This file contains macros for segments of shapes, facetted shapes and others.

Segments of shapes:

Segment_of_Torus ( R_major, R_minor, Segment_Angle )

Segment of a torus around the y axis. The angle starts at positive x axis.

Segment_of_CylinderRing ( R_out, R_in, Height, Segment_Angle )

Segment of a cylindrical ring around the y axis. The angle starts at positive x axis.

Segment_of_Object ( Segment_Object, Segment_Angle )

Segment of an object around the y axis. The angle starts at positive x axis.
Based on min_extend and max_extend.

Angular shapes:

Column_N (N, R_in, Height )

A regular n-sided column around the y axis, defined by the incircle radius R_in. Height is the height in y direction.

Column_N_AB (N, A, B, R_in)

A regular n-sided column from point A to point B, defined by the incircle radius R_in.

Pyramid_N (N, R_in_1, R_in_2, Height )

A regular n-sided pyramid around the y axis, defined by the incircle radii:
R_in_1 at y = 0 and R_in_2 at y = Height.

Pyramid_N_AB(N, A, R_in_A, B, R_in_B)

A regular n-sided column from point A to point B, defined by the incircle radii:
R_in_A at point A and R_in_B at point B.

Facetted shapes:

Facetted_Sphere (Quarter_Segments, Radial_Segments)

A facetted sphere with incircle radius 1.
Quarter_Segments = number of equitorial facetts in one quarter (1/2 of the total number).
Radial_Segments = number of radial facetts.

Facetted_Egg_Shape (Quarter_Segments, Radial_Segments, Lower_Scale, Upper_Scale)

A facetted egg shape. The number of facetts are defined analog to Facetted_Egg_Shape().
Equitorial incircle radius = 1. Lower half scaled in y by Lower_Scale, Upper half scaled in y by Upper_Scale.

Facetted_Egg (N_Quarter_Segments, N_Radial_Segments)

A facetted egg with total height = 2. Lower half scaled in y by 1.15, Upper half scaled in y by 1.55.

Round shapes:

Egg_Shape (Lower_Scale, Upper_Scale)

An egg shape with equitorial radius 1.
Lower half scaled in y by Lower_Scale, Upper half scaled in y by Upper_Scale.

Egg

Uses the macro Egg_Shape.
Lower half scaled in y by 1.15, upper half scaled in y by 1.55.

Wireframe shape (mostly also optionally filled:

Ring_Sphere (Rmaj_H, Rmaj_V, Rmin_H, Rmin_V, Number_of_Rings_horizontal, Number_of_Rings_vertical)

A wireframe sphere by vertical and horizontal torii.
Horizontal tori: equatorial radius major Rmaj_H, radius minor Rmin_H.

The radius of the lower part is R_lower, the radius of the lower part is R_lower The minor radius of the toroid is R_border.

Round_Conic_Prism( Center_Distance, R_upper, R_lower, Length_Zminus, R_Border, Merge)

A shape of the toroidal form like Round_Conic_Torus(), but filled and in the negativ z direction with the length Length_Zminus.

Half_Hollowed_Rounded_Cylinder1( Length, R_out, R_border, BorderScale, Merge)
