Description: A spherical-face is a topological entity that is a face that is spherical in nature. A face is a topological entity that is a portion of a single geometric surface. A face records its sense relative to its underlying surface (same sense or opposite sense). spherical-face objects are saved and restored as part of the model.

Derivation: spherical-face : face : entity : scheme-object

C++ Type: FACE->SPHERE

External Rep: #[entity %d %d]

where the first integer is the entity ID,

and the second integer is the part ID.

Example: ; spherical-face (data type)

; Create and inquire a spherical-face object.

(define my_sph (solid:sphere (position 0 0 0) 20))

;; my_sph

(define my_faces (entity:faces my_sph))

;; my_faces

(face:spherical? (car my_faces))
