In this paper we draw the attention to a new way of computing such constrained quad meshes. The new methodology is based on the diagonal meshes of a quad mesh and the checkerboard pattern of parallelograms one obtains by subdividing a quad mesh at its edge midpoints.

We discretize isometric mappings between surfaces as correspondences between checkerboard patterns derived from quad meshes.

Motivated by analogies to classical differential geometry, we propose a theory of smoothness of polyhedral surfaces including suitable notions of normal vectors, tangent planes, asymptotic directions, and parabolic curves that are invariant under projective transformations.

In this paper we study pleated structures generated by folding paper along curved creases. We discuss their properties and the special case of principal pleated structures.

Checkerboard patterns with black rectangles can be derived from quad meshes with orthogonal diagonals.

In this paper, we introduce an effective way of limit analysis on the bearing capacity of given trusses.

We present a novel isotropic surface remeshing algorithm that automatically aligns the mesh edges with an underlying directional field.

We study the design and optimization of polygonal meshes with concave planar faces.
