Hello,

I want to draw contour maps from a two dimensional matrix of scalar values.
I am not an expert in graphics techniques and am unfamiliar with basic
concepts and the literature. This is for a limited project and I do not want
to become an expert. The routines need to be modestly sophisticated since
the data is somewhat noisy, fairly in places and can have several peaks and
troughs. Typical arrays are 4000 rows by 40 columns and span values +- 60
arbitrary units.

Can anyone point me at or supply me with a subroutine or group of subroutines
that can scan a matrix and generate a series of x-y pairs that I can feed to
my graphic routines to draw a contour map of the data?

I am working on VMS so I can link from my C routines to functions written in
FORTRAN, C, PASCAL, BASIC, or VMS-ASSEMBLER. FORTRAN or C would be better for
me since I know these languages fairly well and could adapt them for my
purposes.

I am not a subscriber to INFO-GRAPHICS so please send any responses to one of
the addresses listed below. Thank you.

ABSTRACT - The dark ages of black-and-white lines at NYU. How
the University of Utah did it with no equipment. How Xerox PARC
kissed off color graphics but got an Emmy anyway. How Alex
Schure met Ivan Sutherland and begat NYIT. How Evans & Sutherland
succeeded & failed. How Siggraph grew up. The sad story of
standards. The amazing stories of NYIT: Los Ricos National
Forest, "make Tubby dance", Holloway house. Who said, "Our goal
is to speed up time, eventually deleting it"? David Em unmasked
(the M is revealed). Jim Blinn dances. Video art vs computer
graphics. How Lucasfilm happened. Star Trek. Star Wars. Ravi
Shankar. Steven Spielberg. Sylvester Stallone. Special effects.
Do you remember III, DP, Abel, Omnibus, Digital Effects,
MAGI? What Pixar means. How it feels to spin off. Luxo Lamps
and Academy Awards. How is JCGL related to CGL? The Japanese
and Europeans. How the Texas Panhandle contributed to graphics.
A glimpse at the future. And lots, lots more.
