We propose a new method for generation of quadrilateral meshes. Our algorithm takes a triangle mesh generated on a computer-aided design surface together with a size field as input. A novel cross field, defined on vertices of the triangle mesh, is derived from both curvature directions and constraints on the boundary. Our algorithm uses a modified QMorph algorithm for quad dominant meshing, to follow size field and to align edges with the cross field previously computed.
