AnimationDiff: A Visual Comparison Tool for Generated 3D Character Animations
For animators and researchers dealing with multiple generated animations, this tool addresses the challenge of comparing temporally misaligned spatial data.
AnimationDiff is a visual comparison tool for generated 3D character animations that enables contextual comparisons with overlaid and side-by-side views, filtering, and Temporal Lenses. A user study demonstrated its efficacy in animation comparison.
Creating 3D character animations traditionally requires significant time and effort from the animator. Advancements in generative methods now enable easy creation of multiple character animation variations for use or further editing. However, this capability introduces a new challenge in comparing character animations to select the best animation, which is challenging due to temporal misalignment and the large amount of spatial data. We present AnimationDiff, a visual comparison tool for generated character animations. AnimationDiff enables contextual comparisons in the intended scene and camera angle, and embedding of spatial information by combining established animation visualization techniques and easy switching between overlaid and side-by-side comparisons. AnimationDiff also supports filtering to handle information overload, and Temporal Lenses that visualize entire animations over time for overview, alignment, and comparison. We evaluated AnimationDiff in a user study, showcasing its efficacy in animation comparison and providing design insights for comparing motion.
