Detailed Description

This schema specifies a cubic hermite interpolated curve batch as sometimes used for defining guides for animation. While hermite curves can be useful because they interpolate through their control points, they are not well supported by high-end renderers for imaging. Therefore, while we include this schema for interchange, we strongly recommend the use of UsdGeomBasisCurves as the representation of curves intended to be rendered (ie. hair or grass). Hermite curves can be converted to a Bezier representation (though not from Bezier back to Hermite in general).

Point Interpolation

The initial cubic curve segment is defined by the first two points and first two tangents. Additional segments are defined by additional point / tangent pairs. The number of segments for each non-batched hermite curve would be len(curve.points) - 1. The total number of segments for the batched UsdGeomHermiteCurves representation is len(points) - len(curveVertexCounts).

Primvar, Width, and Normal Interpolation

Primvar interpolation is not well specified for this type as it is not intended as a rendering representation. We suggest that per point primvars would be linearly interpolated across each segment and should be tagged as 'varying'.

It is not immediately clear how to specify cubic or 'vertex' interpolation for this type, as we lack a specification for primvar tangents. This also means that width and normal interpolation should be restricted to varying (linear), uniform (per curve element), or constant (per prim).

Constructor & Destructor Documentation

UsdGeomHermiteCurves::UsdGeomHermiteCurves ( const UsdPrim & prim = UsdPrim() )

inlineexplicit

Construct a UsdGeomHermiteCurves on UsdPrim prim . Equivalent to UsdGeomHermiteCurves::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 81 of file hermiteCurves.h.

UsdGeomHermiteCurves::UsdGeomHermiteCurves ( const UsdSchemaBase & schemaObj )

inlineexplicit

Construct a UsdGeomHermiteCurves on the prim held by schemaObj . Should be preferred over UsdGeomHermiteCurves(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 89 of file hermiteCurves.h.

Member Function Documentation

USDGEOM_API UsdSchemaKind UsdGeomHermiteCurves::_GetSchemaKind ( ) const

overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also: UsdSchemaKind

Reimplemented from UsdGeomCurves.

USDGEOM_API UsdAttribute UsdGeomHermiteCurves::CreateTangentsAttr	(	VtValue const &	defaultValue = `VtValue()`,
		bool	writeSparsely = `false`
	)		const

See GetTangentsAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create. If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

static USDGEOM_API UsdGeomHermiteCurves UsdGeomHermiteCurves::Define	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Attempt to ensure a UsdPrim adhering to this schema at path is defined (according to UsdPrim::IsDefined()) on this stage.

If a prim adhering to this schema at path is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path at the current EditTarget. Author SdfPrimSpec s with specifier == SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.

The given path must be an absolute prim path that does not contain any variant selections.

If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.

Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

static USDGEOM_API UsdGeomHermiteCurves UsdGeomHermiteCurves::Get	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Return a UsdGeomHermiteCurves holding the prim adhering to this schema at path on stage. If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

UsdGeomHermiteCurves(stage->GetPrimAtPath(path));

static USDGEOM_API const TfTokenVector& UsdGeomHermiteCurves::GetSchemaAttributeNames ( bool includeInherited = true )

static

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.

USDGEOM_API UsdAttribute UsdGeomHermiteCurves::GetTangentsAttr ( ) const

Defines the outgoing trajectory tangent for each point. Tangents should be the same size as the points attribute.


Declaration	`vector3f[] tangents = []`
C++ Type	VtArray<GfVec3f>
Usd Type	SdfValueTypeNames->Vector3fArray
