psbody示例

target_mesh = Mesh(filename=template_file)
target_mesh.set_vertex_colors('white')
viewer = MeshViewer()
# viewer.set_background_color((1.0, 1.0, 1.0),blocking=False)
viewer.set_static_meshes([target_mesh], blocking=True)
# viewer.set_dynamic_meshes(target_mesh)
viewer.set_background_color((1.0, 1.0, 1.0))
viewer.show()
这个显示是黑屏,不能显示物体
trimesh加载
FaceDiffuser
python
import trimesh
if __name__ == '__main__':
template_file=f"data/BIWI/templates/face_template.obj"
ref_mesh = trimesh.load_mesh(template_file, process=False)
scene = trimesh.scene.scene.Scene([ref_mesh])
# 显示场景
scene.show()
报错:
python
ImportError: `trimesh.viewer.windowed` requires `pip install "pyglet<2"`
解决方法:
pip install "pyglet<2"
加载动画:
python

# 假设嘴角的顶点索引已知
mouth_corner_indices = [1500, 2300] # 示例索引,需要根据实际模型调整
movement = np.array([0, intensity, 0]) # 向上移动
for idx in mouth_corner_indices:
