8.33 solids
This solid geometry package defines a structure revolution that
can be used to fill and draw surfaces of revolution. The following example
uses it to display the outline of a circular cylinder of radius 1
with axis O--1.5unit(Y+Z) with perspective projection:
import solids; size(0,100); revolution r=cylinder(O,1,1.5,Y+Z); draw(r,heavygreen);
Further illustrations are provided in the example files cylinder.asy,
cones.asy, hyperboloid.asy, and torus.asy.
The structure skeleton contains the three-dimensional wireframe
used to visualize a volume of revolution:
struct skeleton {
struct curve {
path3[] front;
path3[] back;
}
// transverse skeleton (perpendicular to axis of revolution)
curve transverse;
// longitudinal skeleton (parallel to axis of revolution)
curve longitudinal;
}
