%DRAWBOX3D Draw a 3D box defined by coordinate extents.

% drawBox3d(BOX);
% Draw a box defined by its coordinate extents:
% BOX = [XMIN XMAX YMIN YMAX ZMIN ZMAX].
% The function draws only the outline edges of the box.
%
% Example
% % Draw bounding box of a cubeoctehedron
% [v e f] = createCubeOctahedron;
% box3d = boundingBox3d(v);
% figure; hold on;
% drawMesh(v, f);
% drawBox3d(box3d);
% set(gcf, 'renderer', 'opengl')
% axis([-2 2 -2 2 -2 2]);
