Sculptured surface synthesis based on functional design constraints

摘要: A technique is presented for the synthesis of sculptured surface models subject to several functional design constraints. environment specified as a collection polyhedral which represent components in vicinity surface, or regions should avoid. The primary constraint formulated proximity penalty function such that induced avoid tolerance envelope around each component. In addition, based on area counteract expansion effect constraint. Secondary constraints are maintain consistent topology, and exploit part symmetry. Surface thus an optimization problem solved via simulated annealing. Several example applications demonstrate capabilities technique.
