Description:
|
Creates a sphere centered at the specified position.
center-position specifies the center position of the sphere. There are two syntax formats available for defining the
center-position. The first (original) syntax format defines the
center-position by placing the
xyz coordinates in a 'position' statement enclosed in parenthesis (as shown in the example below with creating sphere1). However, the second syntax format defines the center position
xyz coordinates without using the 'position' statement or the additional set of parenthesis (as shown in the example below with defining sphere2 and sphere3). The two formats are otherwise identical.
|
|
|
center-position specifies the center position of the sphere
|
|
|
center-x,
center-y,
center-z is the syntax for the positional argument
center-position.
|
|
|
radius determines the size of the sphere.
|
|
|
Example:
|
; solid:sphere
|
|
; Create first sphere. Use 'position' syntax format
|
|
; for defining the positions.
|
|
; Create solid sphere1.
|
|
(define sphere1
|
|
|
(solid:sphere (position -4 -4 0) 1.5))
|
|
;; sphere1
|
|
; Create 2nd sphere.Use alternate position argument
|
|
; format. Define radius.
|
|
(define sphere2
|
|
|
(solid:sphere -30 0 0 15))
|
|
;; sphere2
|
|
; Create solid sphere 3.
|
|
; Define 2nd sphere using alternate position argument
|
|
; format. Define radius.
|
|
(define sphere3 (solid:sphere 10 10 10 5)))
|
|
;; sphere3
