Real-time goal space steering for data-driven character animation

摘要

A method for generating real-time goal space steering for data-driven character animation is disclosed. A goal space table of sparse samplings of possible future locations is computed, indexed by the starting blend value and frame. A steer space is computed as a function of the current blend value and frame, interpolated from the nearest indices of the table lookup in the goal space. The steer space is then transformed to local coordinates of a character's position at the current frame. The steer space samples closest to a line connecting the character's position with the goal location may be selected. The blending values of the two selected steer space samples are interpolated to compute the new blending value to render subsequent frames of an animation sequence.
