問題 #20
What geometric attribute should be kept in sync when updating point position values on an object?

答案：C

解題說明：
The geometric attribute that should be kept in sync is extent. In OpenUSD, point position values describe the authored point locations for point-based geometry, while extent represents the local-space geometric range or bounding box of a boundable primitive. The OpenUSD UsdGeomBoundable specification describes extent as a three-dimensional range measuring the authored gprim in its own local space, and states that if extent is authored, it should be authored at every time sample where geometry-affecting properties are authored to ensure correct evaluation.
Option C is correct because changing point positions can change the object's local bounds. If the authored extent is not updated, downstream systems may compute incorrect framing, culling, selection bounds, or bounding-box display. Option A is incorrect because purpose classifies geometry for render, proxy, guide, or default visibility categories. Option B is incorrect because xformOps describe transform operations on the prim, not the local geometric bounds derived from point positions. Option D is incorrect because faceVertexIndices describes mesh topology, not the bounding range. This aligns with Data Modeling # Geometry Attributes, Point-Based Geometry, Boundable Prims, Extent, and Time-Sampled Geometry .


問題 #21
Where should validation (usdchecker/Asset Validator) be run?

答案：D

解題說明：
Validating at each stage isolates issues and prevents regressions.


問題 #22
Consider the following prim hierarchies. Each prim hierarchy is represented by nested unordered lists and each list item represents a prim with the following format: PRIM_NAME (KIND). No text within the parentheses means that the kind is unset for that prim. Only evaluate model kind hierarchy correctness and the structural choices. Which prim hierarchies represent valid model kind hierarchies? Choose three.

答案：B,C,D

解題說明：
The valid model kind hierarchies are A, B, and E . NVIDIA's Learn OpenUSD material defines group, assembly, and component as model kinds, while subcomponent is explicitly outside the model hierarchy. The hierarchy rule is that all ancestors of a component must be group or a subkind of group, such as assembly, and a component acts as a leaf or pruning point in the model hierarchy; therefore, it cannot contain descendant model kinds such as another component, group, or assembly. ( NVIDIA Docs ) A is valid because CarA is a component and every descendant has unset kind, so no nested model violates the component boundary. B is valid because CarA is an assembly, organizational containers use group, and the leaf model assets are component prims. E is valid because CarA is a component, and internal important parts are marked as subcomponent, which is permitted inside a component and does not count as a model kind. C is invalid because a component contains descendant component prims. D is invalid because Wheels (group) appears under a component, placing a model kind below a component boundary. This aligns with Content Aggregation # Asset Structure # Model Hierarchy # Model Kinds .


問題 #23
What should be avoided when using computational workstreams?

答案：B

解題說明：
Dynamically growing stacks can lead to large overhead, so they should be avoided.


問題 #24
In OpenUSD, what is a common way to represent a modeling and shading workflow?

答案：B

解題說明：
Geometry and shading are authored in separate layers and composed into a unified asset with a layer stack.
