUtil::PolytopeIntersector* pPicker = new osgUtil::PolytopeIntersector( osgUtil::Intersector::WINDOW, dX - dW, dY - dH, dX + dW, dY + dH ); Here, I wonder what is the difference between osgUtil::Intersector::WINDOW, VIEW, and so on.

[osg-users] Plugins vrml compile error, and so on
1. 'Plugins vrml' compile error
I tried to compile 'Plugins vrml'
I follows that,
http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/Vi
sualStudio/VisualStudioPlugins
After all, I succeed compiling in 'Debug mode'. But in 'Release mode'
compiling, occur compile error.
[Error messege]
fatal error LNK1104: Can not open file 'LIBC.lib' Plugins vrml
What the problem?
2. Loading VRML file in program problem
osgDB::readNodeFiles("filename");
This code does not work.

Re: [osg-users] How to load VRML file in OSG?

If you want .wrl support then you need to compile either the vrml or iv plugins, for these you'll need OpenVRML or Coin respectively. This topic has been covered a number of times recently so please check through the archives.

Re: [osg-users] How to load VRML file in OSG?
Thanks for your answer. :-)
Then,
in OSG(2.4) what I have does not include vrml plugin, even other plugin is
included.
So, I can't complie vrml plugin or get complied vrml plugin.
Did I miss some file?

First, be sure that you compiled the vrml plugin, and that it resides in
you environmet path.
You don't say if you want to load your model from console or
programmatical.
From a console, type:
osgviewer.exe youfile.wrl
To see how this is achieved programmatical, have a look in the source code
to osgviewer (applications\osgviewer\osgviewer.cpp).
This line is relevant for you:
osg::ref_ptr loadedModel = osgDB::readNodeFile("youfile.wrl");

Re: [osg-users] How to change shape?
Hi Robert, I'm so surprised, because I received mail from you. :-) Thanks for your help. I solved the problem with your solution. Thanks! I think OSG is so cool graphic library! I am having developed some graphic library for 3d robot simulator, about for 1years. OSG is very good for this. ^^ I hope that I am good at using OSG, sooner or later.

Hi Jeongseok, By default the OSG uses display lists to speed up rendering, but the downside is that rendering once built into the display lists won't be updated automatically. To get ShapeDrawable to update the display list simple do drawable->dirtyDisplayList(false). Robert.

Re: [osg-users] Some 'osg::Geode' that can be transformed should be made as 'osg::MatrixTransform'?
Hi, Gordon and Vincent!
Thanks for answering my question.
I designed as following.
class XGLink : public osg::MatrixTransform
{ . }
After that, I wanna add some drawables into XGLink.
But XGLink is not a Geode. (osg::Drawable is can be add to only Geode)
So, I need to addChild (new Geode) into XGLink. And I addDrawable
osg::Drawable to the new Geode.
[ hierarchy ]
XGLink (osg::Group)
|
XGLinkGeode (osg::Geode)
|
XGDrawable (osg::Drawable)
Is this correct?
Ps. I cannot speak English so well. Please understand me J
Ps. How to reply again to reply? T-T

If you want to change the position / orientation of this node and its
children as in a shoulder of an arm then is really HAS to be a
transformation node and not a basic group or node
What's is the issue with using a transform node for what it is designed to
do ?

Hi,
osg::group inherit from osg::node, so a group is a node.
Is it your question ? or it is more complicated ?
2008/5/6 Jeongseok Lee <[EMAIL PROTECTED]>:
Hi all.
This is my first question to all of you.
So, it's very naive question. J
I'm developing 3D robot dynamics simulator.
There are links of robot in that simulator. And the links can move
(transform). So I used 'osg::MatrixTransform'. But this a kind of
osg::Group. I wanna make link as 'osg::Node'.
How am I suppose to do?
