Abstract
In this work, we use a kind of \(C^1\) rational interpolation splines in one and two dimensions to generate curves and surfaces with region control. Simple data-dependent sufficient constraints are derived on the local control parameters to generate \(C^1\) interpolation curves lying strictly between two given piecewise linear curves and \(C^1\) interpolation surfaces lying strictly between two given piecewise bi-cubic blending linear interpolation surfaces.
