CURVE APPROXIMATING ALGORITHM FOR QUICKLY FORMING PROFILE LINE CORRESPONDING TO STROKE

摘要

PURPOSE: To further speedily generate two lines separated with an equal distance at the both sides of an original orbit. CONSTITUTION: This method is provided with a first step for deciding whether or not a parazoid appropriately approximates a masked stroke. If not, an algorithm recursively subdivides an orbit until each segment fulfills tests. A second step is an algorithm for directly calculating the parazoid equivalent to each segment.
