Defines a batched Linear UsdGeomBasisCurves prim on the stage.

This is an overloaded member function, provided for convenience. It differs from the above function only in what arguments it accepts.

Parameters:

• parent – Prim below which to define the curves.

• name – Name of the curves.

• curveVertexCounts – The number of vertices in each independent curve. The length of this array determines the number of curves.

• points – Vertex/CV positions for the curves described in local space.

• wrap – Determines how the start and end points of the curve behave. Accepted values for linear curves are UsdGeomTokens->nonperiodic and UsdGeomTokens->periodic.

• widths – Values for the width specification for the curves.

• normals – Values for the normals primvar for the curves. If authored, the curves are considered oriented ribbons rather than tubes.

• displayColor – Values to be authored for the display color primvar.

• displayOpacity – Values to be authored for the display opacity primvar.

Returns:
