示例1:
SdfPath
UsdImagingMaterialAdapter::Populate(UsdPrim const& prim,
UsdImagingIndexProxy* index,
UsdImagingInstancerContext const* instancerContext)
{
// Since material are populated by reference, they need to take care not to
// be populated multiple times.
SdfPath cachePath = prim.GetPath();
if (index->IsPopulated(cachePath)) {
return cachePath;
}
index->InsertSprim(HdPrimTypeTokens->material,
cachePath,
prim, shared_from_this());
HD_PERF_COUNTER_INCR(UsdImagingTokens->usdPopulatedPrimCount);
// Also register this adapter on behalf of any descendent
// UsdShadeShader prims, since they are consumed to
// create the material network.
for (UsdPrim const& child: prim.GetDescendants()) {
if (child.IsA<UsdShadeShader>()) {
index->AddPrimInfo(child.GetPath(), child, shared_from_this());
}
}
return prim.GetPath();
}示例2: _VisitSubtree

_VisitPrim(prim);
auto range = prim.GetDescendants();
