Encapsulates 2D parameterization for pattern generators. Allows transformations and selection of arbitrary variables bound to primitives as well as handling of derivatives. Uses a simple struct to represent bundled dataflow of outputs.

Input Parameters

Angle

Rotation angle around origin.

Scale S

Frequency of a feature in the S direction.

Scale T

Frequency of a feature in the T direction.

Offset S

Offset from the origin in the S direction.

Offset T

Offset from the origin in the T direction.

Invert T

Flip the manifold in the T direction.

PrimVar S/ST

Name of custom 1D S or 2D ST primvar.

PrimVar T

Name of custom 1D T primvar.

Output Parameters

result

The 2D manifold.

resultS

A float representation of the S component of the manifold.

resultT

A float representation of the T component of the manifold.
