Velocity Skinning for Real‐time Stylized Skeletal Animation

Abstract

Figure 1: Left: Skeletal rig, with a single bone in the head: When animated using velocity skinning, secondary animation effects are automatically added to the ear, and face, while the horn can be set as rigid. Right: The native efficiency and simplicity of the method is compatible with GPU implementation used to compute thousands of animated cows in real-time.

SMEAR: Stylized Motion Exaggeration with ARt-direction

“…Geometric deformers based on bone velocities [Noble and Tang 2007;Rohmer et al 2021] and accelerations [Kalyanasundaram et al 2022] are able to reproduce a wide range of motion exaggeration effects, and offer artist control through painted weights and handles. Example-based methods [Dvorožňák et al 2017;Roberts and Mallett 2013] provide even more natural and intuitive controls, but they must be set up manually for each specific animation.…”

“…Full skeleton. For a vertex 𝑖 affected by multiple bones, its motion offset is computed by the contribution of each bone 𝑘 through its skinning weight 𝑤 𝑖𝑘 , similarly to [Rohmer et al 2021…”

Procedural Methods for Skinning Humanoid Characters

“…Один из предлагаемых вариантов подразумевает добавление вторичных эффектов поверх стандартного скиннинга, что позволит стилизовать движение модели под руководством художника [32].…”
