在mayavi中是否可以分别指定每个点的大小和颜色？

该API对我来说很麻烦。

points3d(x, y, z...)
points3d(x, y, z, s, ...)
points3d(x, y, z, f, ...)

x, y and z are numpy arrays, or lists, all of the same shape, giving the positions of the points.
If only 3 arrays x, y, z are given, all the points are drawn with the same size and color.
In addition, you can pass a fourth array s of the same shape as x, y, and z giving an associated scalar value for each point, or a function f(x, y, z) returning the scalar value. This scalar value can be used to modulate the color and the size of the points.

因此，在这种情况下，标量会同时控制大小和颜色，并且无法解开它们。我想要一种将大小分别指定为(N,1)数组并将颜色分别指定为另一个(N,1)数组的方法。

看起来复杂吗？
