ABSTRACT:
A graphic structure having joint angles is manipulated from an initial configuration towards a goal configuration by a succession of iterations, in each of which an update configuration is derived from a prior configuration. A regular iteration determines at least one test configuration by modifying fewer than all of the joint angles of the prior configuration, determines, for each test configuration, an improvement value reflecting the improvement between the differences of the prior configuration and the test configuration with respect to the goal configuration, and selects a test configuration as the updated configuration based on the improvement values.
