WebOct 6, 2024 · Using GHT-Bézier curves, they constructed some free-form complex curves with restriction of parametric continuity. To show the efficiency of modeling, the authors also constructed different types of symmetric curves and surfaces with their continuity conditions and symmetric formulas. WebParametric spline curves and surfaces are typically constructed so that some number of derivatives match where the curve segments or surface patches abut. If derivatives up to order n are continuous, the segments or patches are said to meet with Cn, or nth order parametric continuity. It has been shown previously that parametric continuity is … The terms parametric continuity (C ) and geometric continuity (G ) were introduced by Brian Barsky, to show that the smoothness of a curve could be measured by removing restrictions on the speed, with which the parameter traces out the curve.
