brep_simple(1)

NAME

brep_simple - constructs a simple boundary representation (b-rep) twisted cube

SYNOPSIS

brep_simple

DESCRIPTION

brep_simple constructs a simple b-rep twisted cube directly using the openNURBS API. The constructed twisted cube is written to a geometry database (brep_simple.g) using the wdb interface. The cube is constructed by first defining and creating the vertices, then the twisted edges (using trimming curves), and finally the faces to get a final topology like the following:

                       H-------e6-------G
                      /                /|
                     / |              / |
                    /  e7            /  e5
                   /   |            /   |
                  /                e10  |
                 /     |          /     |
                e11    E- - e4- -/- - - F
               /                /      /

             |     /          |     /
             |    e8          |    /
             e3  /            e1  /
