Surface Analysis

• Curvature Evaluation

• Gaussian curvature of a surface.
• Mean curvature of a surface.
• Absolute curvature of a surface.
• Total curvature of a surface.
• Second order smoothness of a spline surface.
• Third order smoothness of a spline surface.
• Express the Gaussian curvature of a B-spline or NURBS surface as a NURBS surface.
• Express the second order curvature of a B-spline or NURBS surface as a NURBS surface.
• Curvature on a uniform grid of a spline surface.
• Principal curvatures of a surface.
• Normal curvature of a surface.
• Focal values on a uniform grid of a NURBS surface.
