Description
Aiming at applications in architectural design of freeform
glass structures, we introduce conical meshes as a new type of
quadrilateral meshes which discretize the network of principal
curvature lines. Unlike any other mesh representation, conical
meshes have a natural offsetting operation and provide a support
structure orthogonal to the mesh. We address relations to Laguerre
geometry, to developable surfaces, and discuss their computation
with a technique combining optimization and subdivision.
