Instructions
The following images were taken from the app and the instructions in parentheses only work in the app.
The vectors of the initial Frenet-Serret frame are marked in green:
- T - Tangent
- N - Normal
- B - Binormal
The red curve has curvature and torsion given by the functions below.
(Move the red point to choose the Frenet-Serret frame at instants Si.)
(Move these points to draw the curvature function.)
Indication whether the red curve is in a plane or not.
(Move the upper points to choose the initial Frenet-Serret frame and move the lower point to zoom the curve.)
(Move these points to draw the torsion function.)
