Visualize OCC shape in Open Inventor

Hi Patrik,

Thank you so much for your suggestion, One more thing i am working on this manipulators and draggers in coin3D, Actually i executed the example given in OpenInventor Manual, It is working properly, Now i am trying to attach the manipulator and dragger to the Iges file which i hav visualized using IndexedFacet, The Following function is called in the example which they have given, They are using callback function with SoSelection to select the nodes in the graph.

void selectionCallback(void *, SoPath *selectionPath)
{
// Attach the manipulator.
// Use the convenience routine to get a path to
// the transform that effects the selected object.
SoPath *xformPath = createTransformPath(selectionPath);
if (xformPath == NULL) return;
xformPath->ref();

// Attach the handle box to the sphere,
// the trackball to the cube
// or the transformBox to the wrapperKit
if (selectionPath->getTail()->isOfType(
SoSphere::getClassTypeId())) {
handleBoxPath = xformPath;
myHandleBox->replaceNode(xformPath);
}
else if (selectionPath->getTail()->
isOfType(SoCube::getClassTypeId())) {
trackballPath = xformPath;
myTrackball->replaceNode(xformPath);
}
}

And The Below function for creating TransformPath
SoPath *
createTransformPath(SoPath *inputPath)
{
int pathLength = inputPath->getLength();
if (pathLength < 2) // Won't be able to get parent of tail
return NULL;

SoNode *tail = inputPath->getTail();

// CASE 1: The tail is a node kit.
// Nodekits have built in policy for creating parts.
// The kit copies inputPath, then extends it past the
// kit all the way down to the transform. It creates the
// transform if necessary.
if (tail->isOfType(SoBaseKit::getClassTypeId())) {
SoBaseKit *kit = (SoBaseKit *) tail;
return kit->createPathToPart("transform",TRUE,inputPath);
}

SoTransform *editXf = NULL;
SoGroup *parent;
SbBool existedBefore = FALSE;

// CASE 2: The tail is not a group.
SbBool isTailGroup;
isTailGroup = tail->isOfType(SoGroup::getClassTypeId());
if (!isTailGroup) {
// 'parent' is node above tail. Search under parent right
// to left for a transform. If we find a 'movable' node
// insert a transform just left of tail.
parent = (SoGroup *) inputPath->getNode(pathLength - 2);
int tailIndx = parent->findChild(tail);

for (int i = tailIndx; (i >= 0) && (editXf == NULL);i--){
SoNode *myNode = parent->getChild(i);
if (myNode->isOfType(SoTransform::getClassTypeId()))
editXf = (SoTransform *) myNode;
else if (i != tailIndx && (isTransformable(myNode)))
break;
}
if (editXf == NULL) {
existedBefore = FALSE;
editXf = new SoTransform;
parent->insertChild(editXf, tailIndx);
}
else
existedBefore = TRUE;
}
// CASE 3: The tail is a group.
else {
// Search the children from left to right for transform
// nodes. Stop the search if we come to a movable node.
// and insert a transform before it.
parent = (SoGroup *) tail;
int i;
for (i = 0;
(i < parent->getNumChildren()) && (editXf == NULL);
i++) {
SoNode *myNode = parent->getChild(i);
if (myNode->isOfType(SoTransform::getClassTypeId()))
editXf = (SoTransform *) myNode;
else if (isTransformable(myNode))
break;
}
if (editXf == NULL) {
existedBefore = FALSE;
editXf = new SoTransform;
parent->insertChild(editXf, i);
}
else
existedBefore = TRUE;
}

// Create 'pathToXform.' Copy inputPath, then make last
// node be editXf.
SoPath *pathToXform = NULL;
pathToXform = inputPath->copy();
pathToXform->ref();
if (!isTailGroup) // pop off the last entry.
pathToXform->pop();
// add editXf to the end
int xfIndex = parent->findChild(editXf);
pathToXform->append(xfIndex);
pathToXform->unrefNoDelete();

return(pathToXform);
}

Now What i want is to select the Iges File which is in a IgesRoot(SoSeparator), In the Above function they have taken the ClassTypeID using SoCude->getClassTypeID() which will select the particular from the main ROOT, I used SoSeparator->getClassTypeID() but i am not able to slect my IGESRoot, Please help me...Looking Forward for your reply

Thanks & Regards
