In conceptual design of models, designers usually express their ideas in curve networks, without generating final 3D surfaces. In this paper, we propose a method to utilize the structures and properties of curve netwo...

Volumetric mesh models are widely used nowadays in areas like product quality evaluation, physically-based deformation, numerical simulation, and so on. In the application of computeraideddesign (cad) and computer A...
详细信息
the representation of triangular mesh surface is proposed using spherical image. Surface signals like normals and curvatures are stored in spherical images using spherical parameterization and partition of the sphere....
