示例1: ASSERT
void
IfWeeder::weedMaterial(SoNode *root, IfWeederMaterialEntry *entry)
{
// If the material affects no shapes at all, get rid of it. This
// can happen when vertex property nodes are used.
if (entry->shapes.getLength() == 0) {
SoSearchAction sa;
sa.setNode(entry->material);
sa.setInterest(SoSearchAction::ALL);
sa.apply(root);
for (int i = 0; i < sa.getPaths().getLength(); i++) {
SoPath *path = sa.getPaths()[i];
SoSeparator *parent = (SoSeparator *) path->getNodeFromTail(1);
int index = path->getIndexFromTail(0);
ASSERT(parent->isOfType(SoSeparator::getClassTypeId()));
ASSERT(parent->getChild(index) == entry->material);
parent->removeChild(index);
}
}
// Remove all material values from the material node that are
// not used by any dependent shapes. Adjust the indices in the
// dependent shapes accordingly.
removeDuplicateMaterials(entry);
// Now remove all material values that are not used by any
// dependent shapes. Again, adjust the indices in the dependent
// shapes.
removeUnusedMaterials(entry);
