为Mayavi对象TVTK对象设置动画

Question

我有一个可视化对象的脚本，我需要为它设置动画。但我使用的是TVTK Polydata对象，似​​乎我无法使用mlab_source技术更改Polydata的标量变量。

请让我知道如何通过更改PolyData的标量来设置动画。 感谢

def polydata(pointsList, triangleList, scalars):
    points = numpy.array(pointsList, 'f')
    triangles = numpy.array(triangleList)
    mesh = tvtk.PolyData(points=points, polys=triangles)
    mesh.point_data.scalars = scalars
    mesh.point_data.scalars.name = 'scalars'
    return mesh 

def view(dataset):
    fig = mlab.figure(bgcolor=(1, 1, 1), fgcolor=(0, 0, 0),
    figure=dataset.class_name[3:])
    m_surf = mlab.pipeline.surface(dataset, opacity=1)
    return m_surf

m_surf = view(polydata(pointsList, triangleList, FMRIValues_norm[0]))
ms = m_surf.mlab_source #Gives the error.
