示例1: createMaterialForPath
void
IfReplacer::replaceMaterials(SoNode *sceneRoot, const SoType &typeToReplace)
{
// Find all nodes of the given type
SoSearchAction sa;
sa.setType(typeToReplace);
sa.setInterest(SoSearchAction::ALL);
sa.apply(sceneRoot);
// Replace the tail of each path with a material. To do this, we
// need to apply an SoCallbackAction to the path to gather the
// material components.
for (int i = 0; i < sa.getPaths().getLength(); i++) {
// Cast the path to a full path, just in case
SoFullPath *path = (SoFullPath *) sa.getPaths()[i];
ASSERT(path->getTail()->isOfType(typeToReplace));
// The path better have at least one group above the material
if (path->getLength() < 2 ||
! path->getNodeFromTail(1)->isOfType(SoGroup::getClassTypeId()))
continue;
// Create a material node that represents the material in
// effect at the tail of the path
SoMaterial *newMaterial = createMaterialForPath(path);
newMaterial->ref();
// Replace the tail node with that material
SoGroup *parent = (SoGroup *) path->getNodeFromTail(1);
parent->replaceChild(path->getTail(), newMaterial);
newMaterial->unref();
