Nettet28. jun. 2024 · We feed the output of the attention mesh submodels to this blend shape network. In order to handle differences be- tween various human faces, we apply Laplacian mesh edit- ing to morph a canonical mesh into the predicted mesh [3]. This lets us use the blend shape coefficients for different hu- man faces without additional fine-tuning. Nettet17. sep. 2024 · Blend shapes are also commonly used for facial animation, with different blend shapes representing different motions of the facial muscles, such as raising/lowering eyebrows, squinting the eyes, flaring the nostrils, moving the lips in various ways, etc. These are very difficult to model realistically using linear-blend skinning alone.
