In general, a curved line, made up of segments and defined by control points (for example, CVs). Types of splines include polylines, cardinal splines, B-splines, and non-uniform rational B-splines (NURBS). Splines were originally developed for shipbuilding. A way to draw a smooth curve through a set of points was needed. The solution was to place metal weights at points and pass a thin wooden beam between the weights. The beam, called a spline, adopts a minimum energy position with respect to the weights, producing a smooth curve. The influence of each weight is maximum at the point of contact, and decreases smoothly away from that point.
(n or v) A free-form curve that connects a series of control points with a smooth curve. Changing a control point results in a change in the curve. The term also describes the process of connecting points to create a curve. B-spline and Bezier curves are examples of spline curves.
In the mathematical subfield of numerical analysis, a spline is a special function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using low degree polynomials, while avoiding Runge's phenomenon for higher degrees.
A rectangular piece fitting grooves like key seats in a hub and a shaft, so that while the one may slide endwise on the other, both must revolve together; a feather; also, sometimes, a groove to receive such a rectangular piece.
A thin wood strip that is set into mating grooves in two joined pieces of stock. The grain direction of the spline is perpendicular to the joint to strengthen the joint. Splines are most commonly used in mitered corners of picture frames and for joining stock together edge-to-edge for tabletops and similar projects.
Machined longitudinal grooves in a shaft or spindle that act as a key/drive, ensuring the component being driven by the shaft or spindle does not slip during operation , example is the tapered windscreen blade drive spindles which are machined with splines on which the blade housings locate.
A piece of wood used in the production of fine furniture. A spline is used to hold two other pieces of wood together by intersecting the connection of those pieces of wood, thereby locking that intersection and making it impossible for them to separate.
1. A flat key or strip that its into a groove or slot between two parts. Alternately, the groove or slot into which it fits. 2. A long, flat, pliable strip of wood, used to strength two pieces of wood by joining. The strip (spline) fits into a groove cut into the two joined pieces. 3. The raised ridges evenly spaced around the circumference of a drive shaft or axle.
