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. +-- In the Real World ----------+--- Elsewhere ---------+ |Dr. John P.

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. ------------------------------ End of INFO-GRAPHICS ********************
