Sometimes the curve will have two ends sometimes the two ends of the curve will actually be the same point - i.e.the two ends of the string are taped together. If you like, you could think of a curve as a piece of string that's sitting in two- or three-dimensional space.Įxamples are a segment of a straight line, a circle, or a section of any graph of a function. The term "curve" has not been defined yet, but roughly speaking,a curve (or an "arc") is a curvy line in space. This week we will consider parametric equations of curve. These skills will be very important later in this class,which is why we're spending so much time on them now. Instead, it's about visualizing and describing different curves and surfaces. Some parallelization helps speed up the drawing of text on a surface.Questions to: than a short bit about derivatives at the end of this notebook, Lab 2 is almost entirely devoid of calculus. : added code to take care of the case when two font characters overlap (which is not so unusual), a situation that wreaked havoc in the previous version when drawing them onto a curved surface the workaround may not work with complicated overlaps, but these should be rare. The functions are the same for the user, but the underlying code is new, and the performance is much better. : I take advantage of the new computational geometry features of Mathematica version 10 to give a (finally!) satisfactory support for drawing polygon and text on a curved surface. : fixed and improved TextToGraphics and TextToGraphics3D. : added compatibility with PlotLegends of version 9. LinearPhasePlot2D is back in working order. Turned off the warning messages about unknown options in Plot etc. Added new mechanisms so that the shape of 3D arrow cones should not be affected by the value of BoxRatios. : added the new options HeadProportion3D and HeadScalingTransform3D, and deleted obsolete references to HeadWidth3D. : restored the functionality of TextToGraphics, TextToGraphics3D and text on a surface to Mathematica version 8. : fixed some bugs involving Oriented, ColorFunction, ReverseOrientation, ArrowShaftLength, Arrowheads. : added support for ColorFunction in Oriented. : added support for Tube objects as an alternative to Line in 3D. : removed obsolete references to pre-Mathematica 6 CurvesGraphics code, and added a new example. : With Mathematica version 7 or later you can now use the Oriented option with BSplineCurve too. : With Mathematica version 7 you can now use the Oriented option with ListCurvePathPlot and ListLinePlot too. : With Mathematica version 7 the package now uses the Cone primitive to draw 3D arrows, and it can map StreamPlots onto a surface.
