Draw3d

Function: draw3d (<option>, <graphic_object>, ...) This function is a short cut for draw(gr3d(<options>, ..., <graphic_object>, ...)).

r(t) := [10*cos(t),2*sin(t),t];
r(4);
float(r(4));
load(draw);
draw3d(color=magenta,parametric(-cos(t), sin(t),cos(t), t,-4, 4));
define(rp(t), diff(r(t), t));
float(rp(1));
load(eigen);
uvect(rp(t));
trigsimp(rp(t));
define(T(t), trigsimp(rp(t)));
define(Tp(t), diff(T(t), t));
uvect(Tp(t));
trigsimp(uvect(Tp(t)));
define(N(t), trigsimp(uvect(Tp(t))));

It can be used to plot a unique scene in 3d.

To make use of this function, write first load(draw).

See also draw and gr3d.
