Curve Stitching on Splines with Rotations
Loading the math board and drawing, please wait…
This example demonstrates curve stitching on splines incorporating rotation transformations. It involves core math concepts like rotation, matrices, rectangles, tangent functions, and congruence. Constructed using GeoGebra commands like Spline and Sequence, it's suitable for high school geometry education or exploratory activities on parametric curves and transformations.
GeoGebra Commands & Parameters
Spline({C, E, D}, 3) → bSpline({A, B, C}, 3) → aSequence(Segment[a(w), b(w)], w, 0, 1, 1 / 40) → L_3Sequence(Rotate[L_3, ((w * 2) * π / n)], w, 1, n) → L_1
AI Drawing Prompt Reference
Draw a region bounded by two cubic spline curves, one passing through three points forming a smooth arc, the other connecting three different points. Between the two splines, generate a series of connecting segments at equal intervals, each linking a point on the first spline to a corresponding point on the second. Then rotate the entire set of these segments around a central point, with rotation angles increasing by equal divisions of a full circle, creating multiple radial groups of lines that form a symmetric, rhythmic curve-stitching pattern.
