a spatial transform defined by a callable and an optional inverse callable

Syntax

T = spatialTransformHandle(fun, funInv)
moved = T * pos

Description

The callable receives vector3d positions and must return their transformed positions, rather than their displacements. It is responsible for preserving the required shape, frame and z coordinates. Supply funInv to enable T.inv(); without it, requesting an inverse raises ValueError. The inverse callable receives positions in the output space.

Input

fun callable mapping input positions to output positions
funInv inverse callable, or None if no inverse is provided

Output

T spatialTransformHandle

See also

spatialTransform, spatialTransformInverse

Members

eval the positions the function returns
inv the transform of the inverse function, an error where none was given
paramChar the name of the function as a line of text
