(degree + 1), then the curve will split in disjoint parts and the control point will be unused. That u=1 at start and u=2 at end or u=10 at start and u=100 at end. Value to the parametric equation of line and calculate the coordinates at middle point.You can also assume Mathematical term you will say that what should be coordinates of point at u=0.5. If you are asked to find the coordinates of point, which lies at middle of the line, then in

Also assume that u=0 at start and u=1 atД®nd. Let'sДЄssume that there is a line starting at (1,1) and ending at (2,2). So at middle of the curve the value of u will be 0.5. Generally it is assumed that u is 0ДЄt the start of the curve and 1 at the end. The coordinates of a point, on the curve, from its parametric equation. In nurbs-calculator I call this parameter as u parameter. In mathematics, the equation of a curve can be expressed as a function of an independent variable, calledДЄs a parameter. So you need atleast 4 control points for degree Render a NURBS curve is the same as the order of the curve. The minimum number of control points required to Position, z position and weight of the control point. Each point is having 4 float values вЂ“ x position, y The control points determine the shape of the curve. The degree of the curve is integer and should be > 0. In most of NURBS applications you will find curves Is called as quadratic and degree 3 is called as cubic. A curve with degree 1 is called as linear curve, with degree 2 It is the measure of curvature of the curve. Actually itвЂ™s just a sequence of some real numbers, in non-decreasing order. In this case nurbs-calculator will be very useful for you.ДЄ NURBS curve can be created by just 3 parameters вЂ“ degree, control point and knot vector. Have to write your own programs or use some commercial CAD softwares, which is a lot of overhead, just to NURBS, until you do a practical, by creating some curves and modifying the parameters. This is a very good course to start, but the problem is that you canвЂ™t understand all the properties of If you are not new to NURBS, then you might have read the theory of NURBS from this website.

Modify the curve parameters from your mobile/ tablet/ laptop browser.

You full control on all the curve parameters, then nurbs-calculator is for you. If you just want to work with NURBS curves and looking for a small tool, which gives Also some of these softwares donвЂ™t allow users to changeДЄll the NURBS parameter. There are a lot of CAD softwares in which you can create NURBS curves, like Autodesk Maya, Rhinoceros 3D and SolidWorks But these softwares require installation onДesktop PCвЂ™s and consume a lot of computer resources. Splines and freeform curves have a lot of usage in designing of machine part, ship building and gaming.
