mayavi mlab get current axes
What you are expecting to be able to do from your matplotlib experience is not how mayavi axes work.  In matplotlib the visualization is a child of the axes and the axes determines its coordinates.  In mayavi or vtk, visualization sources consist of points in space.  Axes are objects that surround a source and provide tick markings of the coordinate extent of those objects, that are not necessary for the visualizations, and where they exist they are children of sources.
Is there a way of a procedure similar to plt.gca() to get a handle to the current axes. I first do a=mlab.surf(x, y, u2,warp_scale='auto')
and then
b=mlab.plot3d(yy, yy, (yy-40)**2 ,tube_radius=20.0)
but the origin of a and b are different and the plot looks incorrect. So I want to put b into the axes of a
In short, what would be the best way in mayavi to draw a surface and a line on same axes?
