Data Modeling: Quick Reference
This quick reference guide focuses on key aspects of Value Types, timeSamples, and Built-in Schemas relevant to the NVIDIA-Certified Professional: OpenUSD Development certification.
Value Types
Value types in OpenUSD define the kind of data that can be stored in properties. Here are the primary value types:
- Float: Represents decimal numbers.
- Int: Represents integer values.
- String: Represents text data.
- Bool: Represents boolean values (true/false).
- Token: Represents a symbolic string that is often used for identifiers.
- Asset: Represents references to external assets.
timeSamples
timeSamples allow for the representation of animated properties over time. Key points include:
- Each property can have multiple timeSamples associated with it.
- timeSamples are indexed by time, allowing for precise control over animation.
- They enable the storage of different values at different times, facilitating smooth transitions in animations.
Built-in Schemas
Built-in schemas provide predefined structures for common use cases. Important built-in schemas include:
- UsdGeom: For geometric shapes and transformations.
- UsdShade: For shading and material definitions.
- UsdRender: For rendering settings and configurations.
- UsdLux: For lighting definitions.
Understanding these components is crucial for effectively building and managing 3D content creation pipelines using OpenUSD.
