Detailed Description

Callback for collecting axis points and then calculating the current transform from those axis points.

Sanity checking of the axis points was applied earlier when the axis points were added/edited.

Member Function Documentation

◆ transformIsDefined()

bool CallbackUpdateTransform::transformIsDefined ( ) const

True if enough Points were available to create a Transformation.

Except for the node count, all other failure modes are caught externally so user gets immediate feedback as soon as bad axis point data appears
