Curvature of Surfaces - Maths

WebOne method used to measure the Gaussian curvature of a surface at a point is to take a small circle of radius on the surface with centre at that point and to calculate the circumference or area of the circle. If the circumference is and the area is the surface is flat and is said to have zero curvature. WebTo check for curvature. Centerpoint runs are not randomized ... Rough rule of thumb is to add 3 to 5 center point runs to your design: With this in mind, we have to decide on how many centerpoint runs to do.
