Polyline, английский
- A bezier path made of segments that are either straight lines or circular arcs.
- A tool to create a bezier path made of segments that are either straight lines or circular arcs.
- Линия специального типа, обладающая следующими свойствами: набор ее сегментов считается одним объектом; она может включать дуги других кривых линий; она может быть сглажена в кривую; она имеет толщину в двух измерениях.
Polyline arc, английский
Дуга, ограниченная ломаной линией
Polyline area, английский
Polyline outline, английский
Полилинейный контур; контур, образуемой ломаной линией

Spline, английский
- A spline is a mathematical function defined over a compact region of a (continuous) variables range. it is generally continuous and is often represented by a low order polynomial function (or its integral). the knots of a spline are its points of inflection. its degree is a measure of the number of continuous derivatives. these functions underlie many data mining and nonparametric or semi-parametric regression functions. since they are only defined over a region of the full attribute range, they allow the function to adapt well to data in their region of support without strongly influencing the results in regions outside that region. techniques such as classification and regression trees (cart) and c4.5 that recursively partition the attribute space can be thought of as recursive spline functions with zero-order splines (constant values) fit in each region. the attributes in each sub-region so defined can then be searched for further places to partition that region adaptively for improved prediction. see also: c4.5, classification and regression trees, multivariate adaptive regression spline, nonparametric. split-sample validation a method for estimating the error in automated modeling techniques such as neural networks, recursive partitioning, and data mining. the data are split into two parts, a larger part for estimation and a small hold out sample used to estimate the true error. the technique is best used when there is a very large amount of data available as it reduces the size of the training data.
- A curved line, made up of segments and defined by control points.
Spline insert, английский

Spline joint, английский
A joint formed by inserting a spline in a slot cut into the two butting members. split 1. a rupture in a built-up roof membrane, resulting from tensile stresses. 2. a crack that extends completely through a piece of wood or wood veneer. 3. a brick cut lengthwise, in two pieces, parallel to the wide face of the brick, so that it is half as thick; also called scone. spliced pile 922 spline, false tongue, feather, slip feather, slip tongue 1. a long thin strip of wood or spline, 1 splice plate spline, 2 split, 3
Spline rolling machine, английский
Spline shaft, английский
Spline shaft hobbing machine, английский
Spline. false window, blind window the representation of a window inserted to complete a series of windows or to give symmetry; a blank window., английский
Spline. slip form, sliding form in concrete construction, a form designed to move upward slowly (usually by means of hydraulic jacks or screw jacks), supported by the hardened concrete of the wall section which was poured previously., английский
Spline. slip-tongue joint a spline joint., английский
Splined, английский
Splined interpolation, английский
One of three methods used to describe how an animation transitions between values over its duration. this method uses a bezier curve to describe how the animation transitions between key frames. the bezier curve starts at zero, which corresponds to the current key frame value, and ends at one (the next key frame’s value). by altering the curve’s two control points, you alter the animation’s progress curve. split (v)
