Hi all,

I have a 2D matrix, which has 100 rows, and 100 columns,

I have a 2D matrix, with 100 rows and 100 columns,

I want to display it using 3D plot, much like plot3d and mesh/surf functions
in matlab.

Specifically, in matlab, I just need to do the following:

--------
[X, Y]=meshgrid([0:0.01:0.99, 0:0.01:0.99]);
% Z is my 2D matrix,
surf(X, Y, Z);
--------

Note that X and Y are created so that I can associate physical meaning onto
the x and y axis of the 3D plot.

For example, my 100 rows represent 0, 0.01, 0.02, ... 0.99 here.

In Matlab I can also drag in the graphic window and see from different
visual angle and perspective of the 3D plot...

Are there similar functions in R that (1) show 3D plot; (2) let me
manipulate view angles easily?

Thanks a lot!
