Computes the world transform of a prim.

Calculates the complete world transform by:

1. Checking for world transform attributes (position, orientation, scale)

2. Falling back to local transform computation if world transform unavailable

3. Recursively computing parent transforms when needed

The function handles three cases:

• Prims with world transform attributes

• Prims with local transform only

• Regular USD prims without USDRT extensions

Warning

May be computationally expensive for deep hierarchies

Parameters:

• usdStage – [in] Reference to the USD stage

• usdrtStage – [in] Reference to the USDRT stage

• path – [in] Path to the prim whose transform to compute

• timecode – [in] Time code for the transform evaluation (default: Default())

• useFabricHierarchy – [in] Whether to use IFabricHierarchy (default: false). If enabled, but Fabric Scene Delegate (/app/useFabricSceneDelegate) is not enabled, the call will fall back to non-IFabricHierarchy implementation. Note: Using IFabricHierarchy is experimental and enabling it may result in undefined behavior.

Returns:

usdrt::GfMatrix4d The computed world transform matrix
