hexahedron2, hexahedron3
Purpose
hexahedron2, hexahedron3
Create bilinear hexahedron geometry object.
Syntax
Description
h2 = hexahedron2(p)
h3 = hexahedron3(p)
h3 = hexahedron3(p) creates a solid hexahedron object with corners in the 3D
coordinates given by the eight columns of p. hexahedron3 is a subclass of solid3.
h2 = hexahedron2(p) creates a surface hexahedron object with corners in the 3D
coordinates given by the eight columns of p. hexahedron3 is a subclass of face3.
For a hexahedron approximately aligned to the coordinate planes, the points in p
are ordered as follows. The first four points and the last four points projected down
to the (x,y)-plane defines two negatively oriented quadrangles. The corresponding
plane for the second quadrangle must lie above the plane of the first quadrant in the
z-direction. Generally oriented hexahedra have the points of p ordered in a similar
way, except for a rigid transformation of the defining point set.
The default value of p is
p=[0 0 1 1 0 0 1 1;
0 1 1 0 0 1 1 0;
0 0 0 0 1 1 1 1]
The 3D geometry object properties are available. The properties can be accessed
using the syntax get(object,property). See geom3 for details.
Example
The following command generates a solid hexahedron object.
h3 = hexahedron3([0 0 1 1 0 0 1 1;...
0 0.8 1 0 0 1 1.2 0;...
0 0.1 0 0.2 1 1 2 1]);
