# Spline

A spline is a mathematical curve that is used to interpolate or approximate a set of data points. Splines are commonly used in computer graphics and CAD applications to create smooth curves. There are several different types of splines, including cubic splines, Bezier splines, and B-splines. What does the spline function do? The spline function is a mathematical function that is used to interpolate or approximate data points that are spaced relatively far apart. Spline functions are smooth and continuous, and they can be used to create smooth curves that connect data points. What is spline tool? A spline is a mathematical curve that is used to interpolate or approximate data points. Spline tools are used to create smooth curves that pass through or approximate data points in a graphic. What is a spline shape? A spline shape is a type of shape that is created by connecting a series of points together with straight lines or curves. Spline shapes are often used in computer graphics and animation to create smooth, flowing shapes. Where did the word spline come from? The word 'spline' comes from the Latin word 'splineus', meaning 'string, cord, or thong'. It was first used in the 17th century to refer to a long, thin strip of wood or metal used to join two pieces of wood or metal together. In the 19th century, the word 'spline' began to be used in the field of mathematics, specifically in the study of curves and surfaces. In mathematics, a 'spline' is a curve that is piecewise-smooth, meaning that it is smooth in some parts and discontinuous in others. The word 'spline' is also used in the field of computer graphics, where it refers to a line or curve that is used to interpolate between points in a digital image.

##### What is a wood spline?

A wood spline is a thin, narrow piece of wood that is used to join two larger pieces of wood together. Splines are typically used in woodworking and carpentry, and are inserted into slots or grooves that have been cut into the two pieces of wood. The spline helps to strengthen the joint and can also be used to decorative effect.
