We present a design space explorer for the space of experimental designs. For many design problems, design decisions are determined by the consequences of the design rather than its elemental parts. To support this need, the explorer is constructed to make the designer aware of design-level options, provide a structured context for design, and provide feedback on the consequences of design decisions. We argue that this approach encourages the designer to consider a wider variety of designs, which will lead to more effective designs overall. In a qualitative study, experiment designers using the explorer were found to consider a wider variety of designs and more designs overall than they reported considering in their normal practice.

The construction and processing of surface geometry can be done by connecting surface primitives to vertices, edges, and neighbors. The representation schemes of surface geometry are vertex-based, edge-based, and quad-edge-based. Catmull and Clark rule of subdivision includes three different rules to create new vertices in the refined control mesh, that are vertex, edge, and face subdivision rule. A new vertex can be created in the refined mesh as a convex combination of the vertices in the neighborhood of vertex, edge, and face in the control mesh. The first subdivision step has a quadrangle control mesh and number of vertices with valence unequal to four constant during refinement. The Charles Loop subdivision scheme is based on box spline and during a subdivision a triangle is divided into four triangles through vertex and edge subdivision rule.
