摘要:
A method optimizes a system. Performances of design parameters of an objective function modeling the system are represented in a multi-dimensional search space. A set of vertices are positioned in the search space. Each vertex has an associated one of the performances. The vertices in the set are sorted in a worst to best performance order. Each vertex in the ordered set is moved to a next position if the performance at the next position is better than a current performance of the vertex. The sorting and moving are repeated in a cycle until a termination condition is reached.

A method edits a graphics object by first representing the graphics object by an adaptively sampled distance field. A portion of the adaptively sampled distance field is selected for editing and converted to a triangle model. The triangle model is then deformed, the adaptively sampled distance field is regenerated from the deformed triangle model.
摘要:
A method edits a graphics object with a computer implemented tool by first representing the graphics object by an adaptively sampled distance field, and defining a mask by a distance field. Then, the tool is iteratively moved with respect to the object while constraining the movement according to the mask to edit the object.
