Performance-Guided Character Bind Pose for Deformations
MetadataShow full item record
Current production methods for creating a motion system for a deformable digital character model involve providing an underlying joint structure based o of a T-Pose, A-Pose or another arbitrary bind pose of the character. A bind pose is required to establish the skeleton-to-geometry spatial relationship that will be used as a mathematical reference to determine geometry deformations in animated poses. Using a set of human motion capture performances as input animation, the impact of the standard T-Pose and A-Pose on the stretching and compression of human character model geometry is compared relative to novel mean poses derived from each performance. Results demonstrate that using an averaged joint position of each specific performance as the bind pose for the performance reduces the overall deformation of the model. Appropriate applications of the mean pose as a bind pose could impact the resources required to repair deformation artifacts in animated deformable digital characters.
