Abstract
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.
Claims24
A method for rendering one or more frames of an animated character, the method comprising:
- determining a current blending value used to blend frames from at least two motion clips in rendering a current fame, wherein the two motion clips are selected from a plurality of motion clips forming a motion space, and wherein each of the plurality of motion clips corresponds to an instance of a given motion performed by the character at a different turning rate;
- and
- selecting, based on the current blending value and a goal location, a new blending value to render the animated character in a subsequent frame, wherein the new blending value steers the character towards the goal location.
A computer-readable storage medium storing instructions that when executed by a processor cause the processor to perform an operation for rendering one or more frames of an animated character, the operation comprising:
- determining a current blending value used to blend frames from at least two motion clips in rendering a current fame, wherein the two motion clips are selected from a plurality of motion clips forming a motion space, and wherein each of the plurality of motion clips corresponds to an instance of a given motion performed by the character at a different turning rate;
- and
- selecting, based on the current blending value and a goal location, a new blending value to render the animated character in a subsequent frame, wherein the new blending value steers the character towards the goal location.
A system, comprising:
- a processor;
- and
- a memory storing one or more application programs, which, when executed on the processor perform an operation for rendering one or more frames of an animated character, the operation comprising:
- determining a current blending value used to blend frames from at least two motion clips in rendering a current fame, wherein the two motion clips are selected from a plurality of motion clips forming a motion space, and wherein each of the plurality of motion clips corresponds to an instance of a given motion performed by the character at a different turning rate, and
- selecting, based on the current blending value and a goal location, a new blending value to render the animated character in a subsequent frame, wherein the new blending value steers the character towards the goal location.
