Feature-preserving T-mesh construction using skeleton-based polycubes ?
We present a novel algorithm which uses skeleton-based polycube generation to construct T-meshes. Three kinds of features are preserved: open curves, closed curves, singularity features. With a valid T-mesh, we calculate trivariate T-splines for isogeometric analysis.
