One Basis to Animate Them All: Gaussian Blendshape Distillation for Real-Time Avatars
Making 3D avatars animate faster by simplifying how they move
Researchers found that 3D avatars can be animated using simple math instead of heavy neural networks, cutting animation processing by up to 1,000 times. Their method, called GALA, replaces complex per-frame computations with a lightweight predictor and linear blending, achieving 60 frames per second on mobile phones while keeping visual quality nearly intact.
Real-time 3D avatars for video calls, games, and virtual meetings currently require significant computing power. This method brings high-quality avatar animation to mobile devices and low-end hardware, making lifelike digital representations accessible for everyday applications rather than just high-end workstations. The 1,000-fold speed improvement means smoother, faster interactions with minimal lag.
