BREP_SIMPLE(1) BRL-CAD User Commands BREP_SIMPLE(1)

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

brep_simple

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:
