Principal Curvature is two numbers at each point, indicating the curvature of a surface in space. Calculate Principal Curvature Supposing S is a surface in \mathcal{R}^{3}, p is a point in S, N is a unit normal vector to S at p. Choose a plane \Pi passing through p and parallel ...
Finding the normal n to a smooth surface and calculating the directional derivative of a given function of three independent variables, forms a useful exercise in the application of the gradient operator in vector calculus. This exercise can be helpfully extended by taking the divergence ▽·[n...

Bounding surface positions using the control mesh, and bounding surface normals using normal cones, are both well known procedures. In this paper, we add to these, a procedure to bound the normal curvature values of a surface. We then show how collision free 5-axis tool-paths for CNC ...
Therefore, image analysis software was developed to determine whether the facial bone surface achieves a smooth curve after corrective surgery. The discrete curvature of a triangular mesh model was utilized in the assessment process8,9,10. Various polyhedral mesh models have been introduced to evaluate...
