Hi Morten:
Yesterday I changed my code, and now the count reference (I see it with the get Count reference Method) goes to zero when I  "unref()" the node, but the element (for example an sphere) stills remains there, as I read in the inventor Mentor, if you unref() and the count reference goes to zero the node is deleted from the scene.
Thanks Morten!.

Are you just calling unref() on a node that is the child of a group, or do you also use SoGroup::removeChild()? You shouldn't just unref() a node you haven't decided to manage yourself by ref()ing it earlier. The refs for child nodes of groups are handled by their parent group node, so only if you have called an additional ref() on it should you ever unref() it. You should just use removeChild() to remove a node from a group.

Otherwise, what I suspect is going on, is that the parent node is still using the memory area of the (now deleted) child node. (Normally, that would cause a crash, but due to the peculiarities of C/C++, by freak accident it could "work".) Either that, or there is something else weird going on, like e.g. perhaps you have several spheres at the same spatial location, or some such.

I get the parent and child from my map, and delete it with that function, I was wishing that function exists,but as I didn't read about it in the Inventor Mentor I was fearing it didn't!! Now I am searching for the function I saw to interchange the position of two nodes within a tree, to implementate to push buttons for the user to move down and up nodes within a branch of the tree.

It would go something like this: childA->ref(); // make sure ref-count don't go to zero parentX->replaceChild(childA, childB); parentY->replaceChild(childB, childA); childA->unref(); // set back ref-count ..where parentX is the original parent of A, and parentY for B.

I could give a small paypal gift to the person solving the “equation”. What I'm trying to do is to use OpenGL and OpenInventor in the same GL context and using the same camera for OpenGL and OpenInventor. This camera is the SoCamera from the OpenInventor package. This mean something like this: void draw(){ drawTheInventorStuff(); drawTheOpenGLStuff(); } The problem is that I cant get the same exact visualization coordinates for OpenGL and OpenInventor with the SoCamera and I dont know why. I have been reading a lot on the SoCamera and looking at the source code to finally isolate what I think are the two functions needed for my task : SbViewVolume::getMatrix() and SbViewVolume::getMatrices( sbMatrixAffine , sbMatrixProjection) . Basically, at the moment, what I do is to take the SbViewVolume from the camera and getMatrix: SbViewVolume cameraSbViewVolume; cameraSbViewVolume = camera->getViewVolume(); sbMatrixCamera= cameraSbViewVolume.getMatrix();//working then I use glMatrixMode(GL_PROJECTION); glLoadIdentity (); glMultMatrixf(sbMatrixCamera[0]); before drawing my GL stuff to get the same camera view than in my OpenInventor rendering pipeline. Its working for the exception of an annoying perspective problem or Viewport Ratio problem and I dont know how to solve it. I invite you to take a look at the problem by looking at a small video you can find at: http://www.netchilds.com/Louis/test.mpeg (If everything worked correctly, you could see only one plane and one 6 DOF mechanism but its not the case. You will notice I have the same problem with perpective and ortho camera.) If you know how to solve the problem, what matrix or GL call I should be using please message me todumais01@gmc.ulaval.ca . I'm including the code below I'm using in the video to give you a better idea of my problem.

Specifically, in SoTransform::doAction there are the following lines: if (! rotation.isIgnored() && ! rotation.isDefault()) SoModelMatrixElement::rotateBy(state, this, rotation.getValue()); If the rotation is very small (a couple of degrees or less), small changes to the rotation will not change what is drawn on the screen after the SoTransform in the Inventor tree. What's happening is that the quaternion representation of the rotation is converted to an axis/angle representation in SoGLModelMatrixElement.c++ in the method SoGLModelMatrixElement::rotateEltBy. This is immediately handed to the OpenGL command glRotatef ( angle, x, y, z ) which then converts it to a matrix and multiplies it by the current Model Matrix. The conversion from quaternion to axis/angle uses an "acosf" function and the conversion from axis/angle to matrix uses sin and cos. (And glRotatef is one of those "not to be trusted" functions in OpenGL.) Precision is lost with these trig functions near zero. The result is that a rotation angle change from 0.020 to 0.023 doesn't change what's drawn on the screen at all. It should. Certainly, not that big of a deal, really, but it doesn't have to be that way. Here's the fix. Go to SoTransform.c++ and change the above lines to: if (! rotation.isIgnored() && ! rotation.isDefault()) { SbMatrix rot_mat; rotation.getValue ( rot_mat ); SoModelMatrixElement::mult ( state, this, rot_mat ); } Converting a quaternion directly into a matrix is much more accurate (no trig functions!) and probably just as fast. Alternately, and probably more general of a solution, is to change in SoGLModelMatrixElement.c++ void SoGLModelMatrixElement::rotateEltBy(const SbRotation &rotation) // //////////////////////////////////////////////////////////////////////// { SbVec3f axis; float angle; SoModelMatrixElement::rotateEltBy(rotation); rotation.getValue(axis, angle); glRotatef(angle * (180.0 / M_PI), axis[0], axis[1], axis[2]); } to void SoGLModelMatrixElement::rotateEltBy(const SbRotation &rotation) // //////////////////////////////////////////////////////////////////////// { SbMatrix rot_mat; SoModelMatrixElement::rotateEltBy(rotation); rotation.getValue( rot_mat ); glMultMatrixf((float *) rot_mat.getValue()); } Respectfully submitted, Doug P.S.
