Description:
|
Checks for the presence of patterns on the BODY, LUMPs, SHELLs, FACEs, and LOOPs of an entity and generates a list of the elements with patterns. Returns
#t when elements with patterns exist and
#f when there are no elements with patterns.
|
|
|
entity specifies an entity.
|
|
|
Defining
type-list ('bodies, 'lumps, 'shells, 'faces, or 'loops) generates a more selective check. By default, the function checks all entities.
|
|
|
If
color is specified as #t, the faces, edges, and vertices that are patterned are colored in the display.

command.

(define s (solid:sphere (position 0 0 0) 10))
|
|
;; s
|
|
; Define a 2x2 hex pattern.

(define p (pattern:hex (gvector 0 1 1)

|
|
(gvector 40 0 0) 2 2))
|
|
;; p
|
|
; Create an entity using sphere in the pattern.

|
(define hexpat (entity:pattern s p))
|
|
;; hexpat
