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 pointB
, defined by the incircle radiusR_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 andR_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 pointB
, defined by the incircle radii:
R_in_A
at pointA
andR_in_B
at pointB
.
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 byLower_Scale
, Upper half scaled in y byUpper_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 byLower_Scale
, Upper half scaled in y byUpper_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 majorRmaj_H
, radius minorRmin_H
