Dear users,
I would like to do the following, using Maple7:
Given a sequence of x,y,z-data points (which are organized so they can be
plotted with sufdata), create a surface plot looking like a mountain _and_
in the xy-plane of the same plot have the countour lines of this data.
The contours should show up as projections into the xy-plane.
I know how to get the surface:
surfdata(data, axes=frame, orientation=[70,30])
^^
and I know how to get the contour lines:
surfdata(data, axes=frame, style=contour, orientation=[70,0]);
^^
But how do I combine this into a nice 3D picture?
Thanks a lot in advance,
Jens

The "orientation=[70,0]" trick does not really project anything (rotate
that plot with the mouse!).
Instead, visit the Maple Application Center (http://www.mapleapps.com),
enter contour as the search term, and take a look at the "Contourplot in
3D space" worksheet. The dropshadowplot procedure expects an expression
as its first argument, but could be adapted to your needs.
It also demonstrates how to combine graphs using the display command.
