boundary Struct Reference

Detailed Description

Struct that defines the boundary sides and corners and types of a geometric object.

These definitions are used by, e.g., boxSide, boxCorner, etc.

The sides are numbered as follows:

2D CASE	3D CASE
Edge 1, {(u,v) : u = 0} : west	Face 1, {(u,v,w) : u = 0}: west
Edge 2, {(u,v) : u = 1} : east	Face 2, {(u,v,w) : u = 1}: east
Edge 3, {(u,v) : v = 0} : south	Face 3, {(u,v,w) : v = 0}: south
Edge 4, {(u,v) : v = 1} : north	Face 4, {(u,v,w) : v = 1}: north
	Face 5, {(u,v,w) : w = 0}: front
	Face 6, {(u,v,w) : w = 1}: back

none is a special compatibility value used to denote that this is not a boundary.

The corners are numbered as follows:

2D CASE	3D CASE
Corner 1, {(u,v) : u = 0, v = 0} : southwest	Corner 1, {(u,v,w) : u = 0, v = 0, w = 0}: southwestfront
Corner 2, {(u,v) : u = 1, v = 0} : southeast	Corner 2, {(u,v,w) : u = 1, v = 0, w = 0}: southeastfront
Corner 3, {(u,v) : u = 0, v = 1} : northwest	Corner 3, {(u,v,w) : u = 0, v = 1, w = 0}: northwestfront
Corner 4, {(u,v) : u = 1, v = 1} : northeast	Corner 4, {(u,v,w) : u = 1, v = 1, w = 0}: northeastfront
	Corner 5, {(u,v,w) : u = 0, v = 0, w = 1}: southwestback
	Corner 6, {(u,v,w) : u = 1, v = 0, w = 1}: southeastback
	Corner 7, {(u,v,w) : u = 0, v = 1, w = 1}: northwestback
	Corner 8, {(u,v,w) : u = 1, v = 1, w = 1}: northeastback
