Library - solids
Library solids implements functions which create solid shapes in 3D. Solids are generated with parametric equations and displayed with surf. When called without output argument, with an optional trailing string argument for the edge style, the solid is displayed with the current scaling and color map. With output arguments, arrays X, Y, Z expected by surf or mesh are produced. They can be modified to move, scale or stretch the solids.
The following statement makes available functions defined in solids:
use solids
Functions
cone
Cone.
Syntax
use solids cone cone(cap) cone(cap, n) cone(cap, n, style) (X, Y, Z) = cone (X, Y, Z) = cone(n)
Description
Without output argument, cone draws a cone approximated by a polyhedron. The optional first input argument, a logical value which is true by default, specifies if the cap is included. The optional second input argument, an integer, specifies the number of discrete values for the parameter which describes its surface.
By default, edges are not drawn. An optional third input argument, a string, specifies the edge style; it corresponds to the style argument of surf.
With three output arguments, cone produces the X, Y, and Z arrays expected by surf or mesh, and it does not display anything.

crosscap
Cross-cap.
Syntax
use solids crosscap crosscap(n) crosscap(n, style) (X, Y, Z) = crosscap (X, Y, Z) = crosscap(n)
Description
Without output argument, crosscap draws a cross-cap (a self-intersecting surface) approximated by a polyhedron. With an input argument, crosscap(n) draws a cross-cap where the two parameters which describe its surface are sampled with n discrete values.
By default, edges are not drawn. An optional second input argument, a string, specifies the edge style; it corresponds to the style argument of surf.
With three output arguments, crosscap produces the X, Y, and Z arrays expected by surf or mesh, and it does not display anything.

Syntax
use solids klein klein(p) klein(p, n) klein(p, n, style) (X, Y, Z) = ...
Description
Without output argument, klein draws a Klein bottle approximated by a polyhedron. With an input argument, klein(p) uses parameters stored in structure p. The following fields are used:
Field | Description | Default value |
---|---|---|
r0 | average tube radius | 0.7 |
d | tube variation | 0.5 |
h | half height | 3 |
With two input arguments, klein(p,n) draws a Klein bottle where the two parameters which describe its surface are sampled with n discrete values.
By default, edges are not drawn. An optional third input argument, a string, specifies the edge style; it corresponds to the style argument of surf.
With three output arguments, klein produces the X, Y, and Z arrays expected by surf or mesh, and it does not display anything.

Description
Without output argument, klein8 draws a figure 8 Klein bottle immersion (a closed, self-intersecting surface with one face) approximated by a polyhedron. With an input argument, klein8(r) draws the surface with a main radius of r (the default value is 1).
With two input arguments, klein8(r,n) samples the two parameters which describe its surface with n discrete values.
By default, edges are not drawn. An optional third input argument, a string, specifies the edge style; it corresponds to the style argument of surf.

With an input argument, sphericon(n) draws a sphericon where the two parameters which describe its surface are sampled with n discrete values.
